The facts
What mystic Topaz actually is
Mystic Topaz is classified as topaz, with the composition Al₂SiO₄(F,OH)₂ with a surface coating. It crystallises in the orthorhombic system.
Colour comes from not a colour at all — a thin-film metal-oxide coating applied to the pavilion by vapour deposition, which is also what a laboratory looks at when it is asked whether a colour is natural.
Refractive index 1.609–1.617 (host). Specific gravity around 3.53–3.59. Cleavage: perfect basal {001}. Those three numbers separate it from most of what imitates it.
Where mystic Topaz comes from
Mystic Topaz is produced at Brazil (host topaz); coating applied in the USA, India and elsewhere.
That is the whole list. A single source makes supply fragile and makes any claim of a second origin worth questioning.
How mystic Topaz is treated
Surface-coated colourless topaz. The coating is thin, scratches off, and is damaged by ultrasonic cleaning, repolishing, steam and some jewellery chemicals. It must be disclosed, and any repair work on a set stone risks destroying it. Visible under magnification as a film with scratches and iridescent patchiness on the pavilion.
Treatment changes value, sometimes by a multiple, so it belongs in the description before the price and not after the sale.
What mystic Topaz is confused with
In the trade mystic Topaz is most often mistaken for, or substituted by, Coated quartz ('aura' quartz), Ammolite, Natural bi-colour stones or Iridescent glass.
The separation is rarely a matter of opinion: refractive index 1.609–1.617 (host) and specific gravity 3.53–3.59 settle most of it in a minute, and magnification settles the rest.
What mystic Topaz is used for
Demand for mystic Topaz comes from jewellery, 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.
Durability and care
Mystic Topaz is 8 (coating far softer) on the Mohs scale, with perfect basal {001} cleavage.
Hardness is not the whole story. Perfect cleavage means the stone can split cleanly if struck along the wrong plane, whatever its Mohs number, so a protective setting matters more here than the hardness suggests.
Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.
What mystic Topaz costs
As a guide, mystic Topaz trades around $1–8/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 mystic Topaz treated, and how?
Surface-coated colourless topaz. The coating is thin, scratches off, and is damaged by ultrasonic cleaning, repolishing, steam and some jewellery chemicals. It must be disclosed, and any repair work on a set stone risks destroying it. Visible under magnification as a film with scratches and iridescent patchiness on the pavilion.
Where does mystic Topaz come from?
Brazil (host topaz); coating applied in the USA, India and elsewhere. That is the only commercial source.
Is mystic Topaz hard enough to wear every day?
With care. It is 8 (coating far softer) on the Mohs scale, which is hard enough, but perfect basal {001} cleavage means it can split if struck at the wrong angle. Use a protective setting and avoid ultrasonic cleaning.
How much does mystic Topaz cost?
Indicatively $1–8/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 mystic Topaz confused with?
Most often Coated quartz ('aura' quartz), Ammolite, Natural bi-colour stones and Iridescent glass. A refractive index of 1.609–1.617 (host) and a specific gravity near 3.53–3.59 separate it quickly.
