This unique design includes a high quality Mexican fire opal, rainbow moonstone bead, pearl crescent moon and 14K gold fill wire. It sits at a height of 2.25 inches. Please choose between a 16 or 18 inch 14K gold fill chain.Cleaning instructions: You may clean the piece with a mild soap and water and then dry it thoroughly with a lint free cloth. I do not recommend immersing it in water often (such as bathing or swimming with it) or sleeping with it on. You can also use a polishing cloth to help keep your jewelry looking fresh and new.
