Identifying and Valuing a Thai Silver Ring with 'NFL' Marking

Question
My aunt passed and I got a bunch of her jewelery. This one particular ring intrested me. It is big and gotty, but the stones almost look real. It has the number 825 in the band, it also has the letters that appear to say NFL, and it says it is from thailand.) I hear that the 825 is the silver mark.  I have heard from my other research that diamonds arn't usually set in sliver, but is there any chance? or if not can you tell me an estimite on what is may be worth?

Answer
Hi Cheryl,

It sounds like you have all facts down that you need. There is so small a chance that those are diamonds so forget that. And what you want me to do is make up a value with no basis. So I can't do that either. I have no idea what it weighs so I would have to make a guess. So not much help from me. Good Luck.
