The Cairngorms in early June this year. Still quite a lot of the winter’s snow about. On the plus side there were no midges. The mountain in the distance is called ’Cairngorm’, after which the range of mountains is named. It’s summit is 1244m, over 4,000 ft above sea level. Everywhere is granite. (Author: Mike Wood)

The combination between a cube of fluorite and a scalenohedral crystal of calcite is very nice. This sample comes from the "Emilio" mine near to the village of Loroñe, Caravia-Berbes region.
The crystal of Calcite have 8 cm long.

The copper shist district Mansfeld-Eisleben-Sangerhausen (Saxony-Anhalt) is - among other things - famous for its gypsum specimens. Most collectors know the colorless and grey crystals from Eisleben. From Sangerhausen (Thomas Müntzer shaft) brown elongated crystals are frequent. A certain variety are "Weißkopfgipse" (white-headed gypsum) from that locality - black crystals with colorless tops. There are big samples with crystals standing closely packed: a feast for the eyes! (Author: Andreas Gerstenberg)

The crystals here of Stibnite are very small averaging 1/8" to 3/8" (3mm to 9mm) in length. The specimen is from , the aptly named, Stibnite Creek SW of the town of Tok, Alaska. I picked tis one up in 1996. It is 2 3/4" x 1 1/2" x 1 1/2" (11.4cm x 3.8cm x 3.8cm) (Author: Jim Prentiss)

The cubic crystals present geometrical zones of color, some of which have inner oriented inclusions of sulfides, probably Pyrite. A border of white crystals of Calcite partially skirts the specimen.

The East side of Ben a’ Bhuird is fringed with precipitous cliffs and corries, formed during the last ice-age, resulting in lots of exposed granite rock. There are not many pegmatites to see around here though, and what you find in exposures tend to be thin and stringy. (Author: Mike Wood)
