This thin sterling silver ring is made from sterling silver sheet that has been reticulated, meaning it was heated to the point where it almost reached its melting point. This process creates a one-of-a-kind texture that often resembles little peaks and valleys. The ring is made from 18 gauge sterling silver that was cut to a width of 1/8" (or 4mm) and polished to a high shine. Stacker rings like this, when worn with other rings, really make them "pop."  Determining the size of a square ring is a bit difficult, as ring sizers are round, not square, but it is approximately a size 9. 
It works best to put a square ring on your finger by holding it in a "diamond" position with one coner above your knuckle and one underneath it, rather than putting it on with a flat side facing up. Once over your knuckle and in position, rotate the ring into position. My customers often comment that square rings are not only comfortable, but don't move around like a round ring often does.
