GREENSTONE CUSTOM MINERAL BASES

Dear customers,

Regrettably, as of August 1, 2026 we are no longer making custom bases because we have decided to retire.  If you are an existing customer and really, really, really need a few bases done then we might be able to accomodate you if we still have functioning equipment and supplies to do it.  Please contact us first to see if we're able to help you out.                 

It has been our honor to be a part of your mineral collection over the years, and we are very grateful for your business and the opportunity to provide this service. As of this writing we have made exactly 908 custom bases for customers. When combined with the bases we have made for our own mineral inventory the total is probably getting close to 2000.

The good news, however, is that we have posted a very long and detailed tutorial video which shows you exactly what your process for making this bases is, so hopefully someone else can carry the torch.

Sincerely,
Brian Greenstone
