How to Tell If Jade Earrings Are Real: The Pair Test, Post Checks and Certificates

The question we hear most about jade earrings, more often than whether the jade is Type A, is some version of "This isn't just a thin slice glued onto something, is it?" To tell if jade earrings are real, check both stones rather than one, look at the back and the post as closely as the front, and make sure the lab report covers the pair, because only a report can confirm that jadeite is Type A. The doublet worry is fair, but in our experience doublets are the second most common fake on earrings. The first is real jadeite that has been bleached, filled and dyed, which no home check can rule out, and that's why every pair of authentic jade earrings we sell comes with one report covering both.

The principles behind every check below are in our guide on how to tell if jade is real. Earrings are harder to check than a bangle or a pendant: the stones are small, a metal rim can hide their sides, glue can hide their edges, and the post and setting make the water test useless.

Are Most Jade Earrings Fake?

We can't put a number on how many jade earrings are fake, but we know which fakes turn up most: real jadeite that has been bleached, filled and dyed comes first, then doublets, then bleached and filled jadeite on its own, then glass and resin, with dyed jadeite on its own the rarest. That order comes from what we see buying and handling commercial goods, not from a survey.

At the cheapest end of the market, nearly all the fully colored studs we've examined are Type B+C: bleached with acid, impregnated with polymer and dyed. Type B on its own we see mostly in icy and qingshui styles, pale, evenly tinted, translucent jadeite, filled to hide cracks without added color. Dye on its own turns up less often in our experience, because dye doesn't fill cracks: on a small cabochon it collects in them and shows, so sellers who dye usually fill as well.

At home, treatment can only raise suspicion, because treated jadeite is still jadeite and can look right in every other way. Type A jadeite has had no bleaching, polymer or dye and carries at most a thin polishing wax; our guide to how bleached and dyed jadeite is made explains Type A, B and C. On drop and bead earrings the drill hole is one more place to look, since dye collects there, as our necklace guide on reading the drill holes on jade beads explains. The warning signs are color that looks brighter and more even than the price allows, a fine net of etched lines on the polish under a 10x loupe, and color gathered in cracks, around a drill hole or along the edge of the stone.

Could a Jade Earring Be a Doublet?

A jade earring can be a doublet, and in our experience doublets make up a bigger share of studs than of rings or pendants, because a bezel wrapped around a small cabochon hides its side completely. The usual doublet puts a wafer-thin slice of natural, fully colored jadeite on top of a base of colorless jadeite, quartzite or even glass, bonded with clear resin. From the front it looks like a thick cabochon with full, even color, and most beginners can't see the difference. Triplets, with a green glue layer between two colorless slices, are rarer in earrings; our ring guide explains how jade doublets and triplets are built.

To check, look at each stone from the side where it meets the metal. Color that stops at a flat plane, a fine line running around the edge, or a top that's greener than the base all point to an assembled stone. Online, ask for a side photo of each earring. If the bezel and a closed back hide the edge completely, a home check can't settle the question, but a lab can.

Hollowed, Foiled and Painted Backs

Hollowing the back of a cabochon, lining a closed setting with foil or green paint, and closing the back completely are all common in jade earrings, far more so than in rings or pendants, because a small, thin stone can look dull or pale. Each works differently. Hollowing thins the stone, so light travels a shorter path through it and it looks more translucent. Foil, green paint or a bright metal back reflects light back through the stone, which makes its color look richer and more even.

In our view none of these makes a pair fake, but they aren't all the same thing. Hollowing is a cutting choice and a closed back a setting choice: a hollowed stone is still natural jadeite if it was natural to begin with. Foil, green paint or a colored lining change how the color looks face-up, so they should be disclosed, and GIA classes paint applied to the back of a gem as a treatment, called backing: the stone may still be untreated jadeite, but not all of the color you see is its own. What misleads is a thin, backed stone sold as a thick, fully colored one at a thick stone's price. Ask the seller whether the back is open or closed, whether the stone is hollowed, what sits behind it, and for a photo of the back.

Are My Jade Earrings Glass?

Glass and resin jade earrings are usually small molded donuts, called ping an kou, and Buddha studs, and they're the fakes you're most likely to catch at home. Start with the carving, though it settles less than it seems: two studs identical down to the last detail can come from a mold, but much commercial jade is machine-carved too, so identical carving is a reason to look closer rather than a verdict.

