This vintage artisan created 1970's-80's necklace features a lost-wax cast 4cmx 3cm central "star" with a 2cm resin faux amber central cabochon on an 18" silver plated chain. It is my opinion that the cast star is created in sterling silver, but as the piece is not identified with a maker's mark I cannot (within Ruby Lane's guidelines) state it as being silver. However, it is not unusual for sterling artisan created pieces to be unmarked (Cypress Studio offers a FULL refund policy, including shipping BOTH WAYS, if you are not fully satisfied with your purchase). This being said, the piece displays impeccable aesthetics and has a great mid-century vibe. A great piece!
