These laboratory-grown opals are absolutely gorgeous! Created in a lab using the identical chemical formula as real (ground) opals, these are both affordable and less fragile. Iridescent flash adds a changing array of rainbow color. This stunning Magen David (also known as Jewish star or Star of David) is inlaid in sterling silver. The color mixes flashes of teal and Capri blue with bright turquoise. I combined it with Austrian crystal in 8mm emerald 2xAB and 4mm blue zircon 2xAB cluster drops. All components are meticulously wire-wrapped. Star and crystal dangle 1-5/8" (40mm) below the floral toggle clasp. Metaphysical properties of Opal: Promotes emotional balance and releases tension.
