This necklace is hand crocheted from Tarnush free silver plated wire. The crystal is 30x22 mm and sparkles wonderfully!! The necklace measures 18" in length but extra links can be added to lengthen more. Each piece of my jewelry is unique ! Hand crocheted from wire jewelry is amazingly light and comfy!! And can also custom make with a different color crystal! Shipping to the USA is included in this price!
