Buy gems by country of origin. The United States is not known as being one of the important gemstone producing countries, but this was not always the case. In fact, back in the first decade of the 20th century, the US was the world's leading producer of fine tourmaline, with important tourmaline mines located mostly in Maine and California.
Commercial gemstone mining in the US is still active in several other states. Surprisingly, the top state (based on total produced value) is Tennessee. This is because Tennessee is home to the American Pearl Company, which operates the only freshwater pearl farm in America. Other important states include Arizona, Oregon, Montana, Nevada and Arkansas. Hawaii is also known to have some of the world's finest coral, but due to strict coral laws, Hawaiian coral is not allowed to be exported in any amount. There are many fine American gemstones, but they are becoming increasingly rare, especially when it comes to fine Nevada turquoise and Oregon sunstone, which are two of the most sought-after USA gemstone types.

Gem Select has a great selection of products and it is very easy to navigate the website and find what you are looking for.
Gemselect had such a fantastic selection of all gems I could want, in pairs, lots, or singles, and if I wanted some gems to be just 1/10th of a millimeter bigger or smaller, they had that variance also, which is massively helpful for the specific pieces I make with their gems. I could even select different qualities of clarity and tone, which really helps my projects a lot too. I never regret a purchase made from gemselect, they help me run my custom jewelry business better with their products.
I was looking to get some stones to help turn into a necklace for my daughter, but other sites didn't have exactly what I wanted, I found it on GemSelect though, and I think it will turn out really really well!
Once again, the picture of the gem shown did not match the stone I received. I believe they are the same stones, but the pics shown were enhanced some way to show the beauty and coloration of the stone. I could NOT see the coloration. I should have realized that would happen.
