This is a kyanite measuring 11 x 8.5, set in a sterling silver bezel. Kyanite is untreated so the blue is completely natural. It's a very delicate stone, hence the bezel and thick basket. It's unusual because it has two Mohs ratings - the long crystals have a Mohs hardness of about 4.5 to 5 if tested parallel to the length of a crystal. However, it has a hardness of 6.5 to 7 if tested across the short dimension of a crystal.
The crystals tend to grow in elongated shapes, hence the long-ish oval.
I adore the heavenly mid-blue of this ring, and it makes me feel as if I'm wearing a gorgeous Kate-like sapphire, for significantly less money. I also like that kyanite receives no treatments at all, and comes out the ground this amazing (to me) color.
Enjoy the photos!
