Jade

A general term for jade materials that can cover Fei Cui (Jadeite Jade), Nephrite and others; when used, it must be pinned down to the specific material and treatment status. This page compares how the major standards and institutions name it, what must be disclosed when selling it, whether it can be worn every day, how it is treated and identified, and which source each conclusion comes from.

Price, rarity and origin are outside the scope of this wiki.

FAQ

Questions people ask about Jade

Every sentence below is followed by the registered fact it rests on; answers add no new facts and promise no outcome.

Q1How can you tell real jade from a look-alike?

Not by name or looks: jade is an umbrella word spanning several distinct materials, and the name or appearance alone cannot determine mineral identity, naturalness, treatment or origin.GIA Jade DescriptionThe word jade has at times been wrongly applied to various gems and ornamental materials that resemble it.GIA Jade DescriptionBecause jade is a mixed aggregate, laboratories combine appearance, standard gemmological tests, chemistry and spectroscopy rather than relying on one method.LMHC Information Sheet #11Whether one particular bead is natural, treated or synthetic — only a laboratory report can settle that.What this page can answer

Q2What counts as jade: jadeite, nephrite or something else?

Gemmologists have long treated jadeite and nephrite as the materials properly called jade, and a few green omphacites have been added more recently.GIA Jade DescriptionOn laboratory reports, jade is a trade name covering aggregates of jadeite, omphacite, kosmochlor or nephrite, further specified by the mineral present.LMHC Information Sheet #11All are metamorphic rocks built from tiny interlocking mineral crystals, and this structure is what makes them exceptionally tough.GIA Jade DescriptionMuseum records also use jade as an umbrella term, so each object's specific material, nephrite or jadeite, has to be resolved.Cleveland Museum of Art 1953.628 · The Met 1989.314.1 +3

Q3Is jade often treated or dyed?

Yes: dyed, bleached-and-impregnated, coated or heated jade is common.GIA Gem Encyclopedia (care guide)For selectively dyed nephrite carvings, AGTA advises keeping them from chemicals, ultrasonic cleaners and strong light.AGTA Gemstone Information Manual, 17th ed.Whether one particular bead is natural, treated or synthetic — only a laboratory report can settle that.What this page can answer

Q4Is jade tough enough for a bangle worn every day?

Jadeite and nephrite are both exceptionally tough and rarely break or chip, yet they can still be scratched.GIA Gem Encyclopedia (care guide)Jadeite is 6.5–7 and nephrite 6–6.5 on the Mohs scale, so some care is needed to avoid scratches.GIA Gem Encyclopedia (care guide)A jeweller's torch flame is hot enough to damage jade.GIA Gem Encyclopedia (care guide)

Q5How should you clean jade, and can it get wet?

Warm water with mild soap is always safe; ultrasonic and steam cleaning are considered safe only for untreated jade, and because jade may have been treated, the soapy water method is the safe choice.GIA Gem Encyclopedia (care guide)Keep jade away from warm acids, which can affect it.GIA Gem Encyclopedia (care guide)

Q6How do jadeite and nephrite form?

Jadeite-type jade, or fei cui, forms in subduction zones, where oceanic crust is carried deep into the earth, creating a high-pressure, relatively low-temperature setting that favours jadeite crystallization.G&G Summer 2023Its bodies form veins or pods within serpentinized peridotite.G&G Summer 2023Nephrite forms by hydrothermal metamorphism, either when silica-rich fluids infiltrate dolomite-rich rocks or when calcium-rich fluids react with serpentinites.G&G Summer 2023The sources give no absolute age or growth duration for jade, only its formation settings.G&G Summer 2023

Q7Can jade change colour in the sun?

Light does not alter jade.GIA Gem Encyclopedia (care guide)Selectively dyed nephrite carvings are an exception, and AGTA advises keeping them from strong light.AGTA Gemstone Information Manual, 17th ed.

Q8What makes good-quality jade?

For jadeite jade, GIA ranks the three most important qualities, in order, as colour, transparency and texture.GIA Jade Quality FactorsThe best jadeite is semitransparent, so that text read through it appears only slightly blurred.GIA Jade Quality FactorsFor nephrite, CIBJO's reference guide for retailers says collectors value strong natural colours, pieces carved into symbols and sophisticated carvings.CIBJO Retailers' Reference Guide (2021)The pure white nephrite known in the trade as 'mutton fat jade' is highly appreciated.CIBJO Retailers' Reference Guide (2021)

Q9What does jade symbolize, and does it have healing powers?

