Hyalite Opal

Shop our collection of natural Hyalite Opal, a distinctive variety of Opal known for its glassy, transparent to translucent appearance and remarkable fluorescence. Explore hand-selected rough pieces, natural formations and one-of-a-kind mineral specimens displaying clear, colorless, white, cream and softly tinted areas. Many Hyalite Opal specimens can produce an intense green fluorescence under ultraviolet light, creating a dramatic contrast between their appearance in normal lighting and under UV. Each specimen is selected for its formation, clarity, fluorescence and individual character. Exact Piece items are individually photographed so you can see the actual specimen you're choosing (unless marked otherwise). Looking for a specific size, formation or UV response?
