FAS Makers Mark

by Nancy Janeliunas

FAS is not Fused Alloy Silver. What the FAS letters stand for and who the manufacturer actually was brought up during a jewelry discussion relating to an item in question. An online article was pointed to FAS being identified as Fused Alloy Silver by a Chinese seller or sellers on items that were found to be solid sterling silver. There is also confusion with it being Fantastic Antique Silver Company. Its very easy on the internet for one blog posting to be picked up and followed by all who also seeking information. Soon everyone follows that lead and it appears to be a 'fact' to the point that all jewelry marked FAS is now said to be made by Fused Alloy Silver or the Fantastic Antique Silver Company when you do an online search.

· FAS is an international trademark for :

Registered # 823389 - FAS

Designs by FMC, Inc.
1533 60th Street
Brooklyn, New York, NY 11219 (US)

Designs by FMC are wholesale designers of Jewelry, namely bracelets, pendants, earrings and rings and costume jewelry since 1993. Their jewelry is manufactured overseas and imported back for sale in the US and sold by mass merchandising channels like HSN, Amazon and their own web site. In addition to sterling silver this maker also is a large producer of gold and silver plated fashion jewelry also marked FAS but without the metal fineness noted. This is not saying an overseas maker did not steal their trademark and use it on fake silver as one particular blog has alerted readers. However it cannot be assumed all pieces with the FAS trademark is one and the same as the alleged Fused Alloy Silver company by Chinese sellers. There is a very similar FAS trademark in the Chinese registered trademarks database without the horizontal line across the ‘A’ which may be confused with the US maker so pay close attention to how the 'A' looks on the mark.

Here is an original Designs by FMC hang tag with the FAS trademark



I recently acid tested something labeled as fas925. I tested it several times and it kept coming out a brownish red which would indicate about 80% silver instead of dark red (92.5% silver which is sterling). So perhaps, at least in this particular case, the Sterling Silver was mixed with an alloy, making it only about 80% silver instead of 92.5%. I don't think this was just plated with sterling because it was scratched several times on a scratch stone to do the acid test with the same result.
I recently ran upon a "FAS" ring. It is INDEED Sterling. It is marked 925 FAS on one side, and on the other, it is marked Thailand CZ. I acid tested it to be sure, and it acid tests as 925 Sterling Silver as well.
Something marked "925 FAS" is PLATED with 925 silver, not solid sterling silver. Given that ALL sterling silver is "alloy silver" it seems to me that if it does in fact stand for "fused alloy silver" then it means exactly what is says: An item made out of some other metal is "fused/plated" with an alloy of silver (not pure silver). The 925 is there to tell you what purity the "alloy" plating is made from.

So in the end, something marked "925 FAS" is likely just a copper item that is plated with .925 silver. Regardless, anything with this marking should be considered fashion jewelry with no real precious metals content.
Thanks for this information.I inherited a ton of jewelry, some real and costume jewelry that I'm researching and learning the history of which is my favorite hobby.I just want to know if I have something that is very valuable and learn more about where and who made all of it.
