Is This Citrine?

A yellow or orange transparent stone is citrine if it measures Mohs 7 hardness, refractive index 1.544–1.553, and specific gravity 2.651. Both natural-color and heat-treated citrine are genuine quartz — the difference is how the color arrived, not whether the stone is real.

What Numbers Define Citrine?

Three measurable values pin down citrine's identity. The International Gem Society lists citrine at Mohs hardness 7. Refractive index: 1.544–1.553. Specific gravity: 2.651. Any transparent yellow-to-orange quartz hitting all three readings is citrine.

Mohs 7 puts citrine above the hard surfaces a bracelet meets during daily wear. Citrine does not scratch from routine contact. A gemologist confirms refractive index with a refractometer and specific gravity with a hydrostatic balance; without those instruments, a scratch test gives partial confirmation — a real citrine bead scores glass while the bead stays unmarked.

Is Heat-Treated Citrine Still Real?

Heat-treated citrine passes every standard gemological test. Hardness stays at Mohs 7. Refractive index and specific gravity match citrine's published values. A stone that began as amethyst or smoky quartz and was heated until yellow still qualifies as citrine by mineral classification.

The practical difference is color stability. The International Gem Society notes that heat-treated citrine may fade when exposed to heat — sustained sun on a car dashboard or a jeweler's torch during repair. Keep a heat-treated citrine bracelet away from concentrated heat and the color stays put.

Why Do People Call Citrine the Merchant's Stone?

In crystal lore, citrine is traditionally called the merchant's stone — a talisman associated with prosperity and sunny self-belief. Many bracelet buyers choose citrine for that association rather than for gemological numbers.

The lore follows the mineral, not the thermal history. A heat-treated citrine carries the same traditional meaning as a natural-color citrine. Whether someone picks citrine for Mohs 7 durability or for the merchant's-stone tradition, the identity test is the same three values.

What Does a Citrine Bracelet Cost in 2026?

Citrine sits in the accessible segment of a large market. The USGS Mineral Commodity Summaries (February 2026) puts U.S. apparent gemstone consumption at $9.3 billion in 2025 — citrine bracelets occupy a small, affordable slice of that figure.

For specific benchmarks: Dusk & Citrine (10–11.5 mm, $95) pairs citrine beads with amethyst and phantom quartz. Sunstruck (8 mm, $115) uses raw citrine nuggets alongside clear quartz — the higher price reflects irregular-cut material. Happiness Is (11 mm, $95) blends citrine with several other stones, making citrine an accent rather than the lead.

I'd pick the 10–11.5 mm bead size if the goal is citrine color visible from across a table, because lighter citrine at 8 mm can read almost clear on some skin tones.

FAQ

How can I tell if my citrine is heat-treated?

Without a gemological lab, the most accessible indicator is heat sensitivity. Heat-treated citrine may fade if exposed to sustained high heat. The International Gem Society's fading caution applies to heat-treated stones specifically. A gemological lab can test for treatment markers through spectroscopy, but the stone remains citrine either way.

Can I wear a citrine bracelet every day?

Citrine's Mohs hardness of 7 makes daily wear practical. Citrine resists scratches from the surfaces a wrist encounters throughout the day. The one precaution for heat-treated citrine is avoiding prolonged heat exposure, which may shift the color over time.

Does sunlight fade citrine?

The International Gem Society caution is about heat, not light alone. Sustained high temperatures can fade heat-treated citrine. Brief outdoor sun during normal wear is different from leaving a bracelet on a car dashboard in summer, where enclosed heat builds up.

What does 'merchant's stone' mean?

In crystal lore, citrine is traditionally called the merchant's stone, a talisman associated with prosperity and sunny self-belief. The name is a folk tradition, not a gemological classification. The lore meaning stays the same regardless of whether the stone's color is natural or heat-treated.

What bead size works best for a citrine bracelet?

Bead size controls how much citrine color shows on the wrist. At 8 mm, lighter citrines can appear nearly translucent. Beads at 10–11.5 mm show the yellow-to-orange tone more distinctly. The right size depends on wrist circumference and how prominent the stone's color should read.

Is citrine the same as yellow quartz?

Citrine is a variety of quartz, so all citrine is quartz. But not every yellow-tinted quartz qualifies as citrine. Citrine's published properties — refractive index 1.544–1.553 and specific gravity 2.651, backed by Mohs hardness 7 — define the variety. A yellow quartz falling outside those ranges would be classified differently.

Why do citrine bracelet prices vary?

Price depends on bead size and cut style. A bracelet with raw citrine nuggets costs more to produce than one using machine-polished rounds. Multi-stone bracelets that include citrine alongside several other stones may cost less per bead because the design spreads across different materials.
