The Hyalite Opal is the clear, globular layer on top of the white Milk Opal in this specimen. The Hyalite fluoresces a brilliant green under a short-wave UV light. In this specimen, the Hyalite is transparent.
HYALITE is a colorless variety of Opal. Hyalite has a different internal structure than that found in Precious Opal. Thus, Hyalite does not exhibit the opalescence that is found in Precious Opal. However, Hyalite does fluoresce green under a short-wave ultraviolet light. Hyalite occurs as globular and botryoidal masses and irregular crusts in volcanic and pegmatite environments. Hardness is 5.5 – 6 on the Mohs scale.

The Dioptase center actually looks greener in person! For some reason the picture captures it as blue but it is a sparkly shiny green color with Chrysocolla around it. The Chrysocolla you is is the actual color.
