Do not purchase anything from here! This company is based in China, they have no phone number and the Customer service is terrible. I ordered a necklace and requested to upgrade the stone. Betty confirmed the specs and cost with me, I paid the upgrade cost, which was double the costs of the necklace. I got the necklace right before Christmas and it had the standard quartz stone, NOT the opal I paid for. They refuse to refund me the upgrade cost or send me the opal stone I paid for. Buyer be aware! This site is a scam