Then clean both earrings, since makeup, perfume and hairspray leave a film that makes jade look dull, and our guide to cleaning jade earrings shows how. Hold the pair side by side in a dim room and shine a small white light through both from behind:

• Round bubbles or swirl lines in the body of the stone point to glass or resin. Bubbles in a filled crack or in the glue under the stone are different: they don't make the stone glass, though a filled crack points to treatment.
• Jade usually shows grain or fibers under strong light, but fine-grained jadeite in a stone this small can look very even, so even light alone doesn't make a stone glass. A grainy look isn't proof either, since devitrified glass can show one.
• Jadeite ranges from completely opaque to semitransparent, so a stone that blocks the light isn't suspect for that reason alone. A closed back blocks it too.

Under a side light and a 10x loupe, jadeite often shows cui xing, tiny frost-like glints where light catches the flat faces of its crystal grains. They point to jadeite rather than glass, but treated jadeite keeps its grains, so they say nothing about treatment. A jade hoop carved from one piece gets the same checks, and under a side light it's also worth following the whole curve: a crack across a hoop weakens it far more than a fine stone line running along it.

Is It Mo Cui, Black Glass or Obsidian?

Mo cui is a black jadeite, often rich in omphacite: it looks evenly black in reflected light, but a strong flashlight pressed against a thin part of the stone usually shows green through it. Black glass and obsidian are common substitutes in cheap earrings. In our experience black glass lets through a bluish gray-green light or stays dead black, and obsidian lets through almost no light, at most a faint yellowish brown. A thick stone or a closed back can block the light even on real mo cui, so a missing glow doesn't rule it out and a green glow doesn't confirm it; the lab report names the material.

Should Both Jade Earrings Look Exactly the Same?

Two real jade earrings should look close but not identical: under a 10x loupe their grain, flecks and cottony white patches usually differ a little, more like sisters than twins. Fine, clean material can look almost identical, though, so a close match on its own isn't a warning sign; how closely a pair matches mostly reflects how carefully it was matched.

We match pairs at two levels. We cut high-end and collector pairs from the same piece of rough, so that translucency, base color and depth of color agree. Ordinary pairs are chosen from cabochons of the same batch and grade, picking the two that look closest. The standard we work to is no visible color difference face-up, length and width within 0.2 mm of each other, and thickness within 0.3 mm. How well a pair is matched is a question of quality more than authenticity, and our buying guide covers choosing a well-matched pair.

To compare a pair, photograph both stones side by side with a light behind them, so differences in glow and texture show in one frame. If one stone shows signs of treatment, test both: a pair can be made up of two different stones, and only a report covering both earrings tells you about each.

Five Quick Questions About Jade Earring Authenticity

Can you weigh jade earrings in water?

Weighing jade earrings in water doesn't give a useful answer. The post, the setting and any glue add weight that isn't jade, and even a bare stud is too light for a home jewelry scale to read precisely. The water test works on a bangle or a solid ring; on earrings, rely on the flashlight, the back and the report.

Are lavender jade earrings dyed?

Lavender jade earrings can be natural or dyed, and purple is one of the colors dye imitates best. When the Gem and Jewelry Institute of Thailand examined 15 purple jade beads from one dealer in Mandalay's jade market, all 15 were jadeite and 12 had been dyed. Natural lavender jadeite is usually a light purple or grayish violet, so a strong, saturated purple pair deserves a report that names the stones 翡翠, jadeite, with no treatment noted.

Why don't my nephrite earrings look glassy?

Nephrite earrings usually look oily or satiny rather than glassy, and that's normal. Nephrite, including Hetian jade, is a mass of microscopic fibers, so it doesn't show jadeite's frost-like glints under a side light. It still gets the same checks for glass, resin and dye, and a Chinese report names it 和田玉, Hetian jade.

Why does one of my jade earrings look darker than the other?

One jade earring can look darker than the other for ordinary reasons: the light falls on them differently, one stone is slightly thicker, one carries more makeup or skin oil, or the two natural stones differ a little. Clean both and compare them side by side under the same light. If one is still clearly darker or less translucent, ask the seller about it, and if you suspect one stone was swapped, compare the pair with the photo on its report.

My jade earring chipped. Does that mean it's fake?

A chip doesn't mean a jade earring is fake: natural jade chips under a knock, and the edge of a cabochon, especially where it sits in a glued cup, is the most exposed part. A chip does affect value, which depends first on what the stones are and then on their color, translucency, texture and match. Our guides cover repairing a chipped jade earring and what jade earrings are worth.

What Do the Back and Post of a Jade Earring Tell You?

