What Is Type A Jade?

The Untreated Jade Guide Every Buyer Needs

If you've spent any time researching jade jewelry, you've likely encountered the terms Type A, Type B, and Type C. These classifications are the jade industry's shorthand for a critical distinction: whether a stone has been chemically treated, and if so, how. Understanding them is not optional for any serious buyer — it is the foundation of making an informed purchase.

At JADEscape, every piece in our collection is Type A. Here's exactly what that means, and why it matters.

The Three Types of Jade Treatment

Type Treatment What It Means
Type A None Natural jade, untreated except for surface waxing. Color and structure are entirely natural.
Type B Bleached + polymer-impregnated Acid-bleached to remove impurities, then filled with resin or polymer to restore structural integrity. Color may be natural but structure is compromised.
Type C Dyed Artificially colored, often combined with Type B treatment. Color is not natural to the stone.
Type B+C Both Bleached, polymer-filled, and dyed. The most heavily treated category.
"Type A jade is the only category in which the stone's color, translucency, and internal structure are entirely as nature created them."

Why Treatment Matters Beyond Ethics

The issue with treated jade is not only one of disclosure — it is one of durability and longevity. Type B jade, impregnated with polymer resin, will degrade over time. The resin yellows, cracks, and loses its bond with the stone. A piece that looks beautiful in the shop may look very different in five years.

Type A jade, by contrast, is stable. It does not degrade. A well-cared-for piece of Type A jadeite will look the same in fifty years as it does today — which is why antique jade pieces retain and often appreciate in value, while treated jade does not.

This is also why Type A jade commands a significant price premium. You are paying for permanence.

How to Identify Type A Jade

Without laboratory testing, definitive identification of jade treatment is difficult. However, there are indicators that experienced buyers use:

  • Surface texture: Type A jade has a smooth, slightly waxy surface. Type B jade may feel slightly sticky or have an uneven surface texture where resin has pooled.
  • UV fluorescence: Under long-wave UV light, polymer-impregnated jade often fluoresces blue-white. Natural Type A jade typically shows little to no fluorescence.
  • Price: Vivid, translucent jadeite at very low prices is almost certainly treated. Fine Type A jadeite is expensive because it is rare.
  • Seller transparency: A reputable seller will state the treatment status of their jade clearly and be able to provide documentation or laboratory certificates for significant pieces.
"The best authentication tool is a seller who welcomes your questions — and can answer them."

Type A Jade at JADEscape

Every piece in the JADEscape collection is Type A — natural, untreated jadeite or nephrite, sourced from documented origins. We carry Guatemalan jadeite from the Motagua Valley, Canadian nephrite from British Columbia, and Kazakh jadeite from the Itmurundy deposit. None of our jade is bleached, polymer-impregnated, or artificially colored.

We believe you deserve to know exactly what you're wearing. That commitment to transparency is not a marketing position — it is the foundation of everything we do.
