Untreated Freeform Hebei turquoise cabochon loose blue/green and brown gemstone

A piece of untreated Hebei turquoise.
 
This piece is freeform as a long oval organic shape, the piece lends itself to being a large bold cocktail ring, a gem for a bangle or even better as a sleek pendant due to the length. 
 
The blue/green area is the turquoise and the brown is the natural matrix of the gem which is how the gem grows, the dark base of the gem gives compliment to the lagoon blue colour of the turquoise.
 
Untreated gem material.
