That's the place the quantity comes from. The jewellery is 75% pure gold, 750 elements gold with 250 elements of different metals from "1000" elements. It’s simpler to consider it as a proportion of pure gold within the recipe.
Sterling silver is marked 925. Sterling is 92.5% pure silver and the remainder is one other metallic, often copper.

Outdated Victorian commonplace 15kt gold is calculated in the identical approach – 15 / 24 * 1000 = 625 (Not all of the numbers you’ve got in your jewellery. Dental gold is 16ct or 666 repeated. However you can even flip this recipe by beginning the decimal and dealing once more, ie: 375/1000 * 24 = 9
In your case we are able to use 698/1000 * 24 = virtually 17ct
