      Created in 2001, Thames Valley Minerals (TVM) is the parent company of e-rocks.com. Originally a 'regular' website with sales pages, it has now traversed into the world of online auctions with e-rocks.

      Run by Mark, Christian & George Wrigley, TVM auctions provides us with some much loved hands on time with minerals. We regularly list specimens in the numbered auctions as well as adding seller pages and blogs to the site.

      Follow us here to keep up to date with our activity which could be about anything and everything mineral related as well as the odd picture of the family dogs!
