Yellow tower-form quartz crystal
Also known asYellow Tower Crystal (not a recommended name) · Yellow Tower Quartz (not a recommended name)
A non-standard Chinese market name that only describes a yellow, tower-shaped appearance; it must not be classed as citrine or calcite without checking. Also known as Yellow Tower Quartz, Yellow Tower Crystal. 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
Huangtajing is a non-standard Chinese market name. The authoritative texts cited here give it no definition; it maps to no IMA-recognised mineral species and is not among the CIBJO Gemstone Book's Annex 8 names. Under CIBJO rules, all commercial names not listed in Annex 8, whether new or old, must be submitted for approval and inclusion, and otherwise shall be described by mineralogical or geological name only. Within the available authoritative sources, therefore, 'Huangtajing' has no verifiable mineralogical definition and does not constitute an identifiable material type; its mineral identity cannot be determined from the name. This entry flags that gap and does not assert an unproven equivalence to quartz/citrine or any other material.
Scope: Applies to explaining that 'Huangta' as a non-standard market name lacks an authoritative definition; not applicable to determining its mineral identity, origin, locality or value.
Sources CIBJO Gemstone Book 2022
Where it forms
The cited sources do not describe the occurrence of 'Huangtajing'; as its mineral identity is undetermined, no geological setting can be given.
Sources CIBJO Gemstone Book 2022
How it forms, step by step
Extract the market name (no verifiable mineral identity in the cited sources).
Sources CIBJO Gemstone Book 2022
Because the name maps to no IMA mineral species or CIBJO Annex 8 name, no formation process can be described from it.
Sources CIBJO Gemstone Book 2022
The actual material must be tested and then described by its mineralogical or geological name.
Sources CIBJO Gemstone Book 2022
Link to appearance
Appearance cannot substitute for identification; neither the market name nor appearance proves its mineral identity.
Sources CIBJO Gemstone Book 2022
Timescale
No authoritative source gives a formation duration or absolute age for 'Huangtajing'.
Sources CIBJO Gemstone Book 2022
Other research findings
'Huangtajing' is a non-standard Chinese market name; the cited authoritative texts give it no definition, and it maps to no IMA-recognised mineral species, so its mineral identity cannot be determined from the name.
Evidence grade CScope: A naming-boundary judgement; 'no authoritative definition' refers only to the cited sources and does not exclude a definition elsewhere.
Sources CIBJO Gemstone Book 2022
Under the CIBJO Gemstone Book, commercial names not listed in Annex 8, whether new or old, must be submitted for approval and inclusion, and shall otherwise be described by IMA mineralogical or geological name only; 'Huangtajing' does not constitute an identifiable material-type name.
Evidence grade BScope: Application of the naming rule; it makes no finding on what mineral 'Huangtajing' actually corresponds to.
Sources CIBJO Gemstone Book 2022
No authoritative source describing the mineral identity, formation or occurrence of 'Huangtajing' has been found, so its formation mechanism remains a gap.
Evidence grade CScope: Flags an evidence gap; it does not mean the mechanism is unknowable, only that no such source has been found.

Limits of this research
- Research status: No authoritative source specific to this material was found; findings come from the parent material or are marked as gaps
- 'Huangtajing' is a non-standard market name with no mineralogical definition in the reviewed authoritative texts and does not constitute an identifiable material type; the evidence for it is rated no higher than C.
- Not inferred from the name to be quartz/citrine or any mineral species.
- No authoritative source on the formation or occurrence of this name has been found, so formation content is left as a gap.

Names
Besides Yellow tower-form quartz crystal, the name register records "Yellow Tower Crystal" and "Yellow Tower Quartz", for which no restriction on use as a name is recorded.
Trade and mineralogical namesYellow tower-form quartz crystal is a trade name; the mineralogical name is a non-standard Chinese market name, and the name itself cannot establish mineral identity; no national-standard name correspondence is listed in the original, and the basic name must be determined by identification (GB/T 16552—2017). Recommended listing nameThe suggested listing name is Yellow tower-form quartz crystal (switch to the specific material name after testing). Trade and mineralogical namesThe market names Yellow Tower Crystal and Yellow Tower Quartz are not matched to this entry; they are listed as not to be used interchangeably, with the correspondence unproven. Names in four languagesNames are given in Simplified Chinese and Traditional Chinese; the English name is a non-standard market name for yellow tower-shaped quartz crystals, noting the Chinese trade name huangta and that the material is unverified; and the Japanese name describes it as a Chinese market name with undetermined material. Institution usageThe wording of GIA, FTC, CIBJO and Gem-A for this name is not yet verified by this site; the entry's own English name is shown and does not represent the position of GIA, FTC, CIBJO or Gem-A; the qualifier stripped from the title name is Chinese trade name huangta, material unverified, and it comes from the entry's own English name. Japanese namesJapan's GSJ wording for this name is not yet verified by this site, and the entry's own Japanese name is shown.

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. “Huangta jing” is a market name for the colour and tower shape only. No source consulted uses it, and none says whether it is quartz, calcite or another yellow material, so no material facts are listed. The name also does not appear in the gemmological journals consulted (Journal of Gems & Gemmology, Mineralogy and Petrology, Acta Petrologica et Mineralogica) or in GIA material (Gems & Gemology and Lab Notes); only sellers and self-published articles describe it as a kind of citrine, with no testing behind it, so they are not used.
