An antique solid 14 carat gold (tests thereabouts) probably Russian trefoil brooch; beautifully made, with three demantoid garnet 'petals' around a tiny ruby. These test as garnets but are possibly doublets?
Terrific quality, so collectible & ready to wear!
CONDITION: All original and very, very good. Slightest signs of wear & abrasions to stones commensurate with age and use. May benefit from a clean.
