This square shape ring is a good gemstone ring choice for both men and women. The fairly large ruby-zoisite gemstone (5/8" x 5/8") is set in a simple sterling silver framework. The top of the ring measures 3/4" x 3/4" in size. This purple-green gem is one that will never go out of style, and the simple squared design of this ring will allow it to be classically fashionable forever.
