This is some of the most fluorescent hyalite opal that I have ever seen. Even in natural light it is green, and when a UV light is turned on it, WOW! It glows! It is perched on a nice terminated smokey quartz and sits in a thumbnail box. Notice the measurements in mm and not cm.
Size: 30x25x25 mm
Location: Natural Light, Erongo Massif, Namibia
