This lovely necklace is a bit hard to date but from the clasp I would say 1920s/30s. It’s fashioned from banded or Scottish agate and 10k yellow gold. The beads are faceted which is unusual and they’re oval shaped. The colors are mostly gold, brown and white. The necklace measures about 15 7/8 inches in length and 1/4 inch wide and the condition is very good.
