The purity of gold is measured in carats.
Carats are also used to measure the weight of precious stones, including diamonds.
These are two quite different measurements, and two quite different uses of the same word.
Carats is used especially for gold (as an equivalent of gold percentage).
CT means carats. The purity of gold is measured in carats, 24 ct indicating 100% pure gold.
Diamond purity isn't rated in carats. Carats are a designation of mass/ weight. Diamond purity is a separate rating.
Gold is measured in carats. It it made up of 24 carats (parts) altogether. If the jewelery is 9 parts gold and 15 parts other metals, it is 9 carat gold. If it is 18 parts gold and 6 parts other, it is 18 carat gold. The more carats it is, the more valuable it is.
9CT means 9 carats, which indicates 9/24 or 37.5% purity of the gold, alloyed with other cheaper metals. Gold is normally sold in 9ct, 14ct, 18ct and 22ct.

The purity of gold is measured in "Carats"The size of diamonds is measured in "Carats", use of the measurefor other gems is common but incorrect (just marketing).
The weight of a diamond is measured in carats (1 carat = 0.2 grams; it is a measure of weight). The purity of a gold setting is measured in karats (24 karat = pure gold, 18 karat = 75% gold)
Diamond purity isn't rated in carats. Carats are a designation of mass/ weight. Diamond purity is a separate rating.
Carat is an indicator of weight; karat is an indicator of purity. Diamonds are measured in carats; gold is measured in karats. So, how big is a karat of gold? It can be as small as a molecule. There is no limit to how large a karat (purity) of gold can be.

A carat is actually a standard unit of measure that defines the weight of a diamond. One carat is equivalent to 200 milligrams. Carat sizes are also expressed as “points”, with a one carat diamond equaling 100 points, a one-half carat diamond being 50 points, a three-quarter carat diamond being 75 points, and so on.
A carat is a unit of weight for precious stones, which is equivalent to 200 milligrams. In terms of precious stones, they are described in ¼ increments.In terms of gold, Karat (K) is the number of parts, by weight, of gold. The higher the percentage of pure gold, the higher the karat. For e.g., 14 karat gold is 58% gold, 18 karat gold is 75% gold and 24k gold is pure. Both gold and diamonds/emeralds/rubies/sapphires and some semi precious stones are measured in carats.
