Jade
Two different minerals share the everyday word: nephrite, an amphibole (tremolite to actinolite), and jadeite, a pyroxene. Much that is sold as jade is neither.
Nephrite is typically opaque, from spinach green to white, brown, or black, with a slightly oily polish and a famously tough, interlocked structure. Jadeite can be translucent, including prized glowing greens and also lavender or colorless pieces, while dyed quartzite often shows color pooled in cracks and glass may show bubbles or a too-even tint. None of these looks is a laboratory identification.
What it actually is
| Name used here | Jade |
| Mineral or material | Two different minerals share the everyday word: nephrite, an amphibole (tremolite to actinolite), and jadeite, a pyroxene. Much that is sold as jade is neither. |
| Hardness | Variable. Nephrite is about Mohs 6 to 6.5 but unusually tough. Jadeite is about 6.5 to 7. Glass, serpentine, and dyed quartzite will not match those identities even if a scratch test seems close. Do not scratch a piece you care about. |
| How it forms | Nephrite forms where amphibole fibers interlock into an unusually tough metamorphic mass, while jadeite forms under high pressure, often in subduction-related rocks. They are different geological events that people happened to admire in similar ways. |
Trade names and mix-ups
Nephrite, an amphibole, and jadeite, a pyroxene, are both legitimately called jade and are not the same mineral or the same price. New jade is often serpentine, Indian jade is often green aventurine, and Malaysian jade is frequently dyed quartzite, with glass, plastic, and dyed marble filling out the costume drawer. A shop that says only jade has not finished the sentence, and pounamu, a Māori term for New Zealand nephrite and related stone, is not a synonym you may stamp on a dyed bead.
Care
Real nephrite and jadeite are durable in ordinary wear and dislike harsh chemicals, bleach, and hard knocks against tile. Do not soak dyed jade of any kind; dye lives in fractures and leaves them. Skip salt, skip ultrasonics if the piece is composite or treated, and skip the steam cleaner. Wipe with a soft damp cloth and dry. Sun will not improve color. A soapy shower is a good way to dull a polish and a bad way to learn the mineral.
Provenance
Jadeite from Myanmar, especially the bright green associated with the Hpakant region, has been tied to dangerous mining, military control, and fatal landslides; that supply chain is not a charm. Nephrite has many sources, and New Zealand pounamu is legally and culturally vested with Māori, not a tourist souvenir to pocket from a river; buy only what a seller can name as nephrite or jadeite with a lawful origin, or buy something that does not pretend.
Symbolism
- two minerals, two histories
- a soft cloth
- not every green stone
- continuity you do not counterfeit
Folklore, only where it exists
Jade is not one story. In China, nephrite has been worked since the Neolithic, including the cong and bi of Liangzhu and, much later, the jade burial suits of the Han, and the word yu names a cultural category of virtue and craft as much as a species; jadeite from Myanmar became the imperial green favored at the Qing court, a later chapter, not the beginning. In Mesoamerica, jadeite was a material of Olmec, Maya, and later Mexica prestige, green like water and maize country, worked into celts and ornaments that are archaeological records, not DIY. In Aotearoa, pounamu is a taonga with living protocols. The Wilde Altar will not collapse those histories into a luck slogan, and it will not offer you a ritual borrowed from any of them. A tumbled dyed quartzite is not a Han disc or a Maya celt. The practice here is to learn which mineral, if either, is in your hand, and to wipe it with a cloth instead of a fantasy.
Cautions
An original practice
The Two-Mineral Cloth
- The stone sold as jade
- A soft dry cloth
- A label or a strip of paper
- A pen
- 1Write the label with one of three phrases only: nephrite, jadeite, or unidentified green stone. If you do not know, you do not know. That is the correct answer.
- 2If a seller claimed a people or a dynasty, add a second line: story, not provenance, unless you have papers that actually say otherwise.
- 3Wipe the piece once with the cloth. No oil, no water bowl, no salt.
- 4Put the label in the box with the stone. If you share a home, a partner of any gender can read the label without being inducted into anything.
- 5If the label says unidentified, and the price you paid required it to be imperial, decide whether you want that money back. The cloth will not settle it; a question to the seller might.
Two minerals have carried this word, and many more have stolen it. I will not borrow a burial or a taonga. A cloth is enough care.
Store the box away from bleach and dye-transfer. Do not wear unidentified dyed green stone in the shower to test it.
A practical action. Email or ask the seller which mineral it is, and correct the label when you get an answer worth believing.
Substitutions
- A green cloth square labeled unidentified, if you would rather not own a dubious jade
- A piece of green aventurine already labeled as quartzite, so the contrast teaches the point
Beginner questions
- Are jade and jadeite the same thing? Jadeite is one of the two minerals called jade. Nephrite is the other. Both are real jade. Most souvenir jade is neither.
- Is New Zealand greenstone free to collect on a beach? No. Pounamu is legally and culturally protected. Do not pocket it, and do not treat a tourist story as consent.
- Can jade water help the kidneys because of old medical symbolism? No. Do not make elixirs. Historical medical systems are not a drink recipe, and a dyed fake is not a traditional medicine either.
