Platinum is commonly marked with 950 or 850 so check your jewelry: If a piece of jewelry contains at least 950 parts per thousand of pure platinum, it can be marked simply platinum. If an Item have at least 850 parts per thousand of pure platinum, it can be marked with the amount of pure platinum and the word platinum or an abbreviation (i.e.: 850 platinum, 850 Plat or 850 Pt.).
Silver is commonly marked with 925 for sterling silver and 999 for pure silver. There are other lesser grade marks for silver but they are uncommon. There are some low grade silver marks out there though. I happen to have a silver belt stamped 800 silver.
Some jewelers stamp the percentage of gold rather than the typical 10k, 14k, 18k, 22k, 24k.
If the piece is real gold it is easy to convert the percentage to the k that we are used to seeing. The computation is as follows:
24 (for 24K) x 0.417= 10 (for 10k),
24k x 0.583 =14k, a common stamp would be 583 or 585
24k x 0.750 = 18k, a common stamp would be 750
24k x 0.917 = 22k, a common stamp would be 917 or 918
24k x 0.999 = 24k a common stamp would be 999
Rarely do you see a number stamp for 10k since 10k gold is not as common in other countries.
Conversly you can also easily calculate the percentage of gold in your jewelry by using the karat:
10k / 24k = 0.417 x 100 = 41.7% gold in 10k,
14k / 24k = 0.583 x 100 = 58.3% gold in 14k
18k / 24k = 0.750 x 100 = 75% gold in 18k
22k / 24k = 0.917 x 100 = 91.7 % gold in 22k
24k / 24k = 1 x 100 = 100% gold in 24k
