This beautiful boulder opal pendant has the flashes of blue, pink, yellow, and green. The stone is set in a solid 22K gold bezel with 14K solid gold back sheet. The chain is made of 14K solid yellow gold and 16"(40cm) long. 【Boulder Opal】 Because each stone's shape and colors are so unique that large jewelry store chain cannot sell boulder opal. Boulder opal is found only in the state of Queensland, Australia. It is one of the most valuable opals due to its beauty and rarity. I use No doublet/triplet. 【Pendant】 Boulder Opal (from Australia) Pendant: H5.5mm x W15mm 22K gold, 14K gold 【Chain】 14K Solid Yellow Gold Length: 16" (40cm) Made in my home studio near New York City. 【Wrapping】 All of my jewelry come in a beautiful gift packaging.
