The facts
What goshenite actually is
The species behind goshenite is beryl, Be₃Al₂Si₆O₁₈; it forms in the hexagonal system.
On the instruments it reads a refractive index of 1.577–1.583 and a specific gravity of about 2.66–2.72, with imperfect, one direction cleavage.
Where goshenite comes from
Commercial material comes from Goshen, Massachusetts, USA, Minas Gerais, Brazil and Pakistan.
Different localities give different colour and different clarity, and the trade prices them differently. We state which one.
Is goshenite treated?
None normally.
Nothing needs disclosing, and nothing about the stone can change after you buy it. If a price looks impossible, the risk is substitution rather than treatment.
What goshenite is confused with
Watch for White sapphire, Danburite and Rock crystal — these are what turn up sold under this name.
The separation is rarely a matter of opinion: refractive index 1.577–1.583 and specific gravity 2.66–2.72 settle most of it in a minute, and magnification settles the rest.
What goshenite is used for
The trades that buy goshenite are jewellery. They do not want the same thing, and they do not pay in the same unit.
We quote each application in the unit that trade actually buys in, by the carat.
Durability and care
Goshenite is 7.5–8 on the Mohs scale, with imperfect, one direction 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 goshenite costs
Expect roughly $10–60/ct, depending on quality.
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 goshenite treated?
None normally.
Where does goshenite come from?
Goshen, Massachusetts, USA, Minas Gerais, Brazil and Pakistan. Origin affects price, so we name the locality rather than the country on every quote.
Is goshenite hard enough to wear every day?
With care. It is 7.5–8 on the Mohs scale, which is hard enough, but imperfect, one direction cleavage means it can split if struck at the wrong angle. Use a protective setting and avoid ultrasonic cleaning.
How much does goshenite cost?
Indicatively $10–60/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 goshenite confused with?
Most often White sapphire, Danburite and Rock crystal. A refractive index of 1.577–1.583 and a specific gravity near 2.66–2.72 separate it quickly.
