by Rose-gold-or-bust » Aug 8, 2019 My grandmother gave me this old pendant close to 20 years ago. It is tarnished and the center stone (garnet?) has fallen out. I know nothing about it. I don’t know if it is silver, diamonds, garnet? Or cheap costume jewelry with fake stones. The metal had worn through from behind the center stone right though to the back. Can anyone shed light on it for me? I truly don’t care if it is just costume jewelry as I keep it for sentimental value but I would love to know more about it just for fun.
