Mineral Weather by Olhovsky

Far from ordinary, the founder of the brand Alexander Olhovsky uses bronze, brass, and raw natural stones. Whichever stone nature has created goes straight into the ring. And as you understand, nature doesn't repeat itself, so each ring is one-of-a-kind.

The stones are as unique as they are mysterious: azurite, morion, zultanite... The names of the materials sound like a list of ingredients for an alchemy potion.
