Egor have recently cut me from a large rock.
My weight is 19.63 ct, I'm colorless and sparkly!
Who am I? :wink:

Hint 1: you won't find me set in jewelry!

Good shot! Phenakite can have very similar appearance due to similar RI (hint 3)
But I'm much softer!... (hint 4) :D

Halite? But that's a mineral, not a rock. I can't think of any transparent rocks.

Oh, sorry, of course I'm a mineral... :oops: I've said "rock" because it was a large stone!...
But I'm not halite (see hint 3).

Now, that's impossible with you guys, I had so many good hints prepared and you've already got it! :( :) :)

Ok Marc, the big prize is for you!

That baryte comes from Spain, BTW!

The stone is so cool, I took the liberty of adding a Barite page to the Gemology Project.
Please feel free to add some more information to it.....

Oh, thank you Barbra! :smt042
It's a honor for me and for the stone!

Now, regarding the description as "rarely used in jewelry because of it's relative softness...", I would be more categorical. Hardness 3-3-5 is VERY low for faceted stone + perfect cleavage...
It's very tricky for faceting and unthinkable for jewelry, I'd say... Only collection gem.

Also, curious fact about its name that comes from its VERY high specific gravity...
It was one of my unused hints... :evil:
