Cassiterite - large and gemmy crystals, classic
stock #17.1-367
Viloco Mine (Araca Mine), Loayza Province
La Paz, Bolivia
5.8 x 4.7 x 3.2 CM (cabinet)
price: $1750
Spring 23

A super esthetic old Bolivian Cassiterite. Mostly all Cassiterite crystals with just minimal matrix and a few small Quartz crystals, in exceptional condition. The luster is glass-like and the crystals are fully translucent to transparent. The photos here are not backlit but with rear lighting the crystals glow a bright yellow-green to orange. The largest crystal is 4.2 CM across, which is huge for the locale, very few came close to that size and almost never with this fine form and luster. In excellent condition as seen, there are minor small edge rubs to mention but no damage. This from the Les Hitchings collection which he obtained in 1985, the era of the top finds at this amazing locality. Cassiterite of this quality has not been seen since then. This piece does look a lot like a fine Chinese Amo Mine Cassiterite in form but the larger size of the crystals and the internal color are distinctly different.

Copper pseudomorph after Aragonite
stock #20.1-302-(LW1064)
Corocoro, Pacajes Province
La Paz, Bolivia
1.3 x 1.2 x .5 CM (thumbnail)
price: $190
new year 2021

A perfect small thumbnail of native Copper that has faithfully replaced a hexagonal Aragonite crystal. The Aragonite form is textbook perfect and the patina is a choice red copper hue. No damage, complete all around this is both sharper and with better color than usually seen. These pseudomorphs were found more than 30 years ago and not since. Ex Larry White collection.
