SOLD Calcite with Siderite

Colorado, United States
6.2 x 4.8 x 4.2 CM (cabinet)
price: $0

Well-defined Calcite rhomb crystals to 2.8CM across, on a contrasting Siderite matrix. The Siderite is botryoidal with a few isolated balls. In excellent condition as seen, the Calcite is fluorescent a good red color. Ex Frank Knaus and Dave Bunk, this is well above the usual quality for these Shale deposits, which we understand are either exhausted or off limits to collecting. A nice Colorado Calcite.

A sharp and quite lustrous Brookite crystal 1.1 CM across, with textbook perfect form, is perched on a milky Quartz crystal. The Brookite has an unusual blue iridescence on some faces, though it mostly looks black. A classic locality that is well-known for good Brookites that are very different from those well-known from Pakistan. An older specimen collected before 1969. This could be trimmed to be a thumbnail if desired but it is quite nice as is. The wider faces have complex geometric stepped structures well-presented. There is no damage at all.

Late Summer 2021

A modern classic, an early Xuebaoding type Beryl from Pingwu vintage 2004 season. The Beryl is very glassy the broad faces of the tabular crystal have complex geometric facets from both etching and multiple recrystallizations. The outer narrow faces are sharp and glass-like. Just one narrow edge has some damage not visible from most logical viewing angles but overall the condition is outstanding. The most prominent Albite crystal is a blocky type with pearly luster making a nice contrast. This form of tabular Aquamarine Beryl is rare worldwide but this high elevation locale has almost all of its Beryl in this form.
