A novelty at Tucson 2014. Transparent botryoidal growth on matrix. This kind of Opal (variety hyalite), in addition to the fact that it is gemmy and quite aesthetic, standing up on its matrix, has the extraordinary property of fluorescing in daylight! In fact, it fluoresces in almost all types of light, neon light, LED light, daylight and, of course, UV light. The only light with which it doesnt react is incandescent. As they are so new the locality is still very vague, sorry for that, but we are sure that time will clarify the locality as well as the reason why they fluoresce so strongly.