There is no scientific evidence that jade has healing powers: the UK advertising regulators ASA and CAP state that they have not seen evidence that crystal therapy can treat medical conditions.ASA/CAP guidance (UK)Its recorded cultural role in birthstone lists is as an alternative for March on the chart of the U.K. National Association of Jewellers.Cultural recordsMuseum objects catalogued as jade come from China, Mesoamerica and Costa Rica, such as a Shang–Zhou piece of about 1200–900 BCE and a Maya piece of 400–900 CE, showing several jade materials used independently in different regions.Cleveland Museum of Art 1953.628 · The Met 1989.314.1 +3

Material research: formation, causes and history

What authoritative sources say about how this material forms, what causes its colour and optical effects, where its name comes from and how people have used it. Each statement carries an evidence grade and its sources; it describes the material in general, not any specific piece.

How it forms

'Jade' is an umbrella term, not a single species, covering jadeite (fei cui) and nephrite and, in qualified usage, some omphacite-bearing material; these are metamorphic rocks of tiny interlocking crystals and are exceptionally tough. Fei cui (jadeite-type) forms in subduction zones where convergent margins subduct oceanic crust deep, creating a high-pressure, relatively low-temperature environment favouring jadeite crystallization, with bodies as veins/pods in serpentinized peridotites. Nephrite forms by hydrothermal metamorphism (metasomatism): either silica-rich fluids infiltrate dolomite-rich rocks, or calcium-rich fluids interact with serpentinites. The word 'jade' has sometimes been erroneously applied to many similar-looking materials.

Scope: Covers an overview of the formation of the umbrella term "jade"; since it covers several different materials, formation content follows the sources for jadeite (fei cui) and nephrite respectively, without conflating the two.

Sources GIA Jade Description · G&G Summer 2023

Where it forms

Jadeite-type jade: subduction zones, high-pressure relatively low-temperature; as veins/pods in serpentinized peridotites.

Sources G&G Summer 2023

Nephrite: hydrothermal metamorphism (metasomatism), in which silica-rich fluids act on rocks rich in dolomite, or fluids rich in calcium act on serpentinites.

Sources G&G Summer 2023

How it forms, step by step

  1. (Jadeite-type) oceanic crust subducts deep along a convergent margin, creating a high-pressure, low-temperature setting.

    Sources G&G Summer 2023
  2. (Jadeite-type) jadeite crystallizes as veins/pods in serpentinized peridotites, later exhumed/exposed.

Supporting findings

Fei cui jade (dominantly jadeite) is produced in subduction-zone settings where convergent margins subduct oceanic crust deep within the earth, creating a high-pressure, relatively low-temperature environment favourable for jadeite crystallization.

Evidence grade A

Scope: Applies to jadeite-type jade (fei cui); not nephrite.

Sources G&G Summer 2023

Nephrite jade arises through hydrothermal metamorphism, i.e. metasomatism, along two possible routes: silica-rich fluids may infiltrate rocks rich in dolomite, or fluids rich in calcium may react with serpentinites.

Evidence grade A

Scope: Applies to nephrite; two parallel mechanisms given as 'either…or…'.

These are localities recorded by authoritative sources, not an origin finding for any individual piece. The CIBJO Gemstone Book (2022, §4.2.3) says a place of origin names where a gem was mined or harvested, is a matter of opinion, does not imply a level of quality, and that cutting, processing or exporting centres must not be used to imply origin. See the origin determination guide and the overview of recorded localities.

Human use and museum objects

In museum records "Jade" is an umbrella term covering nephrite (tremolite) and jadeite; e.g. Cleveland 1953.628 (c. 4700–2920 BCE, nephrite) and The Met 1993.114 (1st–5th century, Costa Rica, Jadeite) and 1989.314.1 (10th–4th century BCE, Olmec, Jade) fall under different materials within that umbrella, so each object's specific material must be resolved rather than replaced by the umbrella term.

