DZ1903 - Tourmaline var. Elbaite
Mt. Apatite, Auburn, Maine
thumbnail - 3.1 x 1.0 x 0.4 cm

An unusual flattened gem tourmaline crystal. Oddly, it only has five sides as if one half of the crystal is missing, yet the entire piece has natural crystal growth.

DZ1909 - Bournonite
Viboras Mine, Potosi Dept., Bolivia
miniature - 4.8 x 3.1 x 2.9 cm
$ 500.00

Classic cogwheel twinning. The bottom surface looks a little rough, but on close inspection it is terminated all the way through. The rough texture is likely due to growth inhibition from the pyrite matrix.

DZ1912 - Arsenopyrite on Quartz with Muscovite
Panasqueira Mine, Barroca Grande, Beira Baxia, Portugal
small cabinet - 8.6 x 5.5 x 5.4 cm
$ 750.00

After all these years of collecting, Panasqueira is still one of my favorite localities. This specimen has a single euhedral quartz crystal with an unusual and appealing luster on the pyramidal faces. The back half of the quartz crystal is draped in small muscovite books. Several large arsenpyrite crystals eminate from within the quartz to form a crown on the top.
