Cassiterite on Quartz
stock #18AX-12-417
Amo Mine, Ximeng
Yunnan, China
3.8 x3.4 x 2.2 CM (miniature)
price: $440
Late Summer 2018

Cassiterites in gemmy crystals with brilliant luster and sharp form. The Amo mine in Ximeng county (Yunnan, China) produced a few spectacular Cassiterites. They were immediately prized and have almost disappeared. Unlike from any other location, these had a unique, recognizable style that could be very esthetic. This fine example is sharp, well formed, nicely perched on a cluster of quartz crystals that have some green inclusions as a bonus. In great condition there is contacting only on the back side not in view. In some photos what may look like damage is internal reflections inside the Cassiterites. Much better in person.
Cassiterite & Stibnite (Bismuthinite?) on Quartz (rare association)
stock #ALEC-15-279
Amo Mine, Ximeng
Yunnan, China
5.2 x 3.8 x 2.1 CM (cabinet)
price: $300
Winter 2016-17

A bizzare association, well formed slightly translucent Cassiterites sitting on Quartz with a crude 5 CM Stibnite crystal along one edge. The question was recently asked if this is Stibnite or Bismuthinite, and we have not yet made an analysis. The Cassiterites have good luster and form, very three dimensional. Ex Shields Flynn collection, via Bert Ottens, I have never seen another of these. There is a matrix repair that is not visible.
