I studied geology at Masaryk university (Brno, Czech Republic). In 2009 I get through the bachelor degree and continuing to masters degree. In 2013 I finished successfully masters degree.
Collecting minerals is my hobby since 1996. I like all type minerals but my favourite are quartz(mainly smoky quartz and amethyst), elbaite, galenite, calcite. I like collect in old mines, quarries, fields, caves. Most of my collection are samples from Czech Republic, but also from Austrian and Italian alps, Switzerland, Poland, Slovakia. Absolute majority self collected. If anybody can visit or want information about localities which I visited, just write me. I like change information about them, past the information about another localities.
Recently I started collecting moldavites. Moldavite is the most beautiful czech tektite. Sculptation, colour and shape is so much variable that every piece is unique. That's why I'm fascinated by them more and more

LAW-K5PQuartz (Var: Amethyst) : SiO2

Zillertal, North Tyrol, Tyrol, Austria

Dimensions: 21 cm x 5.5 cm x 5 cm

21 x 5,5 x 5cm. A double-terminated smoky Quartz with a Amethyste-Zepter on both sides. The faces show windows and mirror-gloss. The colour is very intense and the specimen is an undamaged floater.
It was found by Erika and Rudolf Planitzer in August 1976. Mr. and Mrs. Planitzer discovered one of the largest Amethyste-clefts ever, in this area. It took 5 days to bring all specimen down in the valley. The find was never published and the discovers don´t show them to many people. Now Mr. Planitzer decided to show some of the best pieces here on Mindat for the Best of Quartz/Austria Page.
