When I started making jewellery I found out that I needed the gemstones which completed my designs. I didn't want to depend on the gemstones in the market. Therefore I learned faceting and I bought my Facetron. You can see the machine and the diamond tools here. 

Also I learned stone cutting and faceting in the workshop of Hans G. Gordner and gem carving in Hans Ulrich Pauly’s workshop in Idar-Oberstein.

When I was in Canada I have been cutting my stones in Montreal Gem&Mineral Club.
