Stamed 417 MW?

Hello: I was wondering if I could get a question answered that I
have not been able to find on the net. I have a piece of
jewelry - a lovely garnet cross that appears to be set in gold.
On the back of this piece it says 417 MW. Can you tell me what
that means?? I was expecting 10 kt gold, etc. and have no idea
what this means. If you can help I would
appreciate it. Thank you - Glenda

Hi I expect it states the gold content as being 41.7% (exactly
10Kt.) and MW are the initials of the manufacturer. This system
is used extensively in Switzerland. Regards, Mohamed www.Tz-gems.com

Come on, Glenda, do the math - 10 (as in “10 K” ) divided by 24
(as in pure gold) equals .416666666… (ad infinitum - call it
.417 for convenience sake.) “417” on a piece says"10K" as “585”
says “14K,” “750” = 18K and so forth. “MW” is probably someone’s
trademark - as Fedral law says you may not sell any jewelry,
etc. with a quality mark without a trademark nearby declaring
who says the piece is that quality. Mike
