OSSA jewelry is a project of Nikolai Cheremnov, a designer from St. Petersburg.
All jewelry is made by hand, many of them are one-of-a-kind. Each ring has its own unique pattern. Cracks that cut natural stones in half, faults and relief patterns that evoke associations with mountain ranges or solidified lava - rings that are ideal in their imperfection.
The technology for making jewelry with cracks as well as setting broken stones is the author's own invention and has no analogues in the world.
