The number badges on precious gold jewelry are a little confusion for lots of people. We usually used to see a carat or silver mark like this: 10K, 14K, 18K, Sterling, etc. The numbers mean the same thing.
The 14k number is technically 583 but most manufacturers adopted the European road and makes 14k gold a little bit over 14k, so the brand is 585 in most 14k jewelry. 18K is marked 750. If the mark is valid and there is a marking label also in jewelry, the number means that these items are 18k gold.
Here's where the numbers come from. Pure gold is called 24 carat. For 18k gold there are 18 parts pure gold mixed with other metals to make the metal suitable for use in jewelry. 24k is too soft alone to stand up or to keep stones good. 18 parts pure gold divided by 24 or 18/24 equal to 750. This is where the number comes from. Jewelry is 75% pure gold, 750 parts gold with 250 parts other metals of "1000" parts. It is easier to think of it as a percentage that is pure gold in the recipe.
Sterling silver is labeled 925. Sterling is 92.5% pure silver and the rest is other metal, usually copper.
What does it mean if the ring marked 14K PR? 14K simply means that it is 14K (Karat) gold and because of K it means that it would have been made in either Southeast Asia or the United States. The PR marks are just Maker or Store ID or even a design mark, and have no relevance to the value.
The basic decimal formula for elaborating the quality of the gold content is quite simple, since they are all measured in & # 39; Parts per thousand. & # 39; This means that 9kt gold is calculated as follows: 9 (for 9ct) is divided by pure gold (24) and then multiplied by 1000 (for pure gold as a decimal number). ie: 9/24 * 1000 = 375 The 375 is the decimal quality for 9kt gold and is sometimes shown with one decimal in the front - .375
The old Victorian standard of 15kt gold is calculated the same way - 15/24 * 1000 = 625 (Not really the numbers you have on your jewelry. Decimal and work back, ie: 375/1000 * 24 = 9
In your case we can use 698/1000 * 24 = almost 17ct
I have a platinum engagement ring and found a wedding ring that I really like but the band is made of palladium. Is it safe to carry these two metals together without harming the other?
It will carry the softer metal over time but it may take many years. My grandmother's wedding ring has ever worn the band in her engagement ring but it took over 20 years to do.
Platinum and Palladium and pretty good together but I would get the advice of your local friendly jeweler and make them control both rings. Sometimes platinum can be lower to make it harder - so it has checked.
