Quartz with golden needle-like inclusions
Also known asGolden hair quartz · golden rutilated quartz (conditional name)
Quartz with golden needle-like inclusions; whether the inclusions are rutile must be confirmed by testing, and synthetics or treatments such as dyeing or filling must be disclosed. Also known as Golden hair quartz, golden rutilated quartz. 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
Golden-hair quartz (golden rutilated quartz) is a market name for quartz (SiO2) hosting golden, needle-like inclusions; the golden needles are inclusions captured during crystal growth, not a distinct mineral species. The quartz host precipitates slowly from silica-bearing fluids in open cavities or vein pockets, and the crystals grow as short-prismatic points facing into the cavity. Inclusions are trapped during growth, commonly along growth layers and elongated in the direction of crystal growth. The inclusions may be needle-like mineral crystals or complex multi-component fluids (as in the Madagascar quartz with petroleum, methane, asphaltite, and water). The needle-like inclusions are the 'hair' of the trade, but the inclusion mineral species requires identification case by case.
Scope: Applies to explaining the crystallisation and inclusion-trapping mechanism of quartz containing golden needle-like inclusions (market names of the 'golden rutilated quartz' type); not specific to any one determined mineral species, and does not cover the origin of synthetic or filled material.

- Quartz (SiO2): inclusion-bearing-quartz-of | This type of material is quartz containing inclusions, attached to the mineral species quartz, not an independent mineral species
Supporting findings
Quartz hosting needle-like inclusions grows into open cavities as short-prismatic crystals facing the cavity interior.
Evidence grade AScope: Crystal habit and cavity growth are based on observations of natural included quartz in open-system settings.
The needle-like inclusions of golden-hair quartz are primary inclusions trapped during crystal growth, commonly along growth layers and elongated in the growth direction.
Evidence grade AScope: Concerns the trapping mechanism; does not assert a specific inclusion mineral species.
Quartz with golden needle-like inclusions is supplied from the Remedios area of Novo Horizonte, Bahia State, Brazil, as a distinctive locality.
Evidence grade BScope: Single-locality report (GIA Gem News note); not representative of all sources.
Recorded localities
Authoritative sources list the localities below; the list is not exhaustive.
South America
- Remédios, Novo Horizonte, Bahia, BrazilArtisanal golden rutilated quartz mining community in Bahia; not stated as the main source
These are localities recorded by authoritative sources, not an origin finding for any individual piece. The CIBJO Gemstone Book (2022, §4.2.3) says a place of origin names where a gem was mined or harvested, is a matter of opinion, does not imply a level of quality, and that cutting, processing or exporting centres must not be used to imply origin. See the origin determination guide and the overview of recorded localities.
Other research findings
Golden-hair quartz is a market name for quartz with golden needle-like inclusions, not an independent mineral species; the exact inclusion species is not confirmed by the available authoritative sources and requires case-by-case testing.
Evidence grade CScope: Naming/identification boundary only; sources describe the trade material as 'golden rutilated quartz' without mineral-species confirmation.
Fluid inclusions in quartz can be trapped during crystal growth and may be multi-component (e.g., petroleum, methane, asphaltite and water in Madagascar quartz).
Evidence grade AScope: An example of quartz fluid-inclusion composition; it does not mean golden-hair needles are themselves fluid.
Limits of this research
- Research status: Formation, occurrence or other material-specific findings found in authoritative sources
- The available authoritative sources do not confirm the inclusion mineral species of golden-hair quartz; inclusion identity must be tested case by case.
- No growth duration or absolute age is given; 'golden-hair quartz' is a trade name, not a single mineral species.

Whether a treatment has to show in the name differs between the two rule sets (this site’s paraphrase):
- GB/T 16552—2017: a method classed as treatment has to be stated in the name itself — the method put before the name, or added in brackets after it; a method classed as optimization does not need to appear in the name, though one marked “Optimization (annotation required)” still has to be noted in the quality documents. Source: §5.4.2.1 a), b); §5.4.2.2 a)
- CIBJO Gemstone Book 2022: no longer splits treatments into ones that need specific disclosure and ones that need only general disclosure: every treatment is to be disclosed, and the seller tells the buyer which treatment was used and what special care it calls for.

Treatments listed by standards
For Quartz with golden needle-like inclusions, optimizations and treatments are checked against the "Rock Crystal" row of GB/T 16552—2017 Annex B, Table B.1: heating is an optimization, irradiation is an optimization, filling is graded, dyeing is a treatment and coating is a treatment. What Table B.1 is, and how the filling grades are defined, are on the Gem treatments page.

What it is and how it's identified
The registered material facts for Quartz with golden needle-like inclusions are values given in GB/T 16553—2017 Gems — Testing for rock crystal (the whole class), not measurements of this material itself; chemical composition, luminescence, UV-visible spectrum, infrared spectrum and magnification are on the Rock Crystal entry. Taking values for rock crystal (the whole class): structure crystalline, trigonal, with hexagonal prismatic crystals and horizontal striations on the prism faces; Mohs hardness 7, cleavage none; density 2.64–2.69 g/cm³, the clause value being 2.66 with stated tolerances of +0.03 and −0.02, from which the limits are derived. Also for rock crystal (the whole class): refractive index 1.544–1.553, birefringence 0.009, optic character anisotropic, uniaxial, positive; chatoyancy visible, and asterism visible and six-rayed; lustre vitreous, treatment state untreated.
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, luminescence, UV-visible spectrum, infrared spectrum, magnification: these whole-class features are given in the cited clause for rock crystal (the whole class), so they are not repeated on the Quartz with golden needle-like inclusions page; see the material facts on the Rock Crystal entry.
Items below that name the class they cover give the cited clause’s value for that whole class, not a measurement of Quartz with golden needle-like inclusions (how to read class-level values).
