If you've seen a smooth circle of jade with a hole in the middle, hanging from a red cord or a fine chain, chances are you've seen a Ping An Kou (平安扣), the jade peace buckle. It carries no animal, no deity and nothing that has to face a particular way. Its meaning is in its name and its shape.
If you're choosing one, we offer two Ping An Kou necklaces, each with an NGTC certificate you can verify. Our green nephrite jade peace buckle necklace is a 24.0 mm buckle, 5.3 mm thick, in soft, even yellow-green Hetian nephrite from Xinjiang, hung from a gold-plated S925 sterling silver bail with an openwork scroll design on a 45 cm (17.7 in) gold-plated silver chain. Our blue-green jadeite Ping An Kou necklace is a Type A jadeite buckle of about 20 mm with 18K gold metalwork, on a 45 cm chain. For the wrist, there's a linked Ping An Kou jadeite bracelet, a blue-green jadeite Ping An Kou bracelet and a green nephrite Ping An Kou bead bracelet.
This guide covers what the Ping An Kou means, what it's called in English, how it relates to the ancient bi disc, the sizes and colors to choose from, the mother-and-child buckle, and how to wear and buy one. For other traditional carvings, see our jade pendant meanings guide.
Quick Answer: What Does a Ping An Kou Jade Pendant Mean?
A Ping An Kou jade pendant means peace and safety. The name says so directly: 平安 (ping an) means safe and well, and 扣 (kou) means a button, clasp or buckle, so the pendant reads as a jade "peace buckle" that holds a wish for safe, smooth days. Its round shape adds wholeness, and its open center is commonly read as smooth passage.
If you're wondering what a jade circle pendant means, this is usually the answer: a plain ring of jade with a center hole, worn as a pendant, is most often a Ping An Kou. Because it has no figure, it suits any age, gender or belief, and it's a classic gift for travelers, students, elders and couples.
What Is a Ping An Kou Called in English?
A Ping An Kou is most often called a peace buckle in English, and shoppers also describe it by its shape: jade circle pendant, jade donut or jade ring pendant. Some of those names are exact; others cover more than one kind of pendant.
| Name | What it usually means | How to tell |
|---|---|---|
| Ping An Kou (平安扣), also written Ping'an Kou or Pingan Kou | The Chinese name for this pendant, and the one that carries the meaning | A smooth, round ring of jade with a center hole |
| Peace buckle | The standard English translation of 平安扣 | The same object; "buckle" translates 扣, which covers buttons and clasps, not just belts |
| Safety buckle | A looser translation used in some listings | The same object |
| Jade donut (or doughnut) | A shape description used in Western listings | Usually a Ping An Kou, though the term describes only the shape |
| Jade circle pendant, jade ring pendant | A plain description of the shape | Often a Ping An Kou, but the words can also mean a carved ring or another round design |
| Jade disc pendant | A flat disc with a hole | May be a Ping An Kou or a design modeled on the ancient bi disc |
A name says nothing about the stone. Whatever a seller calls the pendant, check what the material is and how it was treated.
Ping An Kou and the Ancient Jade Bi Disc
The Ping An Kou shares its form with the ancient jade bi disc, a flat ring of jade with a central hole known from Neolithic China, but the two are not the same object, and the link deserves care.
The Smithsonian's National Museum of Asian Art notes that thousands of jade bi discs have been recovered from elite Liangzhu burial sites, but that their exact meaning and purpose remain unknown. Smarthistory likewise explains that Neolithic bi and cong clearly held great significance while their precise meaning remains a mystery. Later, the meaning is clearer: describing an Eastern Han bi disc from about 100 to 150 CE, the same museum writes that "according to early Chinese texts, they are symbols of heaven."
Meanings changed over those thousands of years, and no source traces a single meaning from the Neolithic disc to today's pendant. The accurate claim is a modest one: the Ping An Kou continues the long tradition of round jade with a central opening, and its peace-and-safety meaning is the one its name gives it. When that meaning first attached to the form isn't documented.

What the Ping An Kou Shape Means
The Ping An Kou's meaning comes from its name and its shape, which is why it needs no carved figure.
