Citrine

What is citrine?

Citrine is a mineral variety with chemical formula SiO₂. It has a Mohs hardness of 7, density of approximately 2.56–2.66 g/cm³, and refractive index of 1.54–1.55.

What gives it its color?

Iron (Fe²⁺) or color centers; much commercial citrine is heat-treated amethyst

Where does it come from?

Major sources include Brazil, Madagascar, USA, Russia, Spain.

Treatments and how to spot them

Most commercial citrine is heat-treated amethyst or smoky quartz. Natural citrine is rare and usually paler yellow.

Important: Visual clues such as inclusions, color patterns, or surface features can provide preliminary observations, but they cannot replace refractive index, specific gravity, microscopic examination, and laboratory testing for a definitive identification. Treat visual clues as starting points, not final answers.

Jewelry and care tips

With hardness 7, citrine is suitable for rings, pendants, earrings, and bracelets. Clean with warm soapy water and a soft cloth. Avoid ultrasonic cleaners unless the stone is known to be fracture-free. Store separately from harder gemstones.

Some citrine can fade or shift color after prolonged strong light or heat, and stability can vary with treatment history. Brief daily wear is different from long-term window or hot-car exposure; see does citrine fade in sunlight? for practical storage guidance.

Cultural beliefs and symbolism

Citrine carries cultural meaning across many traditions — these are folkloric and cultural traditions, not scientifically verified properties. Its associations vary by culture, and its use in astrology, chakra, or feng shui contexts should be understood as cultural expression rather than factual claims.

What affects its value?

Price is determined by color saturation, clarity, cut quality, and size. Before buying: ask the seller to confirm the material identity, treatment status, dimensions, and return policy in writing.
