You have found the PERFECT unicorn necklace!! Hours upon hours were spent carving tiny stars, moons, and lightning bolts into the wax model of this unicorn. Time well spent, I think. We can now cast a silver or gold version for you to adorn yourself with! Dimensions: Tattooed Unicorn measures 1 and 3/4's of an inch tall from the horn to hoof. The unicorn is 1 and 1/4 inches wide. The Necklace is adjustable measuring 17 inches at its shortest and 21 inches at its longest. Materials: Silver Tone: Solid white brass charm and chain Gold Tone: Solid yellow brass charm and chain Sterling Silver: All parts are sterling silver Our base metals (Silver Tone and Gold Tone) are both 100% brass. White brass is a metallic alloy that is made of copper and zinc. All my jewelry is hand made by me, Karen Yost, in my NYC studio at the time of purchase.