The outer circle stands for wholeness. A circle has no corners and no beginning or end, and in Chinese tradition roundness (圆满) means completeness; it's the same reason an unbroken jade bangle is passed down as an heirloom.
The center hole is commonly read today as smooth passage, a path left open. Together with the ring, the pendant says whole, and moving freely.
The smooth surface keeps the wish gentle. There's no expression, posture or direction, so the Ping An Kou offers symbolic protection without the guardian imagery of a Pixiu or a dragon, and it suits any wearer equally.

Who Wears a Ping An Kou, and Who to Give One To
A Ping An Kou suits almost anyone, because it carries no gender, age or religious association, and it's a common jade gift in Chinese families. What changes from one recipient to the next is the wish it carries.
| Recipient | What it says | What to choose |
|---|---|---|
| A traveler | A safe journey | A low-profile size on a secure chain |
| A student leaving home | A safe transition and a smooth path | An everyday size on a durable cord or chain |
| A couple | Wholeness and harmony, for a wedding or anniversary | A matched pair, or a mother-and-child buckle split between two |
| An elder | Peace and family care | Any size; larger reads more formal |
| A newborn or young child | A wish for peaceful growth | A keepsake the parents hold until the child is older |
| Someone going through a hard time | Safe passage through it | Keep the gift note symbolic, never a promise of recovery |
| Someone whose beliefs you don't know | A simple wish with no figure to explain | An everyday size in green or white |
For a more understated look, dark green, black or icy stone on a cord or heavier chain works well; for a lighter look, white, pale green or lavender on a fine chain. Neither is tied to gender.
For babies and young children, treat a Ping An Kou as a keepsake rather than something to wear. The American Academy of Pediatrics does not recommend that infants wear any jewelry, because necklaces carry strangulation and choking risks. A newborn's Ping An Kou can be kept by the parents until the child is older; an older child should wear one only with an adult watching, on a short, secure cord, and never to sleep.
A gift note that works:
This Ping An Kou is a wish for peace, safety, and smooth days ahead.
Ping An Kou Styles: Plain, Set, Carved and Mother-and-Child
A Ping An Kou comes in a few distinct styles, and the plain buckle is the classic.
Plain Ping An Kou (素面)
A plain Ping An Kou is nothing but form, polish and the stone itself. With no carving, the material has nowhere to hide, which makes a plain buckle the clearest test of both the jade and the finishing.
Metal-Set Ping An Kou
A metal-set Ping An Kou has a gold or silver bezel around the rim, sometimes with a decorative bail. The setting protects the outer edge, which is where a dropped buckle chips, and it lets a smaller stone read larger. Because the rim is covered, rely on a certificate whose photo and total mass match the piece.
Carved Ping An Kou
A carved Ping An Kou adds light relief to the surface: a dragon coiled around the rim, clouds, a 福 character or a chain motif. Each adds its own meaning, while the plain buckle remains the classic form.
Mother-and-Child Ping An Kou (子母扣)
A mother-and-child buckle (子母扣), also called a 同心扣 ("one-heart buckle"), is two Ping An Kou cut from one piece of jade: the smaller "child" buckle is carved from the core removed from the center of the larger "mother" buckle. The two are separate pieces. Fitted together, they form one complete disc; worn apart, each person carries half. Together they stand for wholeness, and apart for the bond between two people.
Because both halves come from the same stone, their color and texture match exactly, and that match is the point of the piece. It's also demanding to make: the core has to come out whole, with no chipped edge or crack in either the outer ring or the center, so a fine same-stone pair takes more material and more labor than a single buckle. Some lower-priced sets are cut from two different stones that only fit together in shape. Their color and texture differ, and the trade doesn't regard them as true mother-and-child buckles.
Traditionally, a mother-and-child buckle is given to a mother and child, or a grandparent and grandchild: the mother wears the larger buckle and the child the smaller one, as a gift for a baby's first month (满月) or first birthday, a coming of age, or an expectant mother. For a baby, the parents keep the child's half until the child is old enough to wear it. Couples split a pair as a one-heart buckle, one half each, as a quieter alternative to rings. Close friends give them as a token of friendship, and some people keep both, worn together as one disc or apart, one on a chain and the other set as a ring or strung on a bracelet.
