Hyalite opal, nice Thumbnail, Gallatin co., MT, (Fluorescent!)

Description

Like a little bolt of Lightning, that is how this wonderful thumbnail sized specimen of Hyalite looks under Short wave UV! for it's size range, his specimen is perfect. Enough Hyalite to impress, but also enough matrix to provide a captivating contrast. the specimen is 7 grams, but commands the presence of a much larger piece.
Hyalite Opal, Fluorescent, from Montana! Even though crusts of Hyalite Opal have been known from Montana for decades, good quality specimens are rarely seen on the market from the state. A new claim in Gallatin Co., MT, has recently produced specimens of a quality rare to the state, more reminiscent of classic Mexican and Hungarian Hyalite Opal. I will post a number of these pieces in the upcoming period
The here presented example is great for the species, as well as Montana as a locality, but also for collectors of Fluorescent minerals. Apologies for the poor photo's, as Hyalite is difficult to photograph, short of a professional photography set up, leave alone out of hand with a Phone camera....
