I picked this ring from an outdoor shop by a bazaar in Tula, Russia.
The ring itself is handmade of silver, adorned with a beautiful dark moonstone. The cracks in the stone cast beautiful shades in the reflection, and from the right angle, the stone seems to have black and white shimmer. I’ve never seen anything like it.
Excuse my rugged hands.
Edit: I later found out this is a labradorite.
