Colorado is regarded as one of the most beautiful states in the country with the iconic Rocky Mountains forming a background for an outdoor escape. Beneath it all, lies a hidden world of Colorado gems that turns the state into one of the most sought-after destinations for crystal collectors of all ages. From the official state gemstone, Aquamarine, to Topaz and Smoky Quartz, the Rocky Mountains boast some of the most incredible gemstones you can find anywhere on the globe.
Here are some of the most notable gems found in Colorado:
Aquamarine
Named Colorado’s state gemstone in 1971, Aquamarine is a beautiful blue-green variety of beryl found in the highest mining location in the US. The gem is highly sought after for its amazing blue hues and is an excellent choice for daily wear. It is the official birthstone of March which makes it a perfect gift for anyone with a birthday in the third month of the year.
Topaz
Highly prized by collectors, Topaz found in Colorado is known for its clarity, sharp crystal shapes, and natural hues. These gems form in cavities within granite and are naturally found as colorless, pale blue, sherry-brown, or peach-pink crystals. It measures an 8 on the Mohs hardness scale, making it durable enough for everyday jewelry.
Amazonite and Smoky Quartz
The Amazonite and Smoky Quartz pairing is famous for the stunning contrast between the teal-blue Amazonite and the dark Smoky Quartz. The gems often form together in underground pegmatite pockets, growing with cleavelandite and albite. Prime specimens can often be found from well-known locations around the Crystal Peak area.
