John Cornish Minerals 

Picture
John Cornish Minerals has been sharing the excitement of crystals and fossils for over 20 years and we’re looking forward to the opportunity to share it with you too!

Our Denver Show offering will present a varied palette of specimens worthy of every budget's consideration. We’ll offer crystal specimens gleaned from exotic localities found round the globe and those which we’ve mined ourselves nearer to home. In addition, we’ll showcase exquisite polished lapidary treasures and we’ll have an assortment of books and tomes for those whose knowledge thirsts for the written word.

Our personnel are knowledgeable and we are willing to help you find those unique personal treasures sure to enhance your day and smile. We look forward to meeting you at the show!

Special Pre View For This Year's Show!
​
John Cornish Minerals will be presenting a sensational *NEW* lot of Australian Crocoites and Azurites, the largest and most comprehensive selection of these specimens offered during the Denver Shows.

​Also,  *NEW* specimens of Barite and Calcite fresh from Iowa's, Linwood Mine. From Johns' Rat's Nest claim in central Idaho, we'll offer a diverse group of Mordenite and Heulandite specimens in subtle whites and pinks.

Our treasures will be sure to please during the upcoming Colorado Mineral and Fossil Show on September 7th - 15th at the Crowne Plaza Hotel. Stop by our booth, #C-13, just inside the Main Retail Ballroom door. We're looking forward to seeing you there and sharing a smile with a big hello! 

 ​John Cornish Minerals is located just inside the door near the eastern Main Convention Center entrance, one of the very first dealers whose booths you’ll see. Visit all of the dealers at the show but make sure to stop by us first to see the new things we’ll have for you and your store’s inventory or personal collection.  John Cornish Minerals has been regularly featured on the excellent BlueCap Productions series What’s Hot In Tucson.
