14k gold ring with purple crystal

This ring is US size 6.5 It is 14k gold with a purple pear shaped cut Austrian Crystal Gemstone. This ring weighs .07 ounces. This ring is in good condition. It was part of my mother's old jewelry kit and it originally had no stone so I added one in there from my mom's collection that I believe is an Austrian Crystal, fine cut glass or zircon at best.
