Turquoise Shark Tooth Necklaces. We know you will want to swim in the ocean with your shark tooth necklace so we used waterproof vermeil gold for this piece, and we always use authentic stones, so our turquoise is 100% real Arizona turquoise.The shark teeth we use are found on the shores of Florida and are all a bit different in size and shape. You will receive one shark tooth necklace. Gold with turquoise and white tip. Some photos show other pieces as layering options and styling inspiration.