Larger Ping An Kou for the Home or Car
A larger Ping An Kou, roughly 60 to 80 mm and up, is made to hang in a car or a home rather than be worn. The meaning is the same, and the wish is for a safe household or a safe drive.
Ping An Kou Size Guide
A Ping An Kou of about 20 mm is a common everyday size. As a general guide, size changes how the pendant reads, not what it means:
| Diameter | Reads as | Suits |
|---|---|---|
| 15 to 20 mm | Delicate | Fine chains, layering, a minimal look |
| About 20 to 30 mm | The common everyday size | Daily wear and most gifts |
| 30 to 50 mm | More present | A statement pendant on a cord or heavier chain |
| 50 mm and up | A display or hanging piece | A car or a home rather than a necklace |
Our two necklaces sit in the common everyday range: the nephrite buckle is 24.0 mm across and the jadeite buckle about 20 mm.
Thickness matters as much as diameter. A buckle cut too thin feels fragile and hangs oddly, while a well-proportioned one has visible depth at the rim; our nephrite buckle is 5.3 mm thick. Larger pendants also need a stronger bail and cord, because jade is dense: jadeite's specific gravity is about 3.33 and nephrite's about 2.95, so a large buckle is heavier than it looks. For chain length and where the pendant sits, see the jade necklace length guide.
Ping An Kou Colors
A Ping An Kou's color changes the mood of the pendant rather than its core meaning, which stays peace and safety.
| Color | What it adds | Suits |
|---|---|---|
| White or icy | Purity and clarity; the classic peace-buckle look | The most traditional choice |
| Pale green | Harmony and a gentle daily wish | Everyday wear |
| Rich green | Prosperity and vitality alongside protection | Meaningful gifts, the classic jade look |
| Blue-green | Calm and cool; quiet and modern | Everyday wear, and anyone who finds bright green too loud |
| Yellow-green | Soft, warm and understated | Everyday wear with gold-toned metal |
| Lavender | Softness and calm | Gentle gifts, personal wear |
| Yellow or honey | Warmth and optimism | Encouragement gifts |
| Dark green or black | Grounding and quiet strength | An understated look |
| Multi-color | A layered look; each piece is unrepeatable | Collectors, one-off gifts |
Our jadeite buckle is blue-green, and our nephrite buckle yellow-green on gold-plated silver. White, icy and the softer greens suit the form well, because they match the calm it expresses.
Color matters less than what the stone is. A softer natural buckle with its treatment status stated plainly is a better buy than a vivid one with vague disclosure. GIA lists jadeite's most important quality factors as color, transparency and texture, and for a buyer, treatment status comes before all three. For color meaning and value across all jade, see jade colors and their meanings.
How to Choose a Well-Made Ping An Kou
A well-made Ping An Kou is judged on three things that have nothing to do with color: a centered hole, rounded edges and even walls.
- The hole sits in the center, so the ring of jade is even all the way around. An off-center hole shows the moment the pendant hangs.
- The outer rim and the mouth of the hole are rounded and polished, so the buckle feels smooth to a fingertip everywhere. Sharp inner edges are a sign of hurried finishing, and they fray cords.
- The wall thickness is consistent all the way around. A buckle ground thin on one side to chase a flaw hangs slightly wrong.
A plain Ping An Kou has no carving to distract from the stone or the finishing, which makes it a fair test of both.

How to Wear a Ping An Kou
A Ping An Kou is easy to wear because it has almost no rules: there's no head to point up, no face to turn outward and no direction to get wrong. It sits well near the chest or collarbone, at whatever length suits its size.
Which side of a Ping An Kou faces out?
A plain Ping An Kou can be worn either way round. If one side has carving, metalwork or a more finished polish, wear that side facing out.
Should a Ping An Kou go on red cord or a chain?
