Blue Sapphire Cabs - Faceted Cushion Cuts
Midnight blue Sapphire cabs - faceted cushion cuts with varying depths to the stones.
Opaque material with natural inclusions - please see photos. I have no information on any treatments they may have had.
These could make interesting stacking rings or earrings perhaps?
7 x 7 x 3 mm - 7.3 x 7.3 x 4.4 mm approx.
