Blue Sapphire Rings

Blue sapphire is corundum, 9 on the Mohs scale and second only to diamond, so it is made for everyday wear. It is the September birthstone. Most sapphires are heated to improve colour and clarity; every listing states the treatment, and unheated stones are labelled as such.

  • I absolutely love this 1930s sapphire rose cut from Roho Jewels! The sapphire is even more lovely than I imagined, and I can’t wait to make something with it. Leander was super prompt and communicative, responding to any questions that I had quickly and shipping the stone out right after I purchased it. I can’t recommend his shop enough - thank you so much, Leander!
