The ring has a second mark that I believe is Bahamas (last photo), and is about a size 7.
It was authenticated and appraised in the Virgin Islands in 1999 by the Colombian Emeral International company, and you will receive that paperwork.
Shipping: I will ship in the generic black velvet ring case shown with additional insurance and signature required to the eBay authenticators in a clean recycled box with large cushion bubble wrap and shipping paper, with the paperwork on the bottom. Thanks for looking.
