Gold in Quartz
Henderson Mine, Chibougamou
3.8 x 3.7 x 2 CM (small miniature)
Gold in crystals, sheets and massive zones densely filling a veined Quartz matrix. From the Henderson mine in Chibougamou, this is an especially rich specimen from the locale that is famed for the worlds best Cubanites. Very few specimens of Gold have been preserved from this locality, Ex Glenn Petrie, and Les Hitchings collections. The Gold is visible on every surface of the matrix, and under magnification the richness and complex delicate structures are very elegant. Total weight of 34 grams I would guess the bulk of that weight is Gold.
Very well formed, lustrous and complete on all sides, a fine cluster of bright metallic crystals. From the famed Tristate district, relatively few specimens were attributed to individual mines but this piece is noted as from the Mid-Continent mine. In excellent undamaged condition with a "gunmetal" patina a fine specimen from a classic and long closed area.
Jeffrey Mine, Asbestos
3.1 x 2.1 x 1.2 CM (thumbnail)
Jeffrey Mine thumbnail with a main 2.5 CM crystal standing above broken but recrystallized smaller Vesuvianites. The main crystal is in good condition as seen, the color is good and displays well. Attractive from all angles, a nice example of the habit from this prolific but closed locality.
Vintage specimen with old EB Underhill label. Underhill donated his collection posthumously to Amherst College in 1888, so this piece and his handwritten label is older than that. Not many of these labels survive today and the Sphene specimen is also a very rare example from a classic locale. I have never seen another quite like this, the luster is very bright on the slender dark gem clear crystals in the protected vug. Microscope reveals tiny Clinochlore and what may be colorless Fluorites, not known from this locale. A nice slice of mineral history.
A weird but super attractive Fluorite from the Erongo where odd Fluorites seem to be more common than other places. The photos do not convey the piece well, but it is composed of many "melted look" globlike transparent crystals in clusters and stacks on Schorl crystals. The colors range from colorless to vivid green and all looks like it has melted together. A few transparent green needlelike Tourmalines are scattered on the display side for added oddness. Far better in person.
Calcite -complex twinned
Gralex Quarry, Mont-sur-Marchienne, Charleroi
3.4 x 3.4 x 2.3 CM (small miniature)
A choice small specimen from this noted locale. The Calcite is undamaged, mostly transparent and shows complex twinning. This locale produced many habits and some top pieces over the years, but it is now finished. This is a small, cute, affordable piece from this important locality with a nice arrangement.
Copper- twinned crystals
Itauz Mine, Zhilandy group
5.5 x .9 x .4 CM (small cabinet/ large miniature)
Complex twinned crystals in a branching display with fine patina. No damage, a choice example of the great spinel twin habits that have been found in Kazakstan. Looks fine on all sides, a very good value.
Realgar with Calcite- gemmy crystals
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
7.2 x 5.2 x 4.8 CM (cabinet)
A fat, intense red main crystal dominates this Realgar specimen. The Realgar is the less common blocky habit and has top vivid color. Glassy luster, transparent to translucent and a strong display piece. Mined over a decade ago this has been in dark storage ever since so it is pristine and fresh looking. No more is coming out, this is a very choice example. There is damage on the backside where it was removed that is not seen, the front in is fine condition and showy.
