This is a replica watch forum my man. If you're looking to fool laymen head on over to canal street. I hate to break it to you but anybody with some experience in the watch/jewellery field could easily differentiate between SS and white gold, much less the members of this forum. Its the kind of thing that jumps out at you once you start noticing it. Just head on over to any boutique/jeweller and get educated before embarrassing yourself more online.
Back in the early 80s in the U.S., the Hunt Brothers tried to corner the Silver market, by buying and hoarding silver, which in turn drive up the price of gold as well.
Pawn shops and Gold and Silver stores and individuals started renting storefront and hotel suites placing ads in papers announcing they were buying gold and silver. The next day there would be lines of people waiting outside with gold jewelry, silver sets of knives and forks platters and silver coins. I started working off duty at a few of those locations them paying me $25 an hour, which was huge money in 1981.
When they transitioned into making really big money then made me a buyer at $50 an hour, checking out the gold and silver to see it was plated, and in the case of gold what carat it was, 24, 18, 14 or dental gold.
We did this with a wet stone and muriatic acid, running lines of verified samples of the different carats across the stone, then a line of the seller's sample. A drop of acid then ran down all the lines and when it dissolved the lines, the same seller's sample would dissolve correspondingly with whatever the correct carat was.
I did this for almost 4 years and ended up working for one of the Smelters who all these buyers would turn over their purchases to. The outside buyers could turn a 30% profit, cashing a check written out to a phony name that the Smelter "Suppo Smelters" would call their bank and tell them to cash the check, the guy was then went to the bank and cashed the check and pocketed cash with absolutely no paper trail for the IRS..
So rather than "Educating myself and embarrassing myself," I think I have a teenie tiny bit of knowledge about White Gold and Stainless Steel, but you see, back then there was no such thing as 904L stainless, so visually you could tell the difference immediately. Not so much today, but the weight difference would be a dead give away, but unless it was a side comparison today, I doubt many could tell the difference just visually!
