It is from a Jamaican Designer Nataliya V Collister
NVC is a Maker's Mark, indentifying the designer. In this case, NVC stands for Nataliya V Collister. While authentic NVC rings can certainly be true silver, the NVC itself does not mean "sterling silver" as this person suggested. To answer your question, it depends on the ring itself. NVC rings are typically affordable, but there are more expensive styles. I suggest taking your jewelry to a reputable jeweler for an appraisal, if you want a realistic and accurate dollar amount assigned to it.
I found a unique ring with the markings of 925 NVC 6...925(92.5%) means it is sterling silver and is the purest form of silver typically used in Jewelry making...The only thing I have been able to find on NVC is that there is a Distinctive handcrafted Jewelry designer named Nataliya V Collister...among other things she exclusively uses this type of silver....don't know what the "6" means yet.
It means somebody stamped "NVC" on it.NVC are the initials of a particular jewelry designer (Nataliya V Collister), but marks of this type are among the easiest things to fake, so it doesn't necessarily mean that it was actually designed by that person.
