What is mixed in with Rolex 18k yellow gold

So Rolex makes their yellow gold watches out of 18k which is 75 percent pure 24k. The rest is other metals to give it more strength. Anyone know the ratios of the last 25 percent of metals used in their 18k and the percentages of each metal? Anyone had their gold Rolex Xrayed?

I'm guessing 3N, 12.5% silver and 12.5% copper.

Someone must know a jeweler or metal place with one of these. Be pretty simple to figure out with the right tool.

I was surprised to learn how much those cost. Even a used one is around $15k.

Not surprised. It would be absolutely indispensable for some businesses, like those who could lose that much on a single transaction with a counterfeit hallmark.
