Condition:
Sapphire an attractive colour, and nice cut, with surface-reaching fissure towards one edge going through stone. Safe and secure in mount, but stone has not been unmounted so we are unable to assess its durability. Diamonds bright and lively, likely an earlier centre, perhaps originally a ring, within a later frame. Gross weight approximately 8 grams.
