Description

Hyalite isa typical associate on many specimens from the Erongo mountains, and is often removed. However, it is an intensively yellow fluorescing mineral that displays very nicely under UV light. You will be surprised how that will turn out then. On this specimen it is covering a foitite crystal. The foitite crystal is a bit loosely attached to the hyalite which is quite common at this association and has not been fixed for keeping the specimen authentic.
