Type A, B vs. C — The Complete Guide to Jade Treatments, Certification, and What Sellers Don’t Tell You

Jade is one of the most misunderstood gemstones in the world.

Not because it’s rare—but because the same word “jade” can describe both completely natural treasures and heavily treated, chemically altered material that looks identical to the untrained eye.

If you’re investing in jade—especially jadeite—there is one concept you must understand:

Type A, Type B, and Type C jade are not quality levels. They are treatment classifications.

And they determine authenticity, value, durability, and long-term worth.

What Is Jade (玉) — And Why It’s Confusing

In Chinese, the word 玉 (yù) does not mean jade in the narrow, gemological sense most Western buyers assume. It refers more broadly to stones that are beautiful, smooth, and worthy of admiration.

That means materials like chalcedony (玉髓) or aventurine (东陵玉) can still carry the word “jade,” even though they are not jadeite at all.

Even within true jade—翡翠 (jadeite)—there exists another layer of complexity, one that has nothing to do with origin or beauty, but everything to do with what has been done to the stone after it left the earth.

Quick Guide:

• 翡翠 (Fei Cui) → Jadeite (what most high-end jade jewelry is)
• 和田玉 (Hetian Yu) → Nephrite
• 玉髓 (Yu Sui) → Chalcedony
• 东陵玉 (Dong Ling Yu) → Aventurine

This linguistic nuance is why certificates can be misleading if you don’t know what to look for.

The Three Types of Jade: A, B, C

Type A Jade (天然翡翠 / A货翡翠)

Definition:

Natural jadeite with no chemical treatment. Waxing (上蜡) is standard and acceptable.

Type A jade is, quite simply, jade in its truest form.

It has been cut, shaped, and polished—but never altered in a way that changes its internal structure or chemistry. At most, it may be gently waxed, a traditional finishing step that enhances surface luster without interfering with the stone itself.

On a certificate, it will quietly declare itself as:

• 天然翡翠 (natural jadeite)
• A货 (Type A)
• Sometimes accompanied by 未处理 (untreated)

There is a kind of honesty to Type A jade. Its colors are not always perfectly even. Its interior may hold soft clouds—what the trade calls 棉 (cotton)—or delicate structural lines that formed over millions of years.

But these are not flaws.

They are evidence that nothing has been hidden.

And over time, Type A jade does something remarkable: it doesn’t deteriorate. It endures. In some cases, it even seems to grow more luminous as it is worn.

Key characteristics:

• Natural color distribution (色根 / color roots)
• May contain inclusions (棉, 石纹, 冰渣)
• Color is stable over time

Value:

💎 Highest value and investment-grade

Type B Jade (漂白充填处理 / B货翡翠)

Definition:

Jade that has been chemically treated and filled with polymer

Type B jade begins as natural jade—but one that did not meet the aesthetic standards of the market.

Perhaps it was too cloudy. Too stained. Too uneven.

So it is “improved.”

The process is not subtle.

The stone is submerged in strong acids—酸洗 (acid bleaching 酸洗 / 漂白)—which strip away impurities, but also erode the very structure that gives jade its strength. What remains is porous, weakened.

To restore its appearance, the jade is then infused with polymer resins—注胶 / 充填 (impregnation)—filling the gaps and artificially enhancing translucency.

For a moment, the result can be striking. Clear. Smooth. Almost too perfect.

But perfection, in this case, is an illusion.

Over time, the resin may yellow. The structure may degrade. What was once sold as luminous becomes dull, even brittle.

On a certificate, this truth is never hidden—only written in terms many buyers do not recognize:

• 漂白充填处理 (bleached and polymer-filled)
• B货
• Or more generally, 处理翡翠 (treated jade)

Chinese certificate terms:

• 漂白充填处理 (Bleached & Polymer-filled)
• B货 (Type B)
• 处理翡翠 (Treated Jadeite)

Key characteristics:

• Looks very clear but structurally weakened
• Often overly “perfect” translucency
• May yellow or degrade over time

Value:

⚠️ Significantly lower than Type A

Even if it looks beautiful today, it is not stable long-term

Type C Jade — Color That Doesn’t Belong

Definition:

Jade that has been artificially dyed

If Type B jade alters structure, Type C jade alters truth itself.

Here, the goal is color.

Jade that is too pale or too dull is subjected to 染色 (dyeing)—often in shades of vivid green or lavender, imitating some of the most valuable colors in the jade world.

To the untrained eye, it can be convincing.

But the color does not behave like natural jade. It pools in fractures. It appears overly saturated, sometimes almost glowing in a way that feels artificial.

And unlike natural color, it does not last.

With time, exposure, and wear, it can fade—leaving behind something that no longer resembles what was purchased.

Certificates will state this plainly:

• 染色处理 (dyed)
• C货 (Type C)
• 处理翡翠

Key characteristics:

• Extremely vivid or unnatural colors
• Color concentrates in cracks or grain boundaries
• Color may fade over time

Value:

🚫 Lowest value — purely decorative

When Everything Is Done — Type B+C Jade

There is a category where all of these processes converge.

The jade is bleached. Filled. Dyed.

Transformed, layer by layer, into something that looks like jade—but no longer behaves like it, ages like it, or holds any of its original value.

This is often labeled:

• 漂白充填 + 染色处理

In serious collecting circles, it is not considered jade in any meaningful sense.

The Quiet Truth Hidden in Certificates

A jade certificate does not lie.

But it does not explain itself either.

Everything you need to know is usually contained in a single section—often overlooked:

备注 (Remarks)

This is where the stone quietly declares what it has been through.

Reputable labs—such as NGTC (国检), IGG, GTC, DojiLab, and VGC—will always disclose treatments using precise terminology.

The challenge is not access to the information.

It is knowing how to read it.

What to look for:

✅ GOOD (Type A):

• 天然翡翠
• 未处理
• MA logo (资质认证标志) with Chinese Labs
• QR code that scans
• Matching weight, size, photo

⚠️ WARNING:

• 处理翡翠
• 漂白充填
• 染色

What Treatment Really Means

There is a tendency, especially in modern jewelry marketing, to soften the word “treatment.”

To frame it as enhancement. Improvement. Optimization.

But in jade, treatment is not neutral.

It is transformative.

Acid washing does not simply clean the stone—it changes its structure.
Resin filling does not simply stabilize—it replaces what was lost.
Dyeing does not enhance—it conceals.

And once these processes have occurred, they cannot be undone.

Why Type A Still Matters

There is a reason untreated jade has been revered for centuries.

Not because it is flawless—but because it is real.

It carries its history within it. Its structure has not been compromised. Its color has not been fabricated. Its value does not depend on illusion.

And in a world where so much can be manufactured to look perfect, there is something quietly powerful about a stone that simply is what it is.

A Final Thought

If you remember nothing else, remember this:

Two pieces of jade can look the same today.

But only one will still be beautiful ten years from now.

And the difference—quiet, technical, almost invisible—will always be written in a few Chinese words most people never think to read.
