1. Type A only, and Type A means something specific. Type A is a treatment classification, not a quality grade: natural jadeite, cut and polished, never acid-bleached, never polymer or resin impregnated, never dyed. Type B, Type C and B+C are all still technically "real jadeite" — which is exactly how they are sold elsewhere — and worth a fraction of natural stone. We do not stock them at any price.
2. We buy our own rough at Hpakant. Gem-quality jadeite forms only where tectonic plates subduct at particular pressures, and the overwhelming majority of jewellery-grade material comes from a single district in northern Myanmar. Hong travels there several times a year, working with licensed dealers he has known for years, and selects stones at the boulder stage for texture and water — not finished pieces from a wholesaler's tray. More about how BMjade started.
3. We grade on water before colour. Jadeite is priced on three axes and carat weight is not one of them. Colour matters, but translucency — what the trade calls water (种水) — multiplies it: a vivid green that is also icy sits far above the same green in opaque material. Hold a piece to the light and you can see the difference yourself.
4. Texture is the third axis, and the one that shows. The fineness of the interlocking crystal grain decides how the polish reads. Top material looks like frozen water under a loupe; coarser stone shows visible granularity. Fine texture also produces cui xing (翠性) — the tiny frost-like glints natural jadeite throws under angled light, which glass and heavily treated material cannot reproduce.
5.A certificate with every piece — and money behind it. Every piece ships with an NGTC certificate whose serial number you can check on the issuing laboratory's own website, before you order or years afterwards.
