The 2020 Denver Gem and Mineral Show was a Success! While it was a little different this year with the current circumstances, we still had a great show and good attendance! We want to send out a big thanks to all of our friends and customers who visited us at the Crowne Plaza Hotel as well as our Open House and Wholesale Warehouse at Collector’s Edge Minerals, Inc. in Golden. We also want to thank everyone for doing their best to comply with local and state guidelines regarding the pandemic during this event, we hope you are all staying safe and healthy!

This was our main display case at the Denver Crowne Plaza Airport Hotel.


We had some spectacular new minerals to offer this year . At the “Show within a Show” in the Crowne Plaza Denver Airport Hotel from September 11th through 15th, we had a small display with some of our new retail specimens. The show was reduced greatly in size due to Covid-19 precautions, but we were still able to catch up with 60 other vendors in the hotel, and had a great overall turnout of visitors and long time customers.

We also had the opportunity to debut many new Rhodochrosite specimens mined in July 2020! After 4 years of hard work, miners exploring in the Detroit City Portal at the Sweet Home Mine have discovered a pocket zone with new high-quality, cherry-red rhodochrosite.

These new Rhodochrosites made their first show appearance at our Open House in Golden!


We were able to display 2 shelves of these rhodochrosite specimens pulled from “Zack’s Pocket” and “Deano’s Pocket” out at the Crowne Plaza, and many more at our Open House.

We took lots of precautions for the show to ensure a safe environment for all of our visitors.


Back in Golden at Collector’s Edge Minerals, Inc., we were joined by The Focal Crystal, a top-quality dealer of fine mineral specimens, from Houston, Texas. They set up at our main office with many great specimens of their own.

At our Open House, we had lots of high-end retail rhodochrosite specimens to choose from. We also had our first “show debut” of the GP Rare Earth Collection of Milwaukee, Wisconsin consisting of over 1,200 spectacular mineral specimens – particularly gem crystals from around the world.
