This is a very unusual mid century modern ring made of sterling silver with 3 sides of inlaid petrified wood. I don't know if it is a "one of a kind," but if it isn't, its awfully close. The ring is a size 8 and the sterling silver is solid. The measurements are as follows - the top is 1 1/8" x 3/8", the sides are 1" x 3/8" and narrow down to just over 1/8", the bottom is 1/2" x 1/8."
The inside top is marked 925 for Sterling and has been acid tested to insure sterling content. The sterling is solid. The petrified wood panels are in good condition, sort of a matte finish from being worn, but no missing pieces or damage. The patterns in the wood resemble the rings of a sea shell, kind of a swirling design that are the rings of a tree branch.
The weight of the ring is .30 ounces or 7 grams.
