Once upon a time, about 15 years ago, if not more, I found a little stone on the beach. Green,  beautifully.
And the other day, dismantling these very boxes, pulled him to freedom. And I remembered how I once dreamed to create a complete ring from a found stone.
So. 
The ring is ready.
The stone is very very similar to the dark green serpentine, forest color with yellow veins. 
Dimensions - about 30 to 18, the base - 35 to 23 mm, size 18.5, the tire is not fixed in the center, but closer to the edge, so the ring is very naturally and comfortably sits on the fingers.
