Please Help Identify Silver Ring 7 Stones

[hilarychloe]

This ring weighs around 3.5 grams. It has 7 clear stones and has the hallmarks in the inside " 925c" and what looks to be "BB". It is used and thinned a bit. I took the best pictures I could to help with this. I have looked all over the web and cannot find it. I would like to know what the "c" means and if the ring is real or fake, I am mostly concerned with the "BB" marks. Thanks for all you help.
