Heat-Treated Sapphires

We have a great selection of heat-treated sapphires. There are several benefits of the heat treatment process, including its ability to enhance the gemstone’s clarity and develop its color. Heat treatment is done intentionally to change the color of the stone and evaporate the rutile needles, also known as “silk,” in sapphire stones. View our selection below to see our heated Montana sapphire. To simplify your search, use the filter feature to shop by size, shape, and color. Here at Americut Gems, we pride ourselves on selling sapphires that are mined, cut, and polished in the United States. Every purchase of our heat-treated sapphires will also include quality gemcutting reports that confirm the stone’s precision cut and documents of its dimensions and angles.
