Marboux Vintage Jewelry

Hello
I have bought a large amount of vintage jewelry from an estate sale and there is a bracelet that looks to be good quality, the metal looks brighter than sterling, so I was wondering if it were white gold or platinum? The mark is Marboux 672 the 672 is confusing? What does the word Marboux mean? Thanks, I appreciate your help
