WALPS-07/67 - Quartz

Zinggenstock, Grimsel area (Bern, Switzerland)

Large loose flawless gemmy highly lustrous crystal of smoky quartz. Bottom area presents some contacts. Just a tiny nick near the termination as seen in the pictures, otherwise undamaged. For size, luster, color and gemminess, quality is the best one can expect from a Swiss smoky quartz.

WALPS-07/78 - Quartz

Gletsch (Valais, Switzerland)

Cluster of doubly terminated lustrous transparent chlorite-coated light smoky quartz crystals on a piece of matrix. There are a few lustrous colorless tabular hexagonal crystal of apatite to 4 mm. across. Undamaged.

5.3x4x3 - 20 €

WALPS-07/77 - Quartz

Grimsel area (Bern, Switzerland)

Loose crystal of transparent to cloudy quartz with a very slight smoky tint. At the point where it changes from transparent to cloudy there is a void where it is possible to appreciate a partial termination partially regrown by the upper third of the crystal. Although this area may have been formed through dissolution, I believe it is instead the result of a second generation quartz regrown on a shorter previous crystal (the partial termination would be the remnants of the original crystal) to give the actual crystal. It is quite interesting as it stopped crystallization at a mid point and now we can see a "picture" of that natural process. Small black hematite crystals associated. It presents a small ding at the termination.

Val Cavrein (Graubunden, Switzerland)

Val Giuv (Graubunden, Switzerland)

Cluster of lustrous translucent to apaque smoky quartz crystals to about 5 cm. long associated to crystals and groups of chlorite-coated adularia to about 3 cm. across.
