No reserve price - 2 pcs White, Multicolour Opal - 10.24 ct - Antwerp Laboratory for Gemstone Testing (ALGT) - NATURAL OPAL

Opals are celebrated for their mesmerizing play of color and unique internal patterns, making them one of the most distinctive and captivating gemstones. White and multicolor opals feature a lighter body tone ranging from milky white to translucent, often displaying vibrant flashes of color such as reds, blues, greens, and purples within their structure. This duo, totaling over 10 carats, offers a varied palette and brilliance that appeals to opal enthusiasts and collectors alike. Each opal stone is a hydrated amorphous form of silica, and their characteristic play-of-color results from microscopic silica spheres diffracting light. Natural opals like these, authenticated by the Antwerp Laboratory for Gemstone Testing (ALGT), are prized for their unenhanced and genuine qualities, distinguishing them from synthetic or treated counterparts. Opals' unique, almost mesmerizing color patterns make them popular for artistic and fine jewelry applications, where their singular beauty can be fully appreciated.
