This is an iconic style of vintage pendant. It is close set filigree with a center Garnet of @0.20 CT predominantly in 10 K white gold. The handsome bale is 18 K gold and a marriage no doubt. The pendant is 1 3/4" by 3/4" and weighs 2.0 grams.
It is in excellent estate condition and would be gorgeous on a velvet ribbon or white gold chain.
