Multicolour Opal - 22.81 ct - International Gemological Institute (IGI)

Opal is a hydrated amorphous form of silica, renowned for its unique play-of-color—an optical phenomenon that displays shifting spectral hues when viewed from different angles. Multicolour opals can show a vibrant spectrum, ranging from reds and oranges to blues and greens, making each specimen unique and highly prized. With a weight of 22.81 carats, this opal is quite large, suitable for bold jewelry designs or collectors seeking dazzling display pieces. Opals require careful handling due to their water content and relative softness, so they are often set in protective mountings. An International Gemological Institute (IGI) report adds further reliability about its quality and natural origin.
