This is a fabulous vintage ring which was made of sterling silver and hallmarked as such.
The ring is also hallmarked TAXCO Hencho en Mexico along with a very hard to read artists initials of EA_. Not sure what the last letter is. I also cannot make out the eagle assay mark.
The ring is a size 6 1/2 and is in VERY GOOD condition! It measures 3/8" wide and weighs 5 grams.