A Ping An Kou is traditionally worn on either red cord or a chain. Red cord (红绳) is the classic and carries its own protective meaning, especially in your own zodiac year (本命年); our jade necklace meaning guide covers cord colors. Silver and gold chains read more modern and last longer. On a cord, check the spot where it passes through the hole now and then, and replace the cord when it frays, thins or the knot loosens.
Can you wear a Ping An Kou every day?
A Ping An Kou is one of the easiest jade pendants to wear every day. Take it off to shower, swim and sleep, and for heavy exercise: sleeping in a necklace pulls on the bail, tangles the chain and presses the pendant into you.
Can you wear a Ping An Kou with a Pixiu or a Buddha?
A Ping An Kou can be worn with a Pixiu or a Buddha, since their meanings cover different ground: peace for the Ping An Kou, wealth for the Pixiu, contentment for the Buddha. Two separate chains at different lengths read better than two pendants on one cord.
On a bracelet, a Ping An Kou is strung as a charm or linked into the band, and it carries the same meaning. Folk custom often puts jade on the left wrist, following "left in, right out" (左进右出), but a Ping An Kou itself has no direction rule; the custom is explained in our bracelet meaning guide.
Ping An Kou vs Other Jade Pendants
A Ping An Kou is the simplest of the traditional jade pendants, and the best choice when you're buying for someone whose beliefs you don't know.
| Pendant | Main meaning | A good fit for |
|---|---|---|
| Ping An Kou | Peace, safety, wholeness, smooth passage | Daily wear, and gifts when you don't know the recipient's beliefs |
| Pixiu | Wealth and protection | New ventures and business |
| Buddha | Joy, contentment, lightness of spirit | Someone carrying too much worry |
| Guanyin | Compassion, mercy, protection | Someone leaving home, or anyone a giver wants watched over |
| Dragon | Power, authority, ambition | Leadership and big goals |
| Lotus | Purity and renewal | A fresh start |
The folk saying 男戴观音,女戴佛 ("men wear Guanyin, women wear Buddha") pairs those two figures by gender, but it's a saying, not a rule, and the Ping An Kou sits outside it entirely. The full comparison is in the 12 jade pendant meanings guide.
Buying an Authentic Ping An Kou: Jadeite or Nephrite
An authentic Ping An Kou is named as jadeite or nephrite, with its treatment status in writing and a certificate that matches the piece. Eight checks, in order:
- Is the material named: jadeite or nephrite?
- For jadeite, is it stated as Type A? For nephrite, is it stated as natural, not dyed?
- Is there a certificate, and do its photo and total mass match the pendant?
- Is the surface evenly polished, with no dull patches?
- Is the hole centered and its mouth rounded?
- Is the wall thickness even all the way around?
- Is the bail or cord secure for the weight?
- Is the price plausible for the claimed quality?
Type A means natural jadeite with no bleaching, polymer or dye; a thin polishing wax is normal finishing. It's a treatment status, not a quality grade.
Shape proves nothing about the stone, and neither does bright green on its own: vivid color is one of the things most often faked in jade. Be wary of listings that offer only phrases like natural green stone, jade color pendant, peace buckle style, lucky jade necklace or grade A look, none of which names a mineral. Our guide to how to tell if a jade necklace is real has the at-home screening method.
Caring for a Ping An Kou
A Ping An Kou is the easiest jade pendant to care for, because its smooth surface has no carving to trap grime. Wash it in lukewarm water with a drop of mild soap, wipe it with a soft cloth and dry it completely. Never use an ultrasonic cleaner.
The one spot to check regularly is where the cord or bail passes through the hole, since that's the wear point on this design. The full routine for pendant, chain and cord is in the jade necklace cleaning guide.
Ping An Kou FAQ
What does a Ping An Kou jade pendant mean?
A Ping An Kou jade pendant means peace and safety, with wholeness and smooth passage added by its round shape and open center. 平安 means safe and well, and 扣 means a buckle or clasp, so the pendant holds a wish for safe, smooth days.
What does a jade circle pendant mean?
A jade circle pendant, a plain ring of jade with a center hole, is most often a Ping An Kou, and it means peace and safety. Not every round jade pendant is one; a carved ring or a bi-style disc can look similar, so the name a seller uses is worth checking.
