Hyalite Opal, Gallatin co., near Bozeman, MT

Description

This piece is 35 grams. A rich coverage of Hyalite on Basalt, with two area's as "highlight. A good piece for the localities. Great esthetics and Fluorescence on this specimen.
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....
However, as the photo's show, this is great Hyalite, perched in the center of it's host rock, which is Basalt. As shown, Hyalite is very Fluorescent under Shortwave UV, and displays a vivid lime green glow.
Please be advised, I ship with Parcel Select.
