Beautiful gemstone ring, costume jewelry, approx. Sz.8

Brand new never worn, gem stone ring, almost looks like the family birthstone rings, ruby (or garnet) peridot, diamond and tourmaline (or light pink amethyst). Costume jewelry, so the band could be gold dipped nickel or stainless steel. Feels quality and has a nice weight. Around a size 8 or 8 & 1/4, doesn't fit any of my fingers I usually need a 6 or 6.5.
