Man-made strontium aluminate borate with no natural counterpart; GB/T 16552-2017 Annex A Table A.5 lists it as "man-made strontium aluminate borate". 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.

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 strontium boroaluminate is recorded by material name under the class 'artificial products with no natural counterpart'. Under CIBJO, an artificial product is a product partially or completely made by man, and an artificial stone is an artificial product with no natural counterparts; the name therefore denotes a man-made, not a mined, material. The cited authoritative sources (the CIBJO clauses) give only the general definition and naming rules for artificial products/stones; they provide no material-specific description, so the exact formulation, crystalline-versus-amorphous state, and synthesis route cannot be confirmed from the available sources.
Scope: Applies to explaining the category of artificial products to which this name belongs and its naming rules; does not apply to asserting its specific formulation, process or whether it is a particular mineral, and in no case concerns natural genesis.
Sources CIBJO Gemstone Book 2022
Where it forms
Manufacturing environment: as an artificial product its manufacture is a man-made setting, but the available authoritative sources do not state its specific manufacturing conditions.
Sources CIBJO Gemstone Book 2022
Not applicable to a natural occurrence environment: the name is treated as an artificial product with no natural counterpart, so no natural geologic environment is involved.
Sources CIBJO Gemstone Book 2022
How it forms, step by step
By material name it is placed in CIBJO's class of artificial products (products partially or completely made by man).
Sources CIBJO Gemstone Book 2022
As an artificial product with no natural counterpart, its naming must follow the artificial product/stone rules (its exact formulation, crystalline state, and synthesis route are not confirmed by the available authoritative sources).
Sources CIBJO Gemstone Book 2022
Finished product: used as a man-made material for jewelry or decorative purposes, it must be disclosed as an artificial product and not presented as a natural gemstone.
Sources CIBJO Gemstone Book 2022
Link to appearance
Appearance may suggest a color or that it is an artificial material, but appearance alone cannot prove its composition or identity; this record makes no claim about its specific appearance.
Sources CIBJO Gemstone Book 2022
Timescale
The available authoritative sources state no introduction date or process duration for this material.
Sources CIBJO Gemstone Book 2022
Other research findings
Under CIBJO, an artificial product is a product partially or completely made by man; an entry named 'Artificial Strontium Aluminate Borate' denotes a man-made material rather than a mined one.
Evidence grade AScope: Applies to the artificial-product class the name belongs to; not to its specific formulation or material identity.
Sources CIBJO Gemstone Book 2022
Under CIBJO, artificial stones are artificial products that have no natural counterparts; accordingly, this name must follow the artificial product/stone naming and disclosure rules.
Evidence grade AScope: Applies to naming and disclosure requirements; does not mean the material has been mineralogically identified.
Sources CIBJO Gemstone Book 2022
The authoritative sources cited here (the CIBJO clauses) give only the general definitions of artificial products and artificial stones and provide no material-specific description of 'Artificial Strontium Aluminate Borate'; its exact formulation and process cannot be confirmed from the cited sources.
Evidence grade CScope: Applies to stating the evidence gap; it is not a factual assertion about the material's composition or process.

Names
For Artificial Strontium Aluminate Borate, "glow in the dark stone" and "luminous stone" must not be used as a name (GB/T 16552—2017 Table A.5 “Strontium Aluminate Borate”; GB/T 16552—2017 §5.1.3.2 c); 16 CFR Part 23 §23.25(b)).
Standard and listing namesThe Chinese formal name for Artificial Strontium Aluminate Borate comes from GB/T 16552—2017 Table A.5, and the suggested listing name is Man-made Strontium Aluminate Borate. Names in four languagesThe four-language names cover Simplified Chinese, Traditional Chinese, English (Artificial Strontium Aluminate Borate) and Japanese. Trade and mineralogical namesThe mineralogical name is recorded as a man-made strontium aluminate borate material. Institution usageOn authority wording, CIBJO has it on record, marked as an artificial product, under the name Strontium Aluminate Borate; the FTC text on file has no wording for this name (checked), and GIA and Gem-A are unchecked; bodies without a record or not yet checked show the entry's own English name, which does not represent their position. Japanese namesThe GSJ (Japan) wording for the entry's own Japanese name is not yet verified by this site.

What it is and how it's identified
The material facts for Artificial Strontium Aluminate Borate are registered from GB/T 16553—2017: the general composition formula is M·N·Al2-xBxO4, where M stands for alkaline-earth metals such as Sr, Mg, Ca and Ba, N for rare earths such as Eu and Dy, and 0.1≤x≤1; the structure is a crystalline aggregate, commonly granular or massive. Mohs hardness is 6.5, there is no cleavage, density is 3.2–3.58 g/cm³, the optic character is an anisotropic aggregate, and birefringence cannot be measured on an aggregate. Refractive index is 1.65–1.68; this site notes that these are the readings commonly obtained by the spot method, typical values rather than absolute limits. Where the treatment state is untreated, pleochroism cannot be measured on an aggregate; body colour is light yellow, yellow, green, yellowish green, orange-red or purplish grey; lustre is vitreous; magnification shows gas bubbles and a granular structure; fluorescence is moderate to strong yellowish green under long-wave UV and moderate to strong yellow, bluish green or yellowish green with phosphorescence under short-wave UV. In the mid-infrared region the spectrum shows absorption bands characteristic of Strontium Aluminate Borate.

Who maintains this page
The material facts in the Artificial Strontium Aluminate Borate 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.
