About us:

For 30 years I taught mineralogy in several Brazilian universities, always seeking to give a practical vision.
I passed from laboratories classes to field classes leading the students to the states of Minas Gerais, Bahia and Espirito Santo, showing them the largest Brazilian minerals resources. I created a circle of friendship among the miners, prospectors and small regional merchants and I formed my private collection, nowadays my collection consist of some thousands pieces. Upon a visit several websites I realize that many interesting samples are not offered to the public.
I learned from my studies that the old collectors can be interested on these minerals and the beginners can find materials at low cost with a great esthetic value. Thinking about that I organized this web-site to offer you pieces that are not available in any other web-site.
