Synthetic Green Quartz
Synthetically made green quartz; GB/T 16552-2017 Annex A Table A.4 lists it as "synthetic green quartz". The specific colour variety still needs separate proof. 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
Synthetic green quartz is synthetic quartz — an artificially grown silicon dioxide single crystal — in its green colour form, matching natural green quartz (prasiolite-type material) instead of forming through natural ore genesis. CIBJO deems a laboratory-grown stone to match its natural counterpart in structure, physical behaviour and chemical makeup in all essentials; as a colour type of synthetic quartz, synthetic green quartz is created by artificial crystal growth and given its green tone through doping, irradiation or heat treatment. Its parent substance being artificial, the label must read 'synthetic green quartz' and never the natural variety name alone.
Scope: Applies to explaining the artificially manufactured nature of synthetic green quartz as the green variety of synthetic quartz and its naming boundaries; does not describe the ore-forming process of natural green quartz.
Sources CIBJO Gemstone Book 2022 · G&G Summer 2014
Where it forms
A controlled laboratory crystal-growth environment: synthetic green quartz is a man-made colour variety, not a natural geological setting.
Sources CIBJO Gemstone Book 2022 · G&G Summer 2014
Natural green quartz occurrence settings (iron-bearing hydrothermal veins, geodes) do not apply; synthetic green quartz has no natural formation origin.

Link to appearance
Synthetic green quartz shares the composition and structure of natural green quartz, so its appearance can be very similar; its green colour is obtained by doping and irradiation/heat treatment, though the selected sources give no variety-specific zoning data.

Timescale
The selected sources give no growth duration or market-introduction date for synthetic green quartz.

Supporting findings
As a colour variety of synthetic quartz, synthetic green quartz is manufactured by artificial crystal growth and undergoes no natural ore-forming process.
Evidence grade AScope: States its synthetic nature; not the specific growth parameters.
Sources CIBJO Gemstone Book 2022
How it is identified
The green colour of a quartz can be produced by artificial growth or treatment, so appearance does not prove origin. Distinguishing natural from synthetic quartz takes laboratory work: twinning and colour zoning under the microscope, chemical analysis such as EDXRF, infrared spectroscopy, and where needed a polariscope (conoscope) and refractometer to read how the colour boundary relates to the optic axis. Interpretation depends on a specialist's grasp of the material's optics and morphology, so the identification should be issued by a qualified gem laboratory.
Evidence grade AScope: Applies where natural and synthetic quartz must be distinguished; no self-administered criteria are given.
Sources G&G Summer 2014 · CIBJO Gemstone Book 2022
Other research findings
Synthetic green quartz is the green variety of synthetic quartz corresponding to natural green quartz; it has essentially the same composition and structure as the natural material and is an artificial product.
Evidence grade AScope: Defines its identity and technical standing; not the genesis of natural green quartz.
Sources CIBJO Gemstone Book 2022
A synthetic stone must be named/disclosed as 'synthetic' + natural counterpart name; synthetic green quartz must follow this naming rule.
Evidence grade AScope: A naming/disclosure rule; not a specific process.
Sources CIBJO Gemstone Book 2022
Synthetic quartz can be distinguished from its natural counterpart using a combination of techniques such as inspection of twinning and colour zoning, chemical analysis and infrared spectra.
Evidence grade AScope: Evidence from a synthetic ametrine identification study; the method extends to synthetic quartz colour varieties.

What it is and how it's identified
Among the registered material facts for Synthetic Green Quartz, the following are taken for synthetic quartz (the whole class): the structure is crystalline and trigonal, with hexagonal tabular-prismatic crystals whose faces commonly show a “cobblestone” texture; Mohs hardness 7, no cleavage; density 2.64–2.69 g/cm³, with a clause value of 2.66 and a tolerance of +0.03/−0.02, from which the limits are derived; the optic character is anisotropic, uniaxial positive, refractive index 1.544–1.553 and birefringence 0.009; pleochroism is weak and varies with colour, treatment state: untreated; and the quality factor (lustre) is vitreous, treatment state: untreated. The items for structure, hardness, cleavage, density, optic character, refractive index, birefringence, pleochroism and lustre are all written by the cited clauses for synthetic quartz (the whole class), not measured on Synthetic Green Quartz separately.
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”.
Chemical composition, long-wave UV luminescence, short-wave UV luminescence, UV-visible spectrum, infrared spectrum, magnification: these whole-class features are given in the cited clause for synthetic quartz (the whole class), so they are not repeated on the Synthetic Green Quartz page; see the material facts on the Synthetic Quartz entry.
Items below that name the class they cover give the cited clause’s value for that whole class, not a measurement of Synthetic Green Quartz (how to read class-level values).

Who maintains this page
The material facts in the Synthetic Green Quartz entry are maintained by the LumaLark wiki and matched one by one to the standard clauses or institutional sources they cite: every fact carries its source (with a clause or page locator) and a check date, so it can be traced back to the original; clause-level definitions also carry a cross-check result. The entry exists so that buyers and sellers can check naming, disclosure and material facts item by item.
