Synthetic Beryl
Synthetically made beryl, matching natural Beryl in composition; GB/T 16552-2017 Annex A Table A.4 lists it as "synthetic beryl". 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 beryl is beryl, Be3Al2Si6O18, that human hands have crystallised in a laboratory instead of its arising through natural geological processes. CIBJO calls a synthetic stone an artificial product whose chemical composition, physical properties and structure match the natural counterpart's essentially; synthetic beryl accordingly reproduces the structure and composition of natural beryl. Production relies on controlled crystal-growth techniques in the laboratory — flux or molten-solution growth, or hydrothermal growth — carried out in vessels held at controlled temperature and pressure, bypassing the granitic-pegmatite or metamorphic-hydrothermal ore-forming processes that natural beryl requires.
Scope: Applies to explaining the artificially grown nature of synthetic beryl and its naming and disclosure boundaries; not used to describe the genetic details of any natural beryl deposit.
Sources CIBJO Gemstone Book 2022 · GIA Emerald Description
Where it forms
Controlled laboratory environment: artificial crystal growth in sealed vessels under controlled temperature and pressure, not a natural geological setting.
Sources CIBJO Gemstone Book 2022 · GIA Emerald Description
Growth medium: a molten flux/high-temperature solution, or a hydrothermal fluid, supplying the Be, Al and Si components and any colouring elements.
Sources CIBJO Gemstone Book 2022 · GIA Emerald Description
How it forms, step by step
Prepare Be-, Al- and Si-bearing feedstock (e.g. oxides or salts), adding colouring elements for the intended colour.
Sources GIA Emerald Description
Under controlled temperature and pressure, beryl nucleates and grows in a vessel by solution-growth techniques such as the flux (molten-salt) method or hydrothermal growth.
Sources GIA Emerald Description
After growth the crystal is cooled/annealed slowly, yielding a synthetic crystal with essentially the same composition and structure as natural beryl.
Sources GIA Emerald Description
The whole process is man-made with no natural ore formation; the product must be named and disclosed as e.g. 'synthetic beryl'.
Sources GIA Emerald Description
Link to appearance
Its chemical composition, physical properties and structure being essentially those of natural beryl, synthetic beryl looks essentially the same; man-made growth features, however, may be visible, including growth striations, flux residues or hydrothermal "nailhead" inclusions.
Sources CIBJO Gemstone Book 2022 · GIA Emerald Description
Timescale
The selected authorities give no growth duration for synthetic beryl; laboratory growth is typically on the order of days to weeks, but that level of detail is not stated by the sources.

Supporting findings
In their chemical, physical and optical properties, synthetic gemstones match their natural equivalents essentially; the difference is that a laboratory grows them, whereas natural mineralisation forms the natural ones.
Evidence grade AScope: A general-principle statement, not tied to a single growth method or producer.
Sources GIA Emerald Description
How it is identified
Synthetic beryl (emerald) can be extremely close to natural emerald in appearance, which cannot settle its identity. Identification is a laboratory task: immersion microscopy of internal inclusions and growth zoning is combined with chemical analysis that detects flux or other synthesis residues, in order to separate natural, synthetic and treated material; the verdict must come from an accredited body.
Evidence grade AScope: Synthetic beryl determinations require an accredited laboratory; no do-it-yourself method is offered.
Sources G&G Winter 2016
Synthetic beryl, including synthetic emerald, is man-made beryl. Such material is man-made, so natural origin determination does not apply. Origin determination is meaningful only for natural stones: for synthetic material the synthesis or treatment status has to be settled first, and a place name attached to it is at most a brand or a place of manufacture, not a geological source. Any separation of species or naturalness must be issued by a qualified laboratory for a specific specimen, and origin cannot be inferred from appearance or name.
Evidence grade AScope: Origin cannot be inferred from appearance or name; an origin conclusion must be issued by a qualified laboratory for a specific specimen, and this entry provides no self-test criteria or thresholds.
Other research findings
CIBJO defines a synthetic stone as an artificial product whose chemical composition, physical properties and structure match those of its natural counterpart essentially; synthetic beryl is defined along these lines.
Evidence grade AScope: The definition is classificatory/naming-level and does not describe any specific growth process.
Sources CIBJO Gemstone Book 2022
A synthetic stone shall be described by the correct natural-counterpart name immediately preceded by 'synthetic', 'laboratory-grown' or 'laboratory-created'; synthetic beryl must carry that prefix and not omit it.
Evidence grade AScope: A naming and disclosure rule; it does not address authenticity testing or provenance.
Sources CIBJO Gemstone Book 2022
The chemical composition of beryl (including synthetic beryl) is Be3Al2Si6O18.
Evidence grade AScope: Ideal formula only; excludes trace chromophores and inclusions.

What it is and how it's identified
The basic facts registered for Synthetic Beryl from GB/T 16553—2017 include: the chemical formula is Be3Al2Si6O18, and Mn, Fe, Ni, Cu, Zn, Ga and Rb may be present, with red material also carrying Ti and Cr; the structure is crystalline, hexagonal, with flux-grown crystals forming hexagonal prisms and hydrothermal crystals forming tablets. For durability, Mohs hardness is 7.5–8 with one direction of imperfect cleavage; this site notes that hardness alone is not enough to judge durability. Density is 2.65–2.73 g/cm³. Optically, the optic character is anisotropic, uniaxial, negative; refractive index is 1.568–1.572 and birefringence 0.004–0.006; this site notes that refractive index and birefringence are the usual typical values given by the cited clause, not absolute limits, and that refractive index has finer sub-ranges, with the overall value taken for registration. When untreated, Synthetic Beryl has a vitreous lustre.

Who maintains this page
The material facts in the Synthetic Beryl 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.
