Hyalite Opal, also known as Kryptonite, Fluorescent Minerals

Discover the unique and mesmerizing beauty of Hyalite Opal, also known as Kryptonite. This exotic mineral is unlike anything else you’ve ever seen before, with a glass-like bubbly texture and even its very own fluorescent display. Formed over many years from silica and other elements such as aluminum, iron and even uranium – yes, that’s right uranium! – this special opal makes for an extraordinary inclusion to any mineral collection. But is hyalite opal dangerous? Good news: while uranium gives rare hyalite opals their green fluorescence, the stones aren’t actually dangerous. The amount and type of uranium in the stone is astronomically small, and fully contained within the crystal.
