The facts
What star Rose Quartz actually is
Star Rose Quartz is classified as quartz, with the composition SiO₂. It crystallises in the trigonal system.
Colour comes from rutile-like fibrous inclusions producing a six-rayed star plus body colour from fibrous inclusions, which is also what a laboratory looks at when it is asked whether a colour is natural.
Refractive index 1.544–1.553. Specific gravity around 2.65. Cleavage: none. Those three numbers separate it from most of what imitates it.
Where star Rose Quartz comes from
Star Rose Quartz is produced at Galileia, Minas Gerais, Brazil and Sakavalana, Madagascar.
The locality is part of the description, not a footnote — two stones of the same weight from two of these places are not the same stone.
How star Rose Quartz is treated
Untreated. The star is a natural inclusion effect and is best seen with transmitted light behind the cabochon.
Treatment changes value, sometimes by a multiple, so it belongs in the description before the price and not after the sale.
What star Rose Quartz is confused with
In the trade star Rose Quartz is most often mistaken for, or substituted by, Star quartz (colourless), Assembled star doublets or Diffusion-treated star sapphire (unrelated).
The separation is rarely a matter of opinion: refractive index 1.544–1.553 and specific gravity 2.65 settle most of it in a minute, and magnification settles the rest.
What star Rose Quartz is used for
Demand for star Rose Quartz comes from jewellery, mineral collecting and decorative objects, which is why one price per carat never covers it.
We quote each application in the unit that trade actually buys in, by the carat, by the specimen or by the piece.
Durability and care
Star Rose Quartz is 7 on the Mohs scale, with none cleavage.
With no cleavage plane to worry about, the practical limit is abrasion rather than breakage, and it takes daily wear well.
Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.
What star Rose Quartz costs
As a guide, star Rose Quartz trades around $2–25/ct.
That is a range, not a quote. Colour, size, clarity, cut and origin move the figure a long way inside it, and the only honest price is one given against a specific stone. Send us what you need and we will price it.
Questions
Is star Rose Quartz treated, and how?
Untreated. The star is a natural inclusion effect and is best seen with transmitted light behind the cabochon.
Where does star Rose Quartz come from?
Galileia, Minas Gerais, Brazil and Sakavalana, Madagascar. Origin affects price, so we name the locality rather than the country on every quote.
Is star Rose Quartz hard enough to wear every day?
Yes. At 7 on the Mohs scale with no cleavage plane, it handles daily wear well. The practical limit is gradual abrasion rather than chipping.
How much does star Rose Quartz cost?
Indicatively $2–25/ct. Colour, size, clarity and origin move the price a long way within that, so treat it as a range and ask for a quote against a specific stone.
What is star Rose Quartz confused with?
Most often Star quartz (colourless), Assembled star doublets and Diffusion-treated star sapphire (unrelated). A refractive index of 1.544–1.553 and a specific gravity near 2.65 separate it quickly.
What is star Rose Quartz used for besides jewellery?
mineral collecting and decorative objects. Each of those trades buys it in a different form and a different unit.
