Tired of browsing countless websites looking for a particular mineral? The Dakota Matrix website allows each registered customer to submit a want list (minerals you have to have in your collection). The Dakota Matrix website will then automatically send you TWO notices by email notifying you when we are getting ready to post one of your minerals and then again when we post a mineral on the website. Click here to learn about the Mineral Want List. It's an easy three step process!! How wise is that?
