Hyalite Opal, on Basalt matrix, Gallatin co, MT, Fluorescent, top quality, rare!

Description

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 "crown" of 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.
The Specimen is 4x3x2 Inches, the weight is 13 OZ(nearly one LB), or 360 grams.
Please be advised, I ship with Priority shipping.
