Devilline, Dolomite, and Gypsum

Large group of arborescent flattish copper crystals from the White Pine Mine, Ontonagon County, Michigan. The specimen is very three dimensional.

Attractive gem blue variety of zoisite from Merelani Hills, Arusha Region, Tanzania. Minor showings of graphite are present around the base of the crystal.

Three well formed deep red garnets in a black schist matrix. The garnet crystals are each approximately 3.5 x 3.5cm. This specimen is from Markstay area, Awrey Township, Sudbury District, Ontario, Canada.

Undamaged grouping of tan colored calcite crystals projecting prominently from a matrix which is covered with a first generation of smaller white calcite crystals. The top crystal is twinned. An unusual locality for me in that it comes from Gralex Quarry, Mont-sur-Marchienne, Charleroi, Hainaut Province, Belgium.

Beautiful transparent blue to mauve color cubes up 2.0 cm on edge. Crystal edges are bevelled, (I believe the modified cubes are correctly described as tetra hexahedrons). Scattered pyrite is visible in the crevices around the perimeter of the specimen. The specimen is from the Jamina Mine, Corrales, Berbes – Caravia, Austurias, Spain.
