Africa is the main source of diamond as well as other quality gemstones. But did you know that the USA also contains extensive and diverse deposits of gemstones?

The Bottom Line

As compared to other parts of the world, gemstone production in the United States is quite low. Although there are great sites for gemstone production, the industry is still undeveloped and small. It is mainly because the cost of opening a mine and labor is quite high and there are government regulations as well. However, the good news is that some fine quality gemstones are still mined in the country. If you want to buy gemstones mined in the United States, it is best to buy them from a trusted online platform.
