List of gemstones found in the USA

Too often we think of Africa as the primary source of high quality gemstones, and while Africa is a significant contributor, some may be very interested to learn how extensive and diverse are the US gem deposits!

As you would probably imagine, many of the gemstones are from the western regions of the US - Colorado, Arizona, and Nevada would rightly guess most people, but the areas of North Carolina, Tennessee, Arkansas, and even Maine are less well known!

The regular names we associate with gemstones, such as emeralds, rubies, beryl, and sapphires, are all mined in the United States. But there are also many unique stones that are peculiar to the region!

Some of the most important gemstones are listed below and the areas where they are mined:

Main areas for gemstones

  • Opals: - These are mostly found in the states of Nevada, Oregon, and Idaho. Black fire opals are found in Virgin Valley, Nevada. Oregon is also famous for its thundereggs and sunstones.
  • Rubies: - These are gemstones with a rich red color to them. They're pretty rare. One of the places you can find them is in Franklin North Carolina. There are quite a number of areas mining rubies.

In addition to the petrified wood mentioned above, azurite, agate, malachite, and peridot can be found.

Unique to USA gemstones

  • Oregon sunstone would be a very good example. Sunstone has beautiful coppery, red, and burnt umber tones and a bright mood that makes it a great choice for jewelry.
  • Of particular interest is also Ammolite . This is also known as aapoak and is sometimes marketed under different brands. It is mostly found in the eastern areas of the Rocky Mountains and is unique to the US. Its USA status isn't all that makes it unusual, however! Ammolite is a biogenetic gemstone, which means that it was created through natural life processes through the fossilization of mussels! It comes in many shades, but mostly has a layered structure, green, red, and brown.
  • Red Beryl This rare form of beryl is found in the Wah Wah Mountains in Beaver County, Utah

Mining of precious stones

While the US has a good variety of Gem Stone locations, the industry is still relatively small and undeveloped. Commercial production is quite limited. Diamonds, for example, remain the most coveted gem in the U.S. while there are currently no commercial diamond mines in operation. Hence, there is still a heavy reliance on imported gemstones.

Manufacturing in the US is hampered by high labor costs and environmental problems.

A significant portion of US gem funding is run by miners or small commercial businesses with just a handful of employees. This occurs primarily on government land where prospecting permission is given. There are also specially designated gemstone websites where people can pay a fee to search for gemstones.

In the first half of the 20th Century the US was the world's largest producer of tourmaline. Unfortunately this has become more and more expensive and there are no more commercial mines today.

Fine Grades Garnets are still commercially mined in Idaho, and there are three mines that make industrial grenades. More than 11 million tons of industrial garnet, which has many uses, are mined annually.

Although many millions of tons of diamonds are processed annually in the United States, the only active diamond mine is the Crater of Diamonds in Arkansas. However, this is no longer being mined on a large commercial scale.

USA is the world's largest consumer of gemstones

More gemstones are sold in the United States than in any other country in the world. Over 99% of these gemstones are imported as very little domestic products are produced. Most gemstones are mined in developing countries .

Diamonds are the most widely traded and shipped gemstones in the United States. They make up nearly $ 18 billion in the gem trade and colored stones only make up about $ 1 billion. One of the reasons for this is that diamonds are traditionally set in engagement rings.

There is also a large market for synthetically produced gemstones. These are made in laboratories and have the same properties as naturally occurring stones. However, these must be clearly labeled as synthetic in the law,

There is also a growing simulant gem market which is glass plastic "gems" etc. They look like gemstones but have completely different properties.
