New 925 Silver Ring & Earrings Set

Received as a gift several years ago. Never worn. The ring is not my size. Zoom photos show no scratches or west of any kind. It is a beautiful set. I’m not sure what stone is used;I thought it might be a tigers eye, but there is not rippling so I can’t say for sure. Let me know if you know! :) The ring is an approximate size 7.5, maybe 7 3/4, see size post photo.
