{"product_id":"oval-genuine-white-opal-cabochon-5x3-10x8mm","title":"Oval Genuine Opal Cabochon","description":"\u003cp\u003eOpal is the world's most popular phenomenal gemstone, with many cultures believing that opals had supernatural origins and power. Inside each opal, sub-microscopic spheres are stacked in a grid-like pattern — similar to a layer of ping pong balls. When light strikes these spheres, the waves bend and break into spectral colors, producing a flash of rainbow colors known as \u003cem\u003eplay-of-color\u003c\/em\u003e. These oval cabochons feature a translucent white background with medium to strong play-of-color, making them a striking choice for fine jewelry settings.\u003c\/p\u003e\u003cp\u003eWhite opal displays its characteristic play-of-color against a white to semi-translucent body. Color flashes range across blue, green, and red. These stones are offered in a range of standard oval cabochon sizes, suitable for a variety of bezel, prong, and collet settings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Opal is an exceptionally soft and moisture-sensitive stone.
