How to Read Jewelry Marks

Numerals of gemstone jewelry are a lot of annoyance for many people. Usually we see a karat or silver mark: 10K, 14K, 18K, Sterling, etc. The numbers are the same.

For the 14 k, the number was technically 583, but most manufacturers accepted the European mode and 14 k gold more than 14 k, which was 585 for most 14 k jewels. The 18K has a 750 mark. If the trademark is valid, and the number of decision makers on the jewelery is 18 k gold.

Here the numbers come from. The pure gold is called 24 carats. 18 silver gold, 18 parts pure gold mixed with other metals, making the metal suitable for jewelery. The 24k is too soft to stand up or keep a good lap. 18 pieces of pure gold divided by 24 or 18/24 are equal to 750. This is where the number comes from. Jewelry is 75% pure gold, 750 gold and 250 parts other metals from the "1000" section. It's easier to think like a percentage of pure gold in the recipe.

The sterling silver is 925. The sterling is 92.5% pure silver and the rest is other metal, usually copper.
What does the ring mean with 14K PR? 14K simply means that 14K (Karat) is gold, and for K it means that it would have been made in Southeast Asia or the United States. PR notations are just the Maker or Store ID or even the design sign and have no relevance to the value.

The basic decimal formulation determining the quality of gold content is quite simple, as each one is measured in thousands of pieces. & # 39; This means that 9 cst gold is calculated as follows: 9 (9 cc) of pure gold (24) divided by 1000 (pure gold per decimal). that is, 9/24 * 1000 = 375 This is 375 decimal degrees for 9ct gold and sometimes before a decimal point – .375

The 15ct gold old Victorian standard is calculated in the same way – 15/24 * 1000 = 625 (Not enough figures for your jewels, decimals and backs, ie: 375/1000 * 24 = 9

In our case I found a platinum engagement ring of 698/1000 * 24 = almost 17%
and found a wedding ring

Grandmother's wedding ring pulled the band of the engagement ring but it lasted for more than 20 years

Platinum and Palladium , and very good together, but advising local friendly jewelers and checking both rings, sometimes Platinum may be a lower grade to make it more difficult – so check
