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

NOTE!!

Please read the following VERY carefully before contacting us…


 We are only interested in undamaged well-crystallized minerals – NOT rocks.

Ask yourself, would a MUSEUM display this? 

Please look at the highest priced items on our website first to see the quality of minerals we sell.

Our website is only a small representation of what we sell – we only go up to a few thousand dollars on the website, but our main customer base is in the thousands to TENS of thousands. Therefore, the best examples of the quality of specimens we are looking for are what we display and sell at mineral shows around the world. This is our focus. For more examples browse our Show Reports and check out the below photo

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

Examples….

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.

Next Steps

After reading the above and looking through our website and mineral show photos, if you think you have top quality specimens we might be interested in, contact us.

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

We may then ask for more information including:

  • What does your collection consist of? For example, do you mostly collect Azurite? Do you favor English minerals? Maybe you have a variety?
  • Any specimens with notable history? Where do you primarily get your specimens from?
  • The size of your collection (how many specimens? general sizes of the specimens)
  • Is everything labeled or documented?
  • How are they currently organized? Are they boxed or on display? Are they mounted?

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.
