KRISTALLE is a buyer of fine mineral and gold specimens. We are interested in buying entire mineral collections or individual specimens. Antiquarian books and instruments are also of interest.


Please read the following VERY carefully…

this will give you some guidelines to follow before contacting us.

Please look through our website first to see the quality of minerals we sell. We are interested only in well-crystallized minerals – NOT rocks

What is a Mineral??

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids. Some rocks are predominantly composed of just one mineral.

These are ROCKS

These are crystallized minerals

We prefer that you send photos with your inquiry about selling your collection.  Email us at with a couple photos of what you consider your BEST items. Please give sizes of specimens, locality, asking price, and any provenance.

We are NOT interested in rocks, polished pieces, carvings and the like – we ONLY buy well crystallized specimens for collectors and museums.


Please be aware that we receive HUNDREDS of emails throughout the year from people wanting to sell their items, but we only buy about 1% of what is shown to us.

 After looking at the photographs, if it is something we are interested in we may want to visit you and see your collection in person to offer a more accurate appraisal. We have the ability to market at both the retail and wholesale levels and we are one of the few companies that are able to pay cash upfront for the right specimens. We offer the utmost privacy in our dealings- we have purchased numerous collections for which privacy was a concern and we have never revealed those names.

Kristalle has been involved in the purchase and dispersal of most of major mineral collections to come on the market, from small private collections to large museum collections.
