Canadian Rock & Mineral Slabs for Cabachons & Lapidary Arts

Who we are: We are a family of Rockhounds who not only love to collect rocks & minerals, but also like to make things from what we have collected. We are involved in a number of small enterprises related to our interests & because we are retired, we dabble in a number of things - including the lapidary arts.
What we sell: We are selling slabs of rocks & minerals of Canadian specimens. We have noticed that there are many sources of beautiful slabs online, but that not many of these slabs are Canadian or decorative stones. For that reason, we have decided to offer our self-collected Canadian slabs for sale.

Our Customers:  Our customers are people who want to make cabs or other decorative items out of rocks & minerals that are not commonly available. Because our specimens are Canadian, our slabs are of interest to people who either collect Canadiana or who want to expand their collection to include rocks & minerals from Canada.
Shipping: Because we live in Canada (just north of Toronto in Ontario), shipping slabs anywhere is very expensive. It just doesn't seem fair that the cost of shipping is half or more than the value of the slabs themselves. However that's the way it is and when the cost is factored in to the final cost of a finished cabachon made out of a unique material that is not that common, then the price of buying online from us is justified. Since we are not doing this as a major enterprise, you will not find us at any mineral shows however if you are ever in the GTA, we would be happy to have you drop by & save yourself the shipping cost.
