Pink silver tone pendant jewelry

Pendant is in good condition and kept in a clean smoke free home. I am not sure if this is a stone. It was very cold and warmed quickly in my hand and registers glass on my presidium II. It may be made to look like a gemstone but actually glass. Pretty striation design, shades of pink, 5mm round bail plus attached 1/2” link/additional bail. With frame and bail it’s 1 2/8” X 6/8”. It’s in very good condition. Some photos look like it has scratches but that’s a reflection. Back has 2 small marks. #pendant #silver-tone #pink #glass #jewelry
