MR79E9: These were one of the most attractive novelties at the 2004 Munich Show. This large one has perfect crystals and excellent color, with the groups of Epidote that have formed on many of the crystals of Quartz amethyst. The really amazing things are the inclusions within the crystals that include a first generation of intensely red amethyst and small crystals of really strange forms of black Hematite.

TD90C1: The crystal size and habit is bigger and better than usual for the regular Chinese Cassiterite material. But the real attraction is its transparency. Although it is not very visible due to the Quartz matrix, with the use of a strong light we can appreciate that the crystal is partially gemmy showing a clear brown rather funny phantom at its bottom left corner. Plus the contrast with the white Quartz matrix increase the beauty of the specimen.

Kėsterite and Mushistonite
 

EK88E6: In this specimen the crystals of the very rare mineral Kėsterite are on a small Mica matrix, that you can only see when you look at the back of it. The Kėsterite has very good crystal definition and the Mushistonite, that forms a thin film on the Kėsterite, give it a very neat color.

DD26E2: I have never seen Kėsterite on Beryl before. In this specimen one has a mixture of rarity (until recently crystallized Kėsterite was un-heard of) with beauty. The thin coating of Mushistonite that covers the Kėsterite adds some green to the theme, and the Mica on the base completes the whole. A beautiful rarity!
