Rose Quartz
Everything you need to know about rose quartz: what it is, where it comes from, how to spot treated stones, and how to wear and care for it.
Note: Also called pink quartz or hibiscus stone (). Not to be confused with rhodonite or shoushan stone.

What is rose quartz?
Rose Quartz is a mineral variety with chemical formula SiO₂. It has a Mohs hardness of 7, density of approximately 2.65 g/cm³, and refractive index of 1.54–1.55.
What gives it its color?
The exact cause of rose quartz's pink color has been debated by mineralogists for decades, but recent studies indicate it is primarily caused by microscopic fibrous inclusions related to dumortierite, which contain trace amounts of iron and titanium. In rare cases, such as massive rose quartz and the crystalline pink quartz variety, color may also be influenced by irradiation and trace aluminum or phosphorus.
Where does it come from?
Major sources include Brazil, Madagascar, South Dakota (USA), China (Xinjiang, Yunnan).
Treatments and how to spot them
Dyed imitations common; color may fade under prolonged sunlight. Star rose quartz contains rutile needles.
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, rose quartz 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.
Cultural beliefs and symbolism
Rose Quartz 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.
Use this guide as a starting point
For a costly or disputed stone, ask for species, treatment, and origin information in writing. An independent laboratory report is stronger evidence than a marketing phrase.
