Yaogangxian Mine, Yizhang County
3.5x3 CM (small miniature)
Very bright, metalic and with fine luster, this bournonite miniature shows excellent form with a pleasing contast to the matrix. Much better than usual condition for this delicate, brittle mineral, however there is some chipping and contacting like all of these have. The main crystal shows a fantastic cogswheel form. Since well crystalized Bournonite is very uncommon, the better Chinese examples are already becoming classics. For now, this is a bargain!
A pre-1930's piece from the classic location of Bad Ems, best known for fine pyromorphites. This is a sharp, glassy cerussite with only minor edge chipping. It is rare to see minerals of this quality available from these old European locations.
Barite on Calcite
Stoneham, Weld County
4.2x4.1 CM (miniature)
Nice light blue Barite, standing on a contrasting yellow crystaline calcite. The main crystal is 2.7 CM and sharp with no damage. There are some very small crystals scattered on the matrix that do show damage but they are not distracting. An attractive piece from this classic American locality, at an attractive price.
