how many karats indicate pure gold?

Answer 1

24 karat gold is, by definition, pure gold. Pure gold is very soft and would quickly wear, dent and bend in normal usage so it is mixed with another metal to improve its wear resistance. The other metal is often silver, sometimes copper (red gold) and in such alloys the maximum fineness is 22 karat, i.e 22 parts gold and 2 parts other metal.

Answer 2

24 karats is pure gold. Most gold, however, is sold in 10K, 14K or 18K as oppossed to pure 24K. There are a couple reasons. The obvious reason is cost. 10K is the cheapest naturally as it contains the smallest percentage of gold. 14K is more than half gold (12K would be 50% gold and 50% other elements) and is a bit more expensive with 18 karat because the most expensive mixture.
The second reason is because of strength. Gold is a pretty soft element and would not make very good charms and gold chains so jewelers must mix it with something that is stronger and harder. GOOD gold on a good chain is gold that is mixed with other pure strong elements. You can have a crappy 14K gold chain that is less expensive than a 10K gold chain becaus the 14K chain might be mixed with a bunch of CRAPPY metals while the 10K chain is mixed with silver and other more expensive elements that make a high quality piece of jewelry. That is what some of us might call good gold. Its not just the gold but the other half of the elements that the gold is mixed with
Hope this helps. Sorry for LONG post

Answer 3

24 karat gold is considered pure gold. It is not usually used in jewelry because it is too soft and breaks easily.
18 karat gold was the old standard for jewelry in the 40s and 50s to be considered good jewelry. 10 karat gold was considered junk jewelry.
Then the karat gold content went to 14 karat gold and that has been the "good jewelry" (precious) standard until recently when, since the price of precious metals, including gold have skyrocketed, we've been seeing 10 karat gold considered precious jewelry. 12 karat gold was considered semi-precious in the 50s and 60s.

Answer 6

24K gold is pure gold.

18K gold contains 18 parts gold and 6 parts of another metal(s), making it 75% gold.

14K gold contains 14 parts gold and 10 parts of another metal(s), making it 58.3% gold.

12K gold contains 12 parts gold and 12 parts of another metal(s), making it 50% gold.

10K gold contains 10 parts gold and 14 parts another metal(s), making it 41.7% gold. 10K gold is the minimum karat designation that can still be called gold in the US.

Gold won't tarnish, rust, or corrode, and though it's very strong, it is also the most malleable of all metals.

Pure gold is too soft to withstand the stresses of every-day wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability.

Karatage, noted by a number followed by "k" indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24k gold 100% gold.

Answer 7

Karats have nothing to do with gold. Karats are the size of the diamond.
