Welcome to Diederik Visser Minerals & Petrological Services.
Diederik Visser Minerals is a mailorder business located in the city of Deventer in The Netherlands. Its major activity is the sale of relatively rare minerals in the US$ 1 to US$ 200 range for the beginner and the advanced systematic mineral collector, museums and research institutions. More common minerals and rocks are also available.

I also like to bring you books & literature on Mineralogy, Old Mining Stocks and
other mining collectibles.

If you are interested in the Petrological Services please inform via email.

I hope you will enjoy the pages.
