Jinsha Stone
Also known asGoldstone glass (conditional name)
“Jinsha stone” is a Chinese market name that may mean goldstone (aventurine glass) or some other product; the material must be confirmed by documentation or testing. 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.

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
'Jinshashi' is a Chinese market name, and the name by itself does not establish what the material is. The cited authoritative sources offer no material-level definition of 'jinshashi', so this entry does not claim it to be goldstone glass or any natural mineral: taken most conservatively, its material identity remains unestablished. What can be confirmed is that CIBJO gives precise definitions for 'glass' (a substance, natural or artificial, that is amorphous and has solidified from a molten state) and for 'artificial product/artificial stone', and that the trade uses manufactured glass as a gem simulant capable of imitating a wide range of gems. If a particular piece of 'jinshashi' is tested and proves to be an artificial glass-type material, it should be named and have its material and treatment disclosed under CIBJO's glass/artificial-product rules; until such testing, that remains an unverified inference. The actual material requires testing.
Scope: Applies to explaining the material uncertainty and naming boundary of 'Jinsha stone' as a market name; not applicable to asserting the material of any specific sample, nor as an identification conclusion.

Where it forms
No natural formation environment applies: the subject is a market name of undetermined material identity, so no formation or manufacturing environment can be assigned from the name.
Sources CIBJO Gemstone Book 2022 · GIA Introduction to Imitation Gems
If testing later confirms an artificial material (e.g. a glass type), its 'environment' would be a manufacturing/processing one; no such claim is made until then.

How it forms, step by step
Record and verify the market name's provenance and usage, rather than inferring material from the name.
Sources CIBJO Gemstone Book 2022 · GIA Introduction to Imitation Gems
Perform material testing on the actual specimen (e.g. composition, structure) to determine its true material identity.
Sources CIBJO Gemstone Book 2022 · GIA Introduction to Imitation Gems
Once the material is established, name and disclose it under the corresponding CIBJO category (e.g. glass / artificial product / imitation).
Sources CIBJO Gemstone Book 2022 · GIA Introduction to Imitation Gems
Link to appearance
Because the material is undetermined, no single appearance–origin link can be given; appearance is only information about an untested specimen and cannot be used to infer the material.

Timescale
The sources give no date or process duration associated with 'jinshashi'.

Other research findings
The cited authoritative sources do not define the material of 'jinshashi'; it must not be automatically equated with goldstone glass or any natural mineral, and the actual material requires testing.
Evidence grade CScope: This is an absence-of-definition boundary judgement; it applies to the cited sources.
Sources CIBJO Gemstone Book 2022
CIBJO gives precise definitions for 'glass' (a substance, natural or artificial, that is amorphous and has solidified from a molten state) and for 'artificial product/artificial stone'; once the material has been established these definitions allow classification, but a market name alone is not a material identification.
Evidence grade AScope: Applies to CIBJO's definitions; it does not determine the material of any specific 'jinshashi' specimen.
Sources CIBJO Gemstone Book 2022
The trade calls a material a 'simulant' when it resembles another gem yet differs greatly in chemical makeup, crystal structure, and optical and physical properties, and manufactured glass is a frequent example; so if a piece of 'jinshashi' tests as a glass type, it should be named and disclosed as an imitation/glass. This remains an inference that only testing can confirm and is not asserted here.
Evidence grade CScope: A conditional inference (if it is a glass type); it does not conclusively equate 'jinshashi' with goldstone glass.

Limits of this research
- Research status: Only partial material-specific findings found; gaps are stated as gaps
- The cited authoritative sources do not define the material of 'jinshashi'; the actual material requires testing.
- This record does not assert 'jinshashi' to be goldstone glass or any natural mineral, nor exclude that it may be other materials.
- The sources give no date, source or process parameters for 'jinshashi', so no such claim is made.

Names
Besides Jinsha Stone, the name register records "Goldstone glass", for which no restriction on use as a name is recorded.
Trade and mineralogical namesJinsha Stone is a Chinese market and trade name whose material identity is not established; it may refer to goldstone glass or to other products, and must be confirmed by material documents or testing. Standard and listing namesGB/T 16552—2017 does not list the name, and the basic name must be established by testing; the suggested listing name is Jinsha Stone (named by the actual material after testing). Trade and mineralogical namesIf it is confirmed to be man-made goldstone glass, the trade name or synonym is Goldstone glass. Institution usageOn authority wording, the FTC and CIBJO texts on file have no wording for this name (checked), and GIA and Gem-A are unchecked; bodies without a recorded wording or unchecked show the entry's own English name, qualified as a Chinese trade name with the material unverified, which does not represent their position. Japanese namesThe Japanese name is marked as a Chinese market name with the material unidentified, and the wording used by the GSJ (Japan) for this name is not yet verified. Names in four languagesNames are registered in four languages: Simplified Chinese, Traditional Chinese, English (Jinsha Stone) and Japanese.

What it is and how it's identified
Registered material facts
Each row carries its own source and check date and can be cited on its own; “—” means the cited source gives no value, not “none”.
The material behind this trade name is unconfirmed, so no single material's facts are attached. No source consulted uses the name “Jinsha stone”. What the sources say about goldstone glass or the aventurescence of aventurine quartz is about those materials, not about goods sold under this name, so it is not borrowed. The gemmological journals consulted (Journal of Gems & Gemmology, Mineralogy and Petrology, Acta Petrologica et Mineralogica) and GIA material (Gems & Gemology and Lab Notes) contain only a similar-sounding name for a quartzite jade from Cenxi, Guangxi, which is a different name and cannot stand in for this one; encyclopaedia-type pages online call it mica-bearing quartzite in some places and man-made goldstone glass in others, so they are not used.
