Kappa Delta Ring

Kappa Delta ring which is adjustable to fit different sizes. Does not include any bag/box. Condition: Good used condition and was just polished so it is shiny. The ring has been worn several times so there are a few minor dents/scratches. Other: I am not sure the metal material. I was told that this was sterling silver when I purchased it, but I do not see any markings on the ring itself
