Smoky Quartz (brown variety)
Also known asbrown quartz
A Chinese trade colour name for the browner kinds of Smoky Quartz, usually lighter-toned Smoky Quartz; there is no unified standard for the boundary between light and dark. 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.
Questions people ask about Smoky Quartz (brown variety)
Every sentence below is followed by the registered fact it rests on; answers add no new facts and promise no outcome.
Q1What makes smoky or brown quartz brown?
The brown comes from aluminium-related colour centres activated by natural irradiation, the same mechanism as in smoky quartz.G&G Gem News International (Krzemnicki)How deep the brown is depends on the concentration of colour centres and the irradiation history, so smoky and brown quartz grade continuously into each other.G&G Gem News International (Krzemnicki)
Q2Is brown or tea quartz the same as smoky quartz?
Tea quartz is a trade colour name for brown quartz; like smoky quartz it is a variety of quartz, not a separate mineral, and the two differ in naming and depth of colour rather than in origin.G&G Gem News International (Krzemnicki)
Q3Can you tell natural smoky quartz from irradiated or fake material?
According to the parent entry Quartz, colour and appearance do not prove whether a quartz is natural or synthetic; that takes laboratory methods such as microscopy, EDXRF and infrared spectroscopy.G&G Summer 2014 · CIBJO Gemstone Book 2022 (via parent entry Quartz)Whether one particular bead is natural, treated or synthetic — only a laboratory report can settle that.What this page can answer
Q4Can smoky quartz lose its colour?
Yes, with heat: the parent entry Quartz notes that heat turns smoky quartz colourless.Gems & Gemology 1987 (Martin) (via parent entry Quartz)The same Quartz record rates sunlight and artificial light as relatively safe for transparent quartz other than amethyst and citrine.Gems & Gemology 1987 (Martin) (via parent entry Quartz)
Q5How does smoky quartz form?
Quartz crystallizes from silica-bearing fluid, with aluminium concentrating in certain growth zones.G&G Spring 1982 · G&G Spring 2017Natural irradiation of those aluminium-rich zones then forms colour centres that turn the quartz brown.G&G Gem News International (Krzemnicki)The crystals commonly grow inward from the walls of open cavities, forming clusters.G&G Spring 2017
Q6How should smoky quartz be cleaned and worn?
For transparent quartz, the parent entry Quartz records that ultrasonic and steam cleaning call for caution and thermal shock should be avoided.Gems & Gemology 1987 (Martin) (via parent entry Quartz)The Quartz record rates prong and bezel settings as relatively safe and flush, channel and pavé as best avoided.Gems & Gemology 1987 (Martin) (via parent entry Quartz)
Q7Is smoky quartz irradiated?
Often: CIBJO's treatment table lists smoky quartz as commonly irradiated, with a stable result, and untreated smoky quartz as rare.CIBJO Gemstone Book 2022
Q8Does smoky quartz have protective or healing powers?
There is no scientific evidence that smoky quartz has healing powers: the UK advertising regulators ASA and CAP state that they have not seen evidence that crystal therapy can treat medical conditions.ASA/CAP guidance (UK)

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
'Tea quartz' is a commercial colour name for brown quartz; it is not a separate mineral species and does not constitute an independent mode of origin. Its brown colour belongs to the same colour-centre mechanism as smoky quartz: during growth, aluminium impurities concentrate in certain growth sectors, and subsequent natural irradiation of these Al-rich zones forms Al-related colour centres that give the quartz a brown tone. The distinction from smoky quartz lies mainly in trade naming and colour depth, not in origin or mineral species.
Scope: Covers the cause of colour of brown quartz sold in the trade (cha jing) and its naming relationship to smoky quartz; does not cover synthetic, dyed or coated imitation material.
Sources G&G Gem News International (Krzemnicki) · G&G Spring 2017 · G&G Spring 1982
Where it forms
Hydrothermal quartz growth systems able to accommodate aluminium impurities.
Sources G&G Gem News International (Krzemnicki) · G&G Spring 1982
Natural background radiation: the Al-rich zones must be irradiated to develop the brown colour.
Sources G&G Gem News International (Krzemnicki)
Brown quartz occurs in the same kinds of quartz settings as other colour-centre varieties such as smoky quartz.
Sources G&G Gem News International (Krzemnicki)
How it forms, step by step
Silica-bearing fluid crystallizes quartz while growth conditions promote aluminium enrichment in particular growth sectors.
The crystal continues to grow, producing sector or zonal variation in aluminium.
Natural irradiation of the Al-rich zones forms Al-related colour centres, giving the quartz a brown colour.
Sources G&G Gem News International (Krzemnicki)
Material whose colour reads as brown is traded under the name 'tea quartz'.
Sources G&G Gem News International (Krzemnicki)
Link to appearance
Aluminium-related colour centres activated by natural irradiation give the brown hue traded as tea quartz; the depth of brown depends on colour-centre concentration and irradiation history, so smoky and tea quartz grade continuously in tone.
Sources G&G Gem News International (Krzemnicki)
Timescale
The source gives no absolute age or duration for tea quartz / brown quartz growth.
Sources G&G Spring 2017 · G&G Gem News International (Krzemnicki)
Related base materials
- Quartz (SiO2): colour-name-of | Brown smoky quartz is a commercial colour name for brown quartz
Supporting findings
Silica delivered by migrating solutions can accumulate slowly inside cavities and vesicles, depositing the hydrothermal quartz to which tea quartz belongs.
Evidence grade AScope: The source describes deposition of amethyst/citrine/green-quartz clusters; analogous to how the quartz host of tea quartz generally precipitates.
The quartz crystals to which tea quartz belongs commonly grow inward from the walls of open vugs out of silica-rich fluid, forming druses.
Evidence grade AScope: The source is a quartz druse in Deccan Trap basalt vugs, India; a general quartz occurrence setting.
Causes of colour and optical effects
The brown colour of brown quartz (tea quartz) is produced by Al-related colour centres activated by natural irradiation, the same class of mechanism as smoky quartz.
Evidence grade BScope: The source discusses smoky quartz layers and does not use the name 'tea quartz'; the mechanism is extended to brown quartz by analogy under the same colour-centre model.
Sources G&G Gem News International (Krzemnicki)
Other research findings
'Tea quartz' is a commercial colour name for brown quartz, a variety of quartz (SiO2) rather than a separate mineral; it and smoky quartz are both quartz, differing in naming and colour depth rather than origin.
Evidence grade CScope: The naming boundary is not defined directly by any authoritative source; it is organized from the varietal definition and the colour-centre mechanism.
Sources G&G Gem News International (Krzemnicki)
The CIBJO Gemstone Book's treatment table lists smoky quartz (also called cairngorm or brown quartz) as commonly irradiated, with the result classed as stable, and lists untreated smoky quartz as rare.
Evidence grade BScope: Reports how common a treatment is according to one trade nomenclature table; it says nothing about whether any particular piece has been treated, which only laboratory testing can establish.

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.
