Description

For decades the only minerals which sometimes came on the market from entire Ireland were some unimportant Quartz and Calcite samples. Ireland seems to own really very few relevant mineral specimen. Until the discovery in Larkins Quarry. A few years ago a first important discovery was done - it was really a sensation. For decades; for centuries there was not even one important discovery in Ireland and then these amazing fluorites were found - intense, dark purple crystals came out; cubes with additional modifications of rhomb and even wih lustrous faces. And now look at this fantastic crsytal:

It shows a dark violet body, a light sky blue area and in the center a octahedral phantom! This octahedron was also dark purple. If you look carefully - ether is a thin colorless light cross exactly in the middle - I think the octahedron must show thin colorless modification along the edges. This is completely different to the material from 2016 and it is fantastic!
