This Hyalite Opal is exceptionally large with the vug entirely coated with a massive and thick layer of transparent, colorless botryoidal Hyalite Opal. The Hyalite exhibits intense green fluorescence when exposed to ultraviolet light. Additionally, the adjoining brown matrix has been polished to highlight and accent the Hyalite. A stunning piece and a great addition to any collection, especially for UV fans! In excellent condition.