Evidence grade A

Scope: Catalogue objects attest only to the existence and dating of those individual pieces; they are not evidence that the material was in common use in antiquity, nor do they attest to the origin, naturalness or treatment of any modern sample. Cultural attributions follow the museum's records and are not extended.

Other research findings

Gemologists have long treated jadeite and nephrite as the substances properly called jade; a few green omphacites have been added to that definition more recently. All are metamorphic rocks built from tiny, interlocking mineral crystals, and this structure is what makes them exceptionally tough.

Evidence grade B

Scope: Defines 'jade' as an umbrella term (jadeite, nephrite, and qualified omphacite); does not claim it is a single species.

Sources GIA Jade Description

Jadeite-type jade is dominated by the pyroxene jadeite (NaAlSi2O6) and may also contain related minerals such as omphacite; its bodies form veins or pods within serpentinized peridotite.

Evidence grade A

Scope: Describes jadeite-type composition and habit; not nephrite.

Sources G&G Summer 2023

The word 'jade' has at times been wrongly applied to various gems and ornamental materials that resemble jade; when the term is used, it must be resolved to one specific material.

Evidence grade B

Scope: Defines the misapplication risk of the umbrella term; does not claim any named material is jade.

Sources GIA Jade Description

For jadeite jade, the three most important qualities, in order, are colour, transparency and texture; the best jadeite is semitransparent, so that text read through it appears only slightly blurred.

Evidence grade B

Scope: Covers jadeite jade only, as described by one educational source; not a grading standard and not a statement about the value of any piece. Nephrite is covered separately.

Sources GIA Jade Quality Factors

For nephrite, collectors value strong natural colours, pieces carved into symbols and sophisticated carvings; the pure white variety known in the trade as 'mutton fat jade' is highly appreciated.

Evidence grade B

Scope: Covers nephrite only, as described in a trade association's reference guide for collectors; not a grading standard and not a statement about the value of any piece.

Names

For Jade, "Jade" must not be used as a name (GB/T 16552—2017 §5.1.1 d); GB/T 16552—2017 §5.1.1 c); 16 CFR Part 23 §23.25(a)).

Chinese standard nameThe name Jade (as a collective term) is not listed in the standard, and GB/T 16552—2017 requires the basic name to be established by testing. Trade and mineralogical namesThe trade name or synonym is Jade, an English market name that must not be used as a product name; the related high-risk name for jade does not denote a single mineral species, so products must state the specific material. Recommended listing nameThe suggested listing name is the specific material: jadeite Fei Cui, nephrite, or Fei Cui as confirmed by a certificate. Names in four languagesNames are registered in four languages: Simplified Chinese and Traditional Chinese (both as a collective term), English (Jade, a collective term that must state the specific material) and Japanese (with the material to be specified); the wording used by the GSJ (Japan) for the Japanese name is not yet verified by this site. Institution usageOn authority wording, the wording of GIA and CIBJO is recorded; the FTC text on file has no wording for this name (checked), and Gem-A is unchecked. The qualifier “collective term; must state the specific material” shown for FTC and Gem-A comes from the entry's own English name for Jade and does not represent the position of the FTC or Gem-A. Trade and mineralogical namesThe mineralogical name is a general gem-material term that can cover jadeite Fei Cui, nephrite and, with restricted usage, omphacite-bearing material.

What it is and how it's identified

Jade (the collective term), as a trade name in certificate contexts, covers aggregates formed of jadeite, omphacite, kosmochlor and nephrite, further subdivided by constituent mineral; the LMHC information sheet defines Jade as a trade name covering aggregates of fibrous or granular crystals. The LMHC information sheet notes that jade is an aggregate of several minerals and recommends that identification combine appearance, standard gemmological tests, chemical analysis and spectroscopy rather than relying on a single method. The CIBJO laboratory protocol places Jade (the collective term) under jadeite jade; for identification see identification on the Jadeite Jade entry, and the list of required methods is on the laboratory testing page.

Care

Jade — care (cleaning): Ultrasonic cleaning is considered safe only when the jade is untreated; dyed, bleached-and-impregnated, coated or heated jade is common; steam cleaning is likewise safe only for jade that has not been treated; because jade may have been treated, warm water with mild soap is the method that is always safe.
