Description

This mine is known as one of the world's best localities for apatite and the best for Europe! This is an old piece with the best quality of apatite with superb form and luster and the classic green phantoms on a quartz point of equal quality!The quartz crystal is very special and this could be a quartz specimen, since this is a scepter like formation of a gem clear lustrous crystal growing on top of a second previous generation point that was covered by mica!The result is a combination of scepter and phantom effects, but is hard to categorize!It even has an "s" face on the termination! On the back and near the bottom the piece is contacted with no damage!The group of apatite is covered with mica on the back and are almost gem in person with no damage!Please note that fiding this quality for each species from the locality is difficult, but to find them all in one aesthetic assemble is nearly impossible!
