Diamonds are not stamped: perhaps the metal setting is stamped. Take your jewelery to a local jewelery shop and ask that the diamond be tested.
There is zero relationship between the stamp on jewelery metal and the stones set in the metal. A local jeweler using a probe can answer your question.
925 is the stamp for sterling silver
not sure about the NF but 925 is silver i know that much for sure!!
NF 925
(Cwe) Charles winston edition (cz)cubic zirconium (925) sterling silver (nf) nickel free..
Your ring is definitely real, as it is not imaginary. It is also a genuine silver ring. The 925 is the silver content in the ring. The other 7.5% is another metal alloy, usually copper. 925 is also known as sterling silver. The country is where your ring was made.
The number 925 may indicate a purity of the silver. The identifier 750 nf may be a design number, catalog number or other identifier best explained by the designer/ manufacturer.
"925" means it is sterling silver or a 92.5% purity of silver. NF is a hallmark of the silversmith. I am trying to find nf now. I will post when I find it. From LCsocal: I am not sure that is correct, otherwise NF would be the busiest man in Thailand. I believe the "NF" indicates "nickel filled" with sterling silver plating. This would be consistent with the hallmark GF 14K, which means gold filled--an alloy of some sort with 14K plating. You'll note that the silver pieces from Thailand with the NF 925 hallmark are usually exceptionally well priced and this explains why. I am certain that the NF stands for nickel free as there are many who are not able to have nickel in there jewelry as they are allergic to it, and as the sliver has alloys added to it, the other .75 of the 9.25 as it is a make up of other metals to make it hard and useable for things like jewelry.
