List Of Gemstones Found In The USA

List Of Gemstones Found In The USAWe all too often think upon Africa as the world’s main source of quality gem stones, and whilst Africa does contribute significantly, some may be quite interested to learn just how extensive and diverse the deposits of gem stone are in the USA!

As you would probably imagine, much of the gems are sourced in the western regions of the USA – Colorado, Arizona and Nevada would rightly be most peoples guess, but lesser know are the areas of North Carolina, Tennessee, Arkansas and even Maine!

The regular names that we associate with Gem stones, such as Emeralds, Rubies, Beryl and Sapphires are all mined in the USA. But there are also many unique stones that are peculiar to the region!

Some of the main gemstones are listed below and the areas in which they are mined:

Main Areas for Gemstones

  • Opals: - These are mainly found in the states of Nevada, Oregon and Idaho. In Virgin Valley in Nevada there are black fire opals. Oregon is also famous for its Thundereggs and Sunstones.

  • Rubies: - These are gemstones with a rich red coloring to them. They are quite rare. One of the places you can find them is in Franklin North Carolina. There are quite a number of areas mining rubies.

  • Jade: - This gemstone can be found in both California and Wyoming. Wyoming in the mid 1930’s was named the Jade State.

  • Emeralds- This beautiful gemstone can be found mainly in North Carolina. Some of the rarest and biggest Emeralds can be found in this state. The Carolina Emperor which is one of the largest Emeralds found in North America came from North Carolina.

Unique to USA Gemstones

  • Oregon sunstone would be a very good example. Sunstone has lovely copper, red and burnt umber tones, and a glowing disposition, that makes it a great choice for jewellery.

  • Ammolite is also of particular interest. This is also known as Aapoak, and sometimes marketed under different branding. It is found primarily in the Eastern areas of the Rocky Mountains and is unique to the USA. Its USA status is however not all that makes it unusual! Ammolite is a biogenetic Gem stone, meaning that it was created by natural life processes, through the fossilization of shells! It comes in many shades, but most often has a layered, green, red and brown structure.

  • Red Beryl This rare form of Beryl is found in the Wah Wah Mountains of Beaver County, Utah

Mining of Gemstones

Whilst the USA has a good diversity of Gem stone sites, the industry is still relatively small and undeveloped. Commercial production is fairly limited. Diamonds for example, remain the most sort-after gem in the USA, whilst there are currently no commercial diamond mining operations in place. As such, there is still a heavy reliance on imported gems.

Production in the USA is hampered by high labour cots and environmental concerns.

A significant portion of USA gem stone mining is done by amateur miners, or small commercial concerns with only a hand full of employees. This is primarily done on Government land, where permission to prospect is given. There are also more specifically designated gem sites where people can pay a fee to search for gem stones.

In the first part of the 20th Centuary the USA was the top producer of Tourmaline in the world. Unfortunately this has become increasingly expensive to mine and today there are no longer any commercial mines.

Fine qualities Garnets are still commercially mined in Idaho and there are three mines that produce industrial garnets. There is more than 11 million tons a year mined of industrial garnet that has many uses.

Although many millions of tons of diamonds are dealt with annually in the States the only active Diamond mine is the Crater of Diamonds in Arkansas. However this is not mined any more on a large commercial scale.  List Of Gemstones Found In The USA

USA is the world’s largest consumer of gemstones

More gemstones are actually sold in the USA than in any other country in the world. Over 99% of these gemstones are imported as there is very little domestic production. Most of the gemstones are mined in developing countries.
