I collect and sell minerals from the Jeffrey Mine, Asbestos, Canada and from Quebec region, Canada, and heliodors from Volodarsk-Volinskiy, Ukraine. My collection has other worldwide display quality specimens, but focuses on the Jeffrey Mine and other Asbestos mine in Quebec, but I am well known also for my top-quality Ukrainian heliodors in my collection and in other top collections worldwide (my wife is from there).
I am the author of the 2003 article on the Jeffrey Mine in the Mineralogical Record and the author of the Quebec section in the recent garnet issue of the English Extra-Lapis (Litographie). In these articles some of my specimens have been photographed, but they also appeared in La Rivista Mineralogica Italiana and Le Regne Mineral. My best and famous heliodor appears in Le Regne Mineral, 2007, in the report of the St. Marie aux Mines mineral show.
I am the source of most of the best vesuvianite specimens from the Jeffrey Mine collected in the last years. Fell free to contact me for any additional information.
