This sort of Topaz location is hard to find, as it has been closed for years. Matrix blue topaz is somewhat unusual on a woldwide level (most sky blue topaz occurs as single crystals from Brazil, and parts of Africa). This piece has about a dozen topaz crystals and some blades of Wolframite, and some small gold Arsenopyrite crystals for "good measure."

It is a pleasant size. It has some minor contact where it attached to the wall and crystals didn't form. otherwise it's in good shape.
