Just a pair of straight vertical lines, one on either side of the number. The absolute value of 18k is |18k| . The absolute value of 'x' is |x| .
If gold is real it will be stamped with a fineness number of 1-999 or .1-.999. It can also be stamped with a karat number of 10K, 14K, 18K, 22K or 24K.
Probably that it was # 766 of an 18k Design.
18k refers to the gold content (18k = 75% gold) with the rest being silver or other metals 159 refers to the purity of the silver
these are the proper hallmarks 24 Karat Gold - 24K or 999 22 Karat Gold - 22K or 917 21 Karat Gold - 21K or 875 18 Karat Gold - 18K or 750 14 Karat Gold - 14K or 585 10 Karat Gold - 10K or 417 9 Karat Gold - 9K or 375 14 Karat Gold filled - 14K GF or 14K/20 Sterling Silver - 925 Pure Silver - 999 the ratio is A/24=B for example 10/24=0.417 therefor 10K=417
No 18k shines more because its more pure gold
The color of gold (yellow, white, rose) is determined by the metal alloy mixed with the gold. Both 18K and 14K gold can come in various colors depending on the metal alloy used. The difference between 18K and 14K is the purity of the gold, with 18K being 75% pure gold and 14K being 58.3% pure gold.
14k gold is 14 parts gold mixed with 10 parts other (cheaper) metal (58.3 % gold) 18k gold is 18 parts gold mixed with 6 parts other metal (75% gold) So 18k is more expensive than 14k
The difference in price between 14k and 10k gold is based on the higher purity of 14k gold, which contains more gold than 10k. Similarly, the price difference between 14k and 18k gold is due to the higher gold content in 18k gold, making it more valuable.
Gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
14K, 18K, 9ct are the most popular you will also see 585 for 14k gold and 750 for 18k.
14k-18K refers to the purity of gold in the jewelry piece. 14k gold is 58.3% pure gold, while 18K gold is 75% pure gold. The "KG" likely refers to the weight of the gold in the jewelry, measured in kilograms.
14k-18k
For most of the countries, jeweler are required to stamped the jewelry with 9k / 10k / 14k/ 18k / 22K / 24K to show the gold contents! The greater the gold contents, the greater the value!
While 24K is solid gold and 18K gold has other alloys. These alloys are to increase the strength of the material and thus its durability. So if you are looking for jewellery then 18K would be best but if you are looking for investment then you should go for 24k gold.-Kathana jewellers24K is solid goldnapolean
14k to 18k real jewlery is safe
It means that its between 14k and 18k that it has about 60%-70% GOLD in it.
