Hyalite is a special, colorless variety of Opal that grows in volcanic formations. Although these Mexican stones do not show typical opalescence, they have their own unique trait - fluorescence! Hyalite contains trace amounts of uranium within its silica structure, causing it to have a bright fluorescent glow. These gemmy Hyalite Opal specimens from Mexico have a vivid green glow when they're exposed to UV rays and remain translucent crystals in incandescent light. These specimens will have some areas of grape-like botryoidal growth and all will range in translucence with clear to milky coloring. These self-standing stones make perfect display pieces, featuring Hyalite atop of a sliced and polished host stone. Their bases may display deep brown, grey, and soft periwinkle coloring. Each specimen weighs between 20 grams and 25 grams.
