Hans Hansen Denmark Rock Crystal Necklace

Very rare & extraordinary sterling silver pendant with a large natural rock crystal sphere designed and produced by Bent & Helga Exner for Hans Hansen in the 1960s.

WIth it's original signed Hans Hansen long sterling chain. The pendant hallmarked "Hans Hansen" in script, "925S, Denmark." The chain marked HaH for Hans Hansen.
