Montana sapphires, especially Montana yogo sapphires, have been acknowledged worldwide as some of the highest quality sapphires available. Competing with even the most brilliant Sri Lankan stones, these gems with their spectacular rainbow of colors and pristine clarity are a must have stone.

Most of the sapphires from Montana are a pale green to blue-green when they are mined, with very limited numbers of deep blues and other fancy colors such as yellow, orange, violet and pink. Montana sapphires are members of the corundum family, which includes both ruby and sapphire. Sapphire has a hardness of 9 on the Mohs scale and it is quite tough, making it perfect for engagement rings.
We put hundreds of loose, individual sapphires out in the showcase at any given time so that you can come in and choose the sapphire that you love. Each stone has its own form of brilliance and once you find the perfect one, we can build a setting around it.
Faceting is a grinding and polishing process (commonly called “cutting”) that turns little rocks into the beautiful jewels we know and love. Each stone is hand faceted using a grind wheel. It takes a very specific eye, attention to detail and patience in order to become a master cutter. Faceting commonly is accompanied by heat treatment for sapphires.
Sapphires have been known to occur in Montana for over 150 years and have been actively mined there for more than 100 years. Originally starting with the British owning the mines, it is even rumored Princess Diane's sapphire is a Yogo Sapphire.

Heat-treating is the process of heating sapphires to near the melting point, in order to hopefully improve color and/or clarity. Almost all sapphires and rubies worldwide are enhanced this way. It is completely permanent with the goal of enhancing the colors within the stone. Standard heat-treating is generally accepted in the gem industry for the processing of sapphires. One of the best parts of Yogo Sapphires is that they are not heat-treated, and are naturally that beautiful. We are happy to carry a wide variety of stones at Coins and Carats for you to choose from.
Because of our massive selection, we do not currently have photos of all of our individual stones. However, feel free to come in and find one that you love and we can choose a setting based around it. While on the website though, you can explore our sapphire settings and designs in our catalog to see what designs you prefer, and we can place a Montana sapphire in it directly in our store.
