A letter from Jack Sliemers
Owner of the Moss Rock Shop

Hi there! My name is Jack, and welcome to the Moss Rock Shop!

This all started when I was 10 years old in 1944.  I contracted Rheumatic Fever and doctor’s orders were to lie in bed for two years.  My four sisters and brother regularly took day trips to the mountains outside of Denver and I would ask them to bring back rocks, since I couldn’t go.  With this, I accumulated quite a pile of “pretty” but largely unimpressive rocks.  As the years passed, and I gained control of my own acquisitions, my collection grew more sophisticated, as did my knowledge on the subject.  

As an adult I went on to earn college degrees none of which have much to do with earth sciences; these degrees however instilled in me a thirst for learning which led to my extensive growth in lapidary arts, paleontology, mineralogy and jewelry making.  

After 65 years of experience and owning two rock shops (in Morrison and Englewood, Colorado) and having done many Gem and Mineral shows, it’s way past time to liquidate - in fact, it occupies the number one slot on my “bucket list”!  

This hobby turned into a business, then into a home business and now into a liquidation sale via website. I will only be selling from what I currently own; what I do have I will try to keep below market price. 

Below is a sampling of the tasty items that I will be offering, some in great quantity despite their rarity worldwide:

  • Minerals
  • Fossils
  • Cabochons 
  • Faceted stones
  • Lapidary rough (tons)
  • Carvings
  • Quartz crystals and clusters from my mine in Arkansas

Some rocks will be by the piece, some by the flat, some rough by the pound, other things will be sold as a “Lot”, but in the end, they will be SOLD!
