Our exclusive ELECTRIC CASTLE COLLECTION features museum piece Opalized Shells from the ancient inland sea in Australia! Wearing a piece of Opal is rare but having the privilege to enjoy wearing a fossil that is over 100 million years old which has been Opalized is even rarer! These White Opal Jewelry items are museum pieces and will be handed down from generation to generation. Every unique piece is hand polished and handcrafted by our skilled Opal Jeweler. Only available here on Australian Opal Direct, these rare, one of a kind museum pieces will not last. Hurry, before this collection is gone!
