Description

A fantastic piece from the "Knappenloch" - my new find from the Weisseck Mountain 2022: the crystals show a beautiful intense violet color on the outside and a deep blue to cyan color on the inside. This color build-up causes the fluorite to change color as the piece is moved. The fluorite measures up to 4.1 cm at the edges. The crystal surfaces show a fine square texture with a silky luster due to water etching. Two distinctive features of this new find can be observed in the crystal domain: the dark purple spots, most likely from radioactive radiation, and isolated bright intergrown “Hahnenkamm” barites in the surface of the fluorite. The piece is etched or crystallized all around with beautiful structures - no new fresh damage. The piece has an old contact at the front on the crystallized side of the fluorite. The contact is healed by water etching with fine structures. First, and third photo with medium LED backlight.
