Rutilated Quartz
Also known asGolden rutilated quartz (conditional name) · hair quartz (not to be used as a name)
Quartz containing rutile inclusions. GB/T 16552-2017 Table A.1 lists "rutilated quartz" by name, but the name only describes the needle-like look; whether the needles are rutile still needs confirming. 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
Rutiliated quartz ('hair quartz') is quartz (SiO2) that trapped needle- or hair-like mineral inclusions as it grew. Natural quartz crystals commonly crystallize inward from the walls of open cavities (vugs) out of silica-rich fluid, and needle inclusions are enclosed during that growth stage; primary inclusions are commonly found along growth layers and elongate along the direction of crystal growth, producing the visible 'hair' appearance. The type, orientation and density of the inclusions determine the final appearance.
Scope: Covers "hair crystal" materials formed by acicular/hair-like inclusions trapped during growth in natural quartz; does not cover fake material that has been artificially filled or coated.
Sources G&G Fall 2024 · G&G Spring 2017
Where it forms
Open cavities/vugs where quartz crystals grow inward from the walls out of silica-rich fluid
Sources G&G Spring 2017 · G&G Fall 2024
A quartz growth system coexisting with needle-forming minerals, whose needles are trapped by the quartz
Sources G&G Fall 2024
How it forms, step by step
Silica-rich fluid enters a cavity/vug and quartz crystallizes inward from the wall
Needle-like minerals coexisting with the quartz form in the growth system
During growth the quartz traps the needle minerals, and primary inclusions are found along growth layers and elongate along the growth direction
Later fluid activity can modify the crystal along growth defects (etching, dissolution), affecting inclusions and appearance
Link to appearance
The type, thickness, orientation and density of the needle inclusions govern the 'hair' appearance and its directionality; the refractive-index contrast between inclusions and the quartz host makes them clearly visible in transmitted light.
Sources G&G Fall 2024
Timescale
The cited authoritative texts give no specific duration for quartz or inclusion growth; they describe inclusion entrapment only in terms of a growth stage.

- Quartz (SiO2): Host mineral: rutilated quartz is quartz containing needle-like/hair-like mineral inclusions
Supporting findings
Primary inclusions in quartz are trapped during crystal growth and are commonly found along growth layers and elongate along the direction of crystal growth — the formation mechanism of the needle-like 'hair' inclusions in rutilated quartz.
Evidence grade AScope: The source is a Canadian La Manche amethyst (a quartz variety) case study; its inclusion-trapping mechanism is analogous to other quartz with needle inclusions, though the source does not name rutile.
Natural quartz crystals commonly crystallize inward from the walls of open cavities (vugs) in rock or volcanic rock out of silica-rich fluid.
Evidence grade AScope: The source describes quartz clusters in vugs of the Deccan Trap basalts of India; it is an example, not a locality specific to rutilated quartz.
Conditions during quartz growth, such as impurity incorporation and growth rate, can influence its internal structure/defects, and thereby the later alteration of the crystal by fluids.
Evidence grade BScope: The source concerns Brazil twin-boundary defects in quartz (linked to iridescence), not inclusions as such; here it only shows that growth conditions affect internal structure.
Recorded localities
Authoritative sources list the localities below; the list is not exhaustive.
South America
- Remédios, Novo Horizonte, Bahia, BrazilGolden rutilated quartz; not described as the only or 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 how far testing can go on this page, the origin determination guide and the overview of recorded localities.
Other research findings
Quartz can host various coexisting mineral inclusions (including needle/hair-like ones), and mineral inclusions are often most abundant during particular growth stages.
Evidence grade BScope: The source's examples are from amethyst quartz (hematite, goethite, sulfides, etc.); this shows quartz can host needle inclusions but does not mean all rutilated-quartz inclusions are rutile.
Limits of this research
- Research status: Formation, occurrence or other material-specific findings found in authoritative sources
- The G6-assigned text (a study of iridescent quartz) does not address rutile inclusions; identifying the included mineral in rutilated quartz requires other authoritative sources and is not asserted here.
- The inclusion-trapping mechanism is drawn by analogy from an amethyst (quartz variety) case study and does not sample all types of rutilated quartz.

Each CIBJO value links to its entry under “Testing and market”, where the wording and source are given in full.

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.

Names
For Rutilated Quartz, "Golden rutilated quartz" is recorded with no restriction on use as a name, while "hair quartz" must not be used as a name (16 CFR Part 23 §23.26(a); CIBJO Gemstone Book 2022 §4.2.4.4; CIBJO Gemmological Laboratories Book 2024 §7.2.1.203; GB/T 16552—2017 §5.1.1 c)); one further name in a non-Latin script is listed in the name register below (1 with no restriction recorded on use as a name).
Chinese standard nameThe Chinese formal name for Rutilated Quartz comes from GB/T 16552—2017 Table A.1, and the mineralogical name is quartz containing rutile inclusions. Names in four languagesNames are given in Simplified Chinese, Traditional Chinese, English (Rutilated Quartz) and Japanese. Recommended listing nameThe suggested listing name is rutilated quartz; where rutile has not been confirmed, use quartz (with needle-like inclusions) instead. Sub-names and unacceptable namesAmong trade names or synonyms, Golden rutilated quartz is a search candidate only; hair quartz is a market name and not a usable name: GB/T, CIBJO and GIA have no name hair quartz, and hair quartz does not say which inclusion mineral is present, so it is kept as a search term only. Institution usageOn authority wording, CIBJO Gemmological Laboratories Book 2024 lists Rutilated Quartz; the FTC text contains no wording for Rutilated Quartz (checked); GIA and Gem-A are unchecked, and bodies without a recorded wording show the entry's own English name, which does not represent their position. Japanese namesOn the GSJ (Japan) formal name, the entry has its own Japanese name, and the wording used by GSJ (Japan) for this name is not yet verified by this site. Candidate search termsThe JJA/AGL gem names handbook 2025 also registers a Japanese transliteration of "rutilated quartz", which is a search candidate only.

What it is and how it's identified
The composition (phase) of Rutilated Quartz is quartz, from CIBJO's entry for Rutilated quartz; structural, durability and optical data are registered by GB/T 16553—2017 for rock crystal as a whole class and are not measurements of Rutilated Quartz alone. For rock crystal as a whole: the material is crystalline, trigonal, with hexagonal prismatic crystals bearing pronounced horizontal striations, Mohs hardness 7, no cleavage, and density 2.64–2.69 g/cm³, the range derived from the clause value of 2.66 with a tolerance of +0.03/−0.02; refractive index is 1.544–1.553, birefringence 0.009, and optical character anisotropic, uniaxial positive; chatoyancy and six-rayed stars can be seen, the stars mostly in rose quartz; in the untreated state the quality factor (lustre) is vitreous. The host itself is colourless, light yellow or light brown; with rutile inclusions it often appears golden yellow or brownish red, with tourmaline greyish black, and with actinolite greyish green, as registered for the untreated state. This site also notes that in Chapter 5 of GB/T 16553—2017 the colour item for varieties such as sphalerite, garnet and diamond also mentions colourless.
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 Rutilated Quartz 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 Rutilated Quartz (how to read class-level values).

Who maintains this page
The material facts in the Rutilated 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.
