GREENSTONE CUSTOM MINERAL BASES

Dear customers,

Regrettably, as of August 1, 2026 we are only making custom bases for existing customers who have ordered bases from us in the past. The reason is that we have decided to retire and wind down the company. We will continue to make bases for our existing customers until our supplies run out or any of our equipment fails. Once that happens we will end the base-making part of the business.

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 890 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
