A semi-precious stone with usually a spectacular color play in it, Opal is thought to be one of the most popular gemstones to both jewelry designers and makers, and gem and jewelry enthusiasts. This stone can appear in light to dark hues, with the dark-toned ones considered to be more valuable and priced as they display the most [color] vibrance and brilliance--with black being the most precious and priced. Those with unique and rare patterns, are also considered to be more expensive than other varieties with simple marks. Although Opal stones are relatively soft, with a hardness score of 5.5 to 6 in the Mohs scale, they can be made into cabochons, beads and brooches, especially when cut and shaped carefully.
Our collection of Opal cabochons range from light to dark-hued cabochons, with plain or patterned appearance. Most of them are highly polished, but some are also lightly polished to preserve the beautiful the slight druzy texture of the stone. They also come in different shapes, with the fancy ones including a pentagon and a parallelogram. Among our rare Opal cabochon pieces are a rare green Opal with pinpoints that look like green glitters inside the stone, and a multicolored Opal with a beautiful play of red, blue and black color patches.
Along with pink tourmaline, Opal is also a birthstone for the October babies.
