Sapphire Fun Facts:
Sapphires are gem-quality pieces of the mineral corundum, and is mined around the world - most North American sapphire comes from Montana.
Sapphire comes in pretty much every color of the rainbow (except red, technically, since red corundum has it’s own gem name - Ruby). However, sapphire is most commonly associated with deep blue.
Most natural sapphires are heat-treated to make them look more blue and disguise inclusions.
Artificial sapphire is identical to natural sapphire, except it can be made without flaws or inclusions. Sapphire is the third hardest mineral, and cheap artificial sapphire is used in lasers, ultra-thin electronic wafers, and shatter-resistant windows for armored cars. Some Apple Watches have screens made from “sapphire glass."
Besides being the birthstone for September, Sapphire is also the gemstone for both 5th and 45th anniversaries. So, if you have one of those coming up - happy anniversary!
