Are my carnelian and citrine beads real or fake?
Citrine reference values overlap with clear quartz, so matching readings do not establish identity. See what the supplied evidence can tell you.
The supplied evidence cannot establish whether your particular carnelian or citrine beads are real or fake. Published citrine values overlap with clear quartz, while these references provide no carnelian identification values.

What can these checks tell you at a glance?
| Check | Supported reference | What remains unresolved |
|---|---|---|
| Specific gravity | Citrine and clear quartz both have a published value of 2.651 | A matching value does not distinguish them |
| Refractive index | Citrine and clear quartz both have a published range of 1.544–1.553 | A matching range does not distinguish them |
| Mohs hardness | Citrine and clear quartz both have hardness 7 | This value does not distinguish them |
| Fading after heat | Heat-treated citrine may fade when exposed to heat | This caution does not establish treatment history or identify a simulant |
| Carnelian identification | No identification values are supplied here | These excerpts cannot provide a carnelian pass/fail test |
| Seller's material label | A listing states the seller's material description | The description is not a measurement of your bead |
What does the evidence say about gemstone substitutes?
The USGS Mineral Commodity Summaries lists glass, plastics and other materials as substitutes for natural gemstones. The same report notes that simulants are frequently substituted for natural gemstones.
These statements cover gemstones in general. They do not establish how frequently glass or plastic is used for carnelian or citrine beads, and they do not identify the material of your beads.
What are the published citrine reference values?
The International Gem Society lists citrine's specific gravity as 2.651, refractive index as 1.544–1.553 and Mohs hardness as 7.
Matching these numbers does not distinguish citrine from clear quartz. The International Gem Society lists clear quartz (rock crystal) with the same specific gravity of 2.651, refractive index of 1.544–1.553 and Mohs hardness of 7. These published values are not test results for a particular bracelet.
For example, Sunstruck ($115) lists "Citrine / Lemon Quartz (raw nugget)" and clear quartz among its materials. That combined material label should not be resolved by assumption: the supplied citrine reference values do not supply values for lemon quartz or predict readings for this product's beads.
Does fading reveal whether citrine is treated or fake?
The supplied heat caution does not diagnose treatment or authenticity. The International Gem Society says heat-treated citrine may fade when exposed to heat; it does not say that fading establishes treatment, or describe whether untreated citrine can fade.
Ask the seller about treatment history rather than using fading as a test. For a mixed-material listing such as Happiness Is ($95), which includes citrine, ask specifically about the listed citrine's treatment.
What can these sources establish about carnelian?
These excerpts provide no carnelian density, refractive index or hardness values, so this article cannot offer a carnelian pass/fail number. That gap in the supplied evidence does not establish that carnelian is inherently harder to verify.
For related reading, see carnelian versus citrine authentication and telling whether a carnelian bracelet is real.
If you plan to clean or soak a carnelian strand while inspecting it, first check whether carnelian can safely go in water.
What should you ask about a bracelet listing?
Ask the seller to clarify material labels and treatment history rather than treating a listing as an identification result.
Sunstruck's "Citrine / Lemon Quartz (raw nugget)" label warrants clarification. Happiness Is lists citrine and clear quartz among its materials. Golden Thread ($115) lists gold rutilated quartz, which is not covered by the supplied citrine identification values.
Keep the seller's description separate from measurements of the actual beads.
FAQ
Can a scratch test prove my citrine bead is real?
The supplied hardness values cannot establish that. Citrine and clear quartz both have a published Mohs hardness of 7, so that value does not distinguish them.
If my citrine and clear quartz beads give the same density reading, is something wrong?
The International Gem Society lists the same specific gravity, 2.651, for citrine and clear quartz. A matching reading does not distinguish them or establish the identity of your particular beads.
My citrine bracelet faded after sitting near heat. Is it fake?
The supplied evidence does not establish that. The International Gem Society says heat-treated citrine may fade when exposed to heat. This is a heat caution, not a diagnostic test for treatment or a glass or plastic substitute.
Are glass and plastic beads really sold as gemstones?
The USGS lists glass and plastics among substitutes for natural gemstones and says simulants are frequently substituted for natural gemstones. That evidence concerns gemstones generally, not beads or carnelian and citrine specifically.
Can I judge carnelian by its orange color?
The supplied references give no carnelian identification data and do not support an orange-color authenticity test.
