What does karats mean is gold?
It is used to measure the purity of gold alloys. One karat (or carat) is equal to 1/24 purity by mass.
- 24 carat (millesimal fineness 99.9% or higher)purity
- 22 carat (millesimal fineness 91.6%)purity
- 21 carat (millesimal fineness 87.5%)purity
- 20 carat (millesimal fineness 83.3%)purity
- 18 carat (millesimal fineness 75.0%)purity
- 15 carat (millesimal fineness 62.5%)purity
- 14 carat (millesimal fineness 58.5%)purity
- 10 carat (millesimal fineness 41.7%)purity
- 9 carat (millesimal fineness 37.5%)purity
- 8 carat (millesimal fineness 33.3%)purity
- 1 carat (millesimal fineness 04.2%)purity
Gold purity is measured in karats based on 24 karats being pure gold. 18k means the gold is 18 out of 24 karats pure: 18 parts gold to 6 parts alloy. 9k means the gold is of low purity, only 9 parts gold to 15 parts alloy. The letter k after a number normally means "thousand" when your talking about gold, silver, etc. It is normally used in games like runescape etc.
Carats and Karats are different. Carat weight is used to measure gemstones. 1 carat is 200 milligrams weight. Karat is used to measure how pure gold is. 100% pure gold is 24 karats. So if a piece of jewelry contains 50% gold then it is 12 karats. (Carrots are root vegetables high in vitamins and glucose)
There's actually no such thing as 9 ct gold, since "ct" stands for diamond carats. I assume you are referring to gold karats, "kt". Gold is typically mixed with other alloys due to its extreme softness. The number of gold karats expresses the purity of the gold. In the case of 9 kt gold, the gold is 37.5% pure.
The 925 or .925 is the marking that indicates your jewelry is at least 92.5% sterling silver. If it were to say 10k or .925/18k it would indicate that the metal is either 10 karats gold, or sterling silver with 18 karats plated gold.. The H is the manufacturer's signature to ensure the customer can trust where the markings and jewelry has come from.
is this a real question or are you testing me? anyway, pure gold is very malleable, which is why they usually put some degree of silver into it to make it stiff. pure gold is very easy to break and bend, so it is not usually used in jewellery. pure gold is said to have 24 karats, while half and half silver and gold is about 12 karats. once the mix hits 3 karats, it…
