I made this blue opal necklace with Indonesian blue opal petrified wood and solid silver 999 fine and 925 sterling. This stone came to prominence in 2018 or so and is prized for it's brilliant blue color. It's one of the very best petrified woods ever to be found. This type is opalized pet wood and often contains some micro copper. It's popularity led to the deposits that were found selling quickly and it's now a rare and valuable stone. I chose a scalloped bezel to hold this opal. The pictured 20 inch chain is solid sterling silver. Including the bail this pendant measures 1.46 x .69. The blue in this type of stone is usually a very small section of the overall rough with brown composing most of it. A stone this size without the brown is rare. In the global market we encourage you to shop local by supporting artists and small businesses who cut stones safely and ethically within the U.S.A. All of our stones and fordite are made by us, within our home, in Wisconsin. Our stones are mirror polished and so there will be reflections in the pictures. We take pictures in direct bright light that simulates what your stone will look like in direct sunlight. Stones look very different in low or artificial light. If it's dark when you receive them you can use the flashlight feature on your smart phone to see what they will look like in daylight. If you are new to semi precious stones please understand that these stones are natural and were found or dug from the earth. These are not faceted altered or manmade stones you see in stores. Natural stones (especially agates) may have features that would be considered flaws in a faceted stone or manufactured stone. Natural stones can have internal fractures, natural holes or geode areas. If there are features we as professional lapidary artists feel may detract from a stone we do our best to describe them in the listing description and show them in the pictures.We charge based on size and quality of the stone as well as market factors. We don’t dabble in the art of stone cutting. Brian is a full time lapidary artist so if you buy from us you are buying a high quality stone made by an experienced professional artist. We are a legitimate small business licensed as an LLC in Wisconsin. Our business mission is to create happiness through our art. Shipping: The free shipping for our shop is USPS Ground Advantage.
