White, Orange Opal - 2.05 ct - Antwerp Laboratory for Gemstone Testing (ALGT) - Schmuckstein

Opal is a hydrated amorphous form of silica known for its unique play-of-color and distinctive visual appeal. The specimen identified as white and orange opal weighs 2.05 carats and would be analyzed by gemological laboratories such as the Antwerp Laboratory for Gemstone Testing. White opal usually displays a milky or translucent body color with flashes of iridescent color, while orange opal carries warm hues ranging from peach to deeper tangerine tones. Opals are formed by the deposition of silica spheres in rock fractures or cavities, mainly in Australia, Ethiopia, and Mexico. What sets opal apart from other gemstones is its structural uniqueness causing a shifting spectrum of colors under light, which makes it highly prized for ornamental use. Its relative softness requires careful handling in jewelry.
