Somehow this Tiffany Stone's photo came out more blue than purple, but purple it actually is! It has a projectile cut and two sealed drusy areas on the left that are harder than the rest of the cab (there is some slight undercutting around the lower area but not bad). The back is not polished.

Dimensions: 44mm x 21.5mm x 4mm.  Weight: 28.80 carats.

This cabochon is in my personal collection; it is not available for sale.
