International minerals #30

This crystal is on very high quality - it is much more translucent as material on average and shows almost glassy character. The colors are typical, but more intense as usually. All faces are lustrous, there are no repairs neither any significant damage.

Light blue, end-pointed crystals with glossy faces set on muscovite matrix. Good contrast and in good condition overall. Hard to photograph, more 3-dimensional and better in person

This blows records - a sharp terminated, well shaped crystal: almost 6 cm thick and over 10 cm in diamter, without damages and contacts! The weight is over 1kg (to be exactly: 1072 gramms). It shows the classic pigeon-blood red color. Of course it is not in gem-grade, but still unbelieveable to hold a Ruby in this size and quality in your owns hands.

A sharp terminated Ettringite with lustrous faces and even end-pointed. The small black octahedral crystals on it are Hausmannite, the elongated crystals are Gaudefroyite - that is a quite rare and spectacular combination!
