This bracelet is made of segments of 6mm AB crystals with a white opal crystal in the center. AB stands for aurora borealis which is a finish that makes the crystal reflect the light. All crystals are Swarovski. The total length with the clasp connected is 8 1/4". The clasp is a silver toned button clasp. Button clasps are reliable and pretty easy to put on. This bracelet really sparkles. I get a lot of compliments on the one I made for myself. I also include a free handmade jewelry bag with every jewelry purchase. I don't charge for shipping within the 48 continental United States. If you live outside of that area, please message me and I can give you an estimate on shipping costs. Thanks for shopping!
