Opal Cabochon - Height: 12 mm - Width: 9.5 mm- 0.63 g - (1)

Opal cabochons are smooth, rounded gemstones that emphasize the unique iridescence and color play of opals without the distraction of facets. This particular cabochon of approximately 12 mm height and 9.5 mm width exemplifies the common gemstone cut used for opals, designed to maximize the visibility of their vibrant flashes of color caused by diffraction of light within the silica spheres comprising the stone. Opals are hydrated silica minerals valued both for their beauty and variability, often appearing in vitreous to resinous lusters with remarkable internal color plays. Such cabochons are ideal for use in rings, earrings, or pendants, favored by lapidaries and jewelers for their ability to reveal the gem's inherent optical properties.
