Super form showing epitaxial arrangements and a textbook structure in this esthetic Kazak Fluorite. Impressive and quite unlike any other sort of Fluorite from anywhere in the world. The main crystal is 4.8 CM across well perched at the top of a mixes mineral matrix. In excellent condition overall as seen though some cleaves are present with some crystal regrowth over those spots. Way better in person, this is a choice example from a find more than 2 decades ago and no longer seen on the market.
A fine, sharp, well crystallized Butte Covellite collected in Butte before 1966 by Paul Heissfeld. Comes with Heissfeld and Larry Conklin labels. Larry notes: An excellent mass of large crystals and no matrix.
Classic form and habit, very good blue and gold iridescence amid the dark crystals. Covellite crystals of any size are rare and best known from just two localities, both long closed.
Unusual habit with brilliant red-orange color and many gemmy crystals forming a very attractive Serandite from the great Mt St Hillaire. The largest crystal is 2.5 CM across and is a blocky style, but the smaller crystals show many different habits and terminations. Some of these are Bipyramids or have complex parallel prisms and multiple stepped terminations. The luster is excellent, the condition is overall quite fine there is a break on backside where removed and a few very small wilbers noted on minor crystals only seen with 10X magnification. Classic locale and specie, attractive and unusual.
