These 12mm lapis beads are the most desirable kind - dark blue with a liberal scattering of fool's gold (iron pyrite). There are 14K hollow fluted gold and tiny gold spacers. Strung on chain. 16 1/2" long, closes with a hook and clasp. Marked 14K on the clasp. You couldn't be happier with this lapis necklace. Excellent vintage condition.
