Bear Creek Canyon, Colorado Springs area
4.3 x 3.2 x 3.1 CM (miniature)
A nice, colorful Amazonite crystal collected by the late Dr. Warren Johansson in 1945 just prior to his induction in the US Army. He had treated himself to a solo mineral collecting tour of the US Western regions while awaiting being shipped out overseas. He wrote a nice memoir about that adventure some 65 years later. The color is a little richer than most seen from this locality, the condition is quite good, there are several clean contacts but there is no damage or bruising. A classic US specie from Colorado, with some extra provenance.
A very well*-formed example of Goethite crystals on a Smokey Quartz prism. The Quartz is unusual in that it is doubly terminated and in very good condition. The "Ongeite" is in blocky curved rhombic crystals and stacked groups. In much better condition and distinct form that we usually see, this is from an older Northeast collection obtained from Lazard Cahn (no label however) in the early half of the 20th century. A distinctive and classic American specimen these are unlike anything else from any other locality. A few areas of the Quartz have red staining that is also typical of this region.
Mauldin Mountain, Montgomery County
5.1 x 3.3 2.3 CM (small cabinet/ large miniature)
An isolated, distinct hemisphere of Wavellite on contrasting matrix. A USA classic from Mauldin Mountain, the sphere is composed of tightly packed crystals that have a nice sheen in person. In excellent condition, the color is a little deeper than the photos show. An older specimen, these Wavellites are considered by many as the best from the USA and yet still quite affordable for a nice piece.
A small, well-composed specimen of Amethyst perched on a contrasting matrix with a druse of greenish Epidote. From the prolific finds at Piedra Parada, the Amethyst is distinctly sceptered and in perfect condition. These Amethyst when they are perfect like this are one of the best current values in minerals. We hope the locality can continue to produce for a long while.
Sao Jose do Safira
4.1 x 3.1 x 1.5 CM (miniature)
Late Summer 2021
A single, blocky but somewhat tabular Colombite crystal. Distinct although rather crude, the crystal is fully terminated and moderately lustrous. An older piece from Sao Jose do Safira (Brazil) this is a very good miniature of this commercially important pegmatite mineral that is not often considered "pretty".
Some masses of native copper mixed with gem clear Calcite crystals, most of which are richly included. A complex specimen on an amygdaloidal basalt matrix having many cavities filled with micro crystals. These vugs hold many Epidote crystal clusters most being on contrasting salmon colored crystals of Microcline. Good looking by naked eye but really amazing with magnification, this has a good mixture of species and is classic upper Michigan material. Unfortunately we have no mine attribution but this looks like a perfect match to the famed Quincy Mine.
Adamite crystals in pale green balls scattered on a contrasting red Gossan matrix. In fine condition as seen, the balls are in clusters and a few are fully isolated. Good sparkling luster in the spheres and with nicely fluorescent as well. Adamites from Ojuela are incredibly varied in color and habit, some forms do not exist in any other locality world wide. Modern classics this is an affordable yet very pretty specie and specimen.
A transparent and nearly pure crystallized Pollucite that has been heavily etched. Aside from some tiny inclusions this is all Pollucite with total transparency, and curved crystal faces. Pollucite is one of the few sources of Cesium and sometimes also includes substantial amounts of Rubidium, it is an uncommon gemstone as well. The specimen is broken on the base or underside where it was attached but the visible surfaces are in fine condition and show the characteristic Pollucite structure and luster perfectly. This is just under 36 grams of gem crystal that is very lustrous in person.
