Classic Rocks and Spheres

Spheres from Glacial Erratics

Interest in these Scandinavian stones, known as "glacial erratics"started on a vacation to the North Sea. While walking on the beach I noticed a pile of pebbles, Gniess,Quarzite and Sandstones....I recalled my teacher at the Den Haag Lapidary Club in Holland mentioning these stones during the lessons.

My next trip was to the Baltic Sea where these stones are abundant along the coast. in this area the stones are mostly from Sweden,Finland and the surrounding islands. The following summer went to Fehrman Island and finally along the north-west coast of Denmark. In this area the stones are mostly from Norway .

After having collected a substantial amount I started cutting and polishing the stones into sections so as to be able to identify them . Over 300 types have been classified to date but many more which lie on the beaches  have no name . The beautiful Flame Pegmatite was only named in the early 1990's.

Consequently came upon the idea to cut spheres from these rocks and after some research developed machines to do this.I identify the stones using pictures and texts written by qualified petrologists who are specialized in this field,mostly from universities and museums in northern Germany and the Netherlands.

The process of cutting perfect spheres is very labour intensive and the machines are used only to obtain a perfect spherical shape, the initial cutting of the rough rock into a cube and octagon is done by a diamond saw and the subsequent grinding to a round shape is done by hand on a diamond grinding wheel.

Am now emloyed full time in this activity, take a look at the Web Store and More Spheres on this site if you are interested in adding some spheres on to your collection : you can E-Mail me at : marco.classicrocks@gmail.com
