Star Necklace from Jenny Hagen By Arven. Star Necklace Silver is made of 925S silver. This piece of jewelery is a favorite from last year's collection, and is made with zircons shaped like a star. Star Necklace Silver is lovely on its own, but a complete look together with the bracelet in the same design. The jewelery is hypoallergenic. Length: 40 + 5 cm.