What is Ping An Kou called in English?
Ping An Kou is most often called a peace buckle in English. You'll also see safety buckle, jade donut, jade circle pendant and jade ring pendant; the last three describe the shape and can sometimes mean other round pendants.
Is a jade donut the same as a Ping An Kou?
A jade donut is usually a Ping An Kou: "donut" describes the shape in Western listings, while "Ping An Kou" is the name that carries the meaning. Neither name says anything about the quality of the stone.
Is Ping An Kou the same as an ancient bi disc?
A Ping An Kou shares its form with the ancient bi disc but isn't the same object. The meaning of Neolithic bi discs is unknown, early Chinese texts later describe bi as symbols of heaven, and the Ping An Kou's peace-and-safety meaning comes from its own name.
Is Ping An Kou good luck?
A Ping An Kou is widely seen as a symbol of protection and good fortune. Treat that as cultural meaning, a wish you carry, rather than a guaranteed result.
Which side of a Ping An Kou faces out?
A plain Ping An Kou can face either way, and it has no direction rule. If one side is carved, set or more finished, wear that side facing out.
Can men wear a Ping An Kou?
Men can wear a Ping An Kou as easily as women, since it has no figure and no gender association. Dark green, black or icy stone on a cord or heavier chain gives the most understated look.
Can babies and children wear a Ping An Kou?
Babies shouldn't wear a Ping An Kou or any other jewelry: the American Academy of Pediatrics does not recommend jewelry for infants because of strangulation and choking risks. Keep a newborn's Ping An Kou as a keepsake, and let an older child wear one only with an adult watching, on a short, secure cord, and never to sleep.
What size Ping An Kou should I buy?
A Ping An Kou of about 20 to 30 mm is the common everyday size and suits most gifts. Pieces of 15 to 20 mm read delicate, 30 to 50 mm reads more present, and 50 mm and up is usually made to hang in a car or a home.
What is a mother-and-child buckle (子母扣)?
A mother-and-child buckle is two Ping An Kou cut from one piece of jade, the smaller carved from the core of the larger. The two are separate: fitted together they form one complete disc, and worn apart each person carries half. Sets cut from two different stones don't match in color and aren't regarded as true mother-and-child buckles.
Who do you give a mother-and-child buckle to?
A mother-and-child buckle is traditionally given to a mother and child, for a baby's first month or first birthday, a coming of age or an expectant mother, with the mother wearing the larger half. Couples also split one, close friends give them as a token of friendship, and some people keep both halves for themselves.
Should a Ping An Kou be worn on red cord or a chain?
A Ping An Kou can be worn on either. Red cord is the classic and carries its own protective meaning, especially in your own zodiac year; a chain reads more modern and lasts longer. Replace a cord when it frays, thins or the knot loosens.
Can I buy a Ping An Kou for myself?
Buying a Ping An Kou for yourself is perfectly fine. It's a popular gift, but nothing in the tradition says it has to be given by someone else.
Can I wear a Ping An Kou with a Pixiu?
A Ping An Kou can be worn with a Pixiu; the Ping An Kou carries peace and the Pixiu wealth, so the meanings don't conflict. Two separate chains at different lengths look better than two pendants on one cord.
What does a Ping An Kou bracelet mean?
A Ping An Kou bracelet carries the same meaning as the pendant: peace, safety and wholeness. The buckle is strung as a charm or linked into the band, and it has no direction rule.
How do I know a Ping An Kou is real jade?
A real jade Ping An Kou is named as jadeite or nephrite, with its treatment status in writing and a certificate whose photo and total mass match the piece. Then inspect the polish, the hole and the wall thickness, and use the checks in our jade necklace authentication guide.
What if my Ping An Kou breaks?
A broken Ping An Kou is often said, in Chinese folk belief, to have taken a blow meant for its wearer, and people say 碎碎平安, a pun meaning "peace year after year," when something breaks. Keep the pieces: our guide to what happens when jade breaks covers what can and can't be repaired.