The back and post of a jade earring tell you how the stone is held, whether glue is covering a flaw, and what the metal is. They deserve as much attention as the stone: in our workshop, the metal parts of earrings fail far more often than the jade.

Glued or Set: How Is the Stone Held?

Jade studs are either glued onto a post or cup, or held by a bezel, a metal rim around the stone, or by prongs. Glue does more than hold the stone. In cheap goods it's routinely used to cover small chips and fine cracks along the edge of a cabochon, and once the glue is in, the flaw is hard to see. The three checks we run on every pair's settings before listing work at home too:

1. Run a fingernail around the rim of the setting. A rough edge or a ridge of excess glue is worth a closer look.
2. Shine a light from the side into the gap between the stone and the metal, looking for a chip or a fine crack at the stone's edge that the setting or glue is covering.
3. Shake the earring gently. The stone shouldn't move or rattle.

Check the post as well: it should be straight, with a smooth joint that doesn't catch hair, and it should slide in and out of its back without forcing. On drop and threader earrings, look at every join where jade meets metal, because a cap or wire can cover a chip in the same way glue can.

What Does an S925 or 14K Stamp Prove?

An S925 or 14K stamp on jade earrings describes the post and setting, not the jade: a genuine silver or gold setting can still hold glass, a doublet or treated jadeite. 925 means sterling silver, 92.5 percent silver; 14K, also stamped 585, and 18K, stamped 750, mean 14-karat and 18-karat gold. Under US law, a company that stamps a gold or silver quality mark must also stamp its trademark or name beside it, so a quality mark standing alone is worth a question. "Hypoallergenic" and "nickel-free" describe the metal too and say nothing about the stone, and a gold-plated post isn't solid gold even when the two look the same. When the setting is precious metal, an NGTC report can include the lab's own test of it, whatever the stamp says. Our earrings are S925 sterling silver, some of it gold-plated.

How to Tell If Vintage Jade Earrings Are Real

Vintage jade earrings get the same checks as new ones, and their age proves nothing about the jade: old earrings can hold dyed jadeite, glass or a doublet as easily as new ones. Antique and old jade earrings are often clip-on or screw-back, and some are set in gold, so read the stamps on the clip, screw or post (14K, 18K, 585 or 750 for gold; 925 or STERLING for silver) and remember that a stamp describes the metal.

A standard identification report doesn't date a stone either. It says what the jade is and whether it has been treated, not when it was cut. Our guide to how jade is tested and appraised explains what each document tells you. For earrings that may be valuable, or that you want to insure, the lab report comes first and the appraisal second, because the appraiser needs to know what the stones are before putting a figure on them.

What Should a Jade Earring Certificate Cover?

A jade earring certificate should cover both earrings, either as one report for the pair or as one report for each, because a report for one loose stone, or for one earring, says nothing about the other. Read it for four things:

• The item: the pair, or the earring that report covers, with a photo that matches yours in shape, color and setting. On earrings with several jade parts, check which parts the report covers.
• The material and its treatment. On an NGTC report, jadeite is named 翡翠, and our reports for Type A stones also carry 翡翠（A货）, Type A jadeite, in the remarks; treated jadeite is named 翡翠（处理）, and nephrite is named 和田玉.
• The metal, when the setting is gold or silver and the lab has tested it.
• The report number and security code. Type the lab's address into your browser yourself rather than scanning a QR code, and enter both; our walkthrough on reading an NGTC report line by line shows each field.

Our NGTC reports are issued for each finished pair, with both earrings in the photo, and before your order ships you can ask us for a photo of both earrings together under the same light. Every pair carries our Lifetime Authenticity Guarantee, which has no time limit: if NGTC, GIA or another qualified, independent gemological lab reports in writing that a pair isn't the jade material stated on its product page, or that its Type A jadeite has been bleached, impregnated, dyed or otherwise treated, we refund the full price paid and reimburse a reasonable, documented testing fee and the reasonable cost of an approved tracked return. A lab note of surface wax alone doesn't qualify, since a thin polishing wax is a standard finish on jade. Separately, our 30-day returns policy lets you try a pair on before you decide.

If a report number checks out on the lab's site but the photo shows a different pair, the report isn't for your earrings. A matching photo makes it likely, not certain, that it is; if anything doesn't fit, have the lab examine the earrings themselves.

I'm Hong, founder of BMjade. We match every pair of our earrings by hand and check its posts, backs and settings before it's listed. If you're weighing up a pair from another seller, send photos of the front, side and back through our contact page and I'll tell you what I can see, free of charge. Our About us page explains how we source and certify each piece.
