925 is the stamp for sterling silver
The idea of using the number 825 on jewelry is that is a grade of silver. Silver that is marked with the number 825 is a lower grade of silver that is not worth very much money.
That probably means it is the 825 th copy if it is somethin like a store bought necklace. If it is gold, iit means it is fake. ---------------------------------------- Most likely it is .825 grade silver if this ring is silver coloured . Still silver but lower grade than .825 sterling
825 RO on jewelry indicates that the piece is made of silver with a purity level of 82.5%.

It is a common standard for silver jewelry to denote its silver content and quality.
The engraving "825 OGC" on jewelry indicates that the piece is made of 82.5% silver, which is equivalent to sterling silver, and "OGC" likely represents the manufacturer's mark or a specific design line. The "825" hallmark signifies that the silver content is slightly lower than the standard 925 used for sterling silver, which is 92.5% pure silver. This marking helps identify the quality and authenticity of the metal used in the jewelry.
Well. 825 stamp on jewelry it is silver alloys; like 725 or 925 stamp is the same silver alloys. Sincerely: L.L.E.P.
10k Edit by Cjulsh 10k is incorrect. 10k jewelry would be stamped 417 which is the amount of gold content. 10k is 41.7% gold. 825 is a lower grade of silver...most silver pieces would have a stamp of 925 which is 92.5% silver. Some pieces will use a lower grade silver 825 or 82.5% silver.
825 Cz likely refers to the metal composition of the ring. In this case, 825 indicates a silver content of 82.5%, and Cz could stand for cubic zirconia, a type of synthetic gemstone often used as a diamond substitute in jewelry.
The term "Thai man 825" refers to a specific standard of silver used in jewelry, where "825" indicates that the metal is composed of 82.5% silver and 17.5% other metals, typically copper. This alloy is less pure than sterling silver, which is 92.5% silver, but still offers a good balance of durability and luster. Thai jewelry often features intricate designs and craftsmanship, making it popular among collectors and buyers. The "man" aspect may suggest a particular style or design associated with male jewelry, but specifics can vary.
"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.
