For sale is this great, natural jade brutalist sterling silver ring. It is possibly handmade and dates to the Mid Century. There are some touchmarks inside the shank, but no signatures. It has been carefully acid tested and is guaranteed to be 0.925 sterling silver. The jade bead measures 6mm diameter, ring is a size 6 1/4 and it measures 3/4" from north to south. Because of the weight of the piece, 17 grams, I believe it is solid sterling (even the beads on top). No damage or repairs.
