Decoding Italian Gold Markings: Understanding 'BH375'

Question
hi i have purchased a chain made in italy with the mark bh375
 i know 375 is 9C but don,t know what bh means is it possable base metal
   regards george

Answer
HELLO GEORGE,

375 IS INDEED THE STAMP FOR '9' KARAT GOLD. THE 'BH' MAY BE A NUMBER OF THINGS. THERE IS INDEED BASE METAL IN ALL GOLD ALLOYS AND THIS COULD BE BRASS OR COPPER OR ANY OF A DOZEN OTHER METALS USED TODAY. SO THE OTHER 63% IS A BASE METAL OF SOME KIND. THE OTHER EXPLANATIONS ARE THAT IT COULD BE A MFG. STAMP OR THE COMPANY WHO MADE IT. THERE IS NO STANDARD DESCRITION OF "bh" THAT I KNOW OF. THANKS

PETER
