A unit of weight denoting the size of both uncut and cut gemstones. There should be 100 points to a carat (ct.). The newcomer to diamond buying should be careful not to become so influenced by carat size that he or she ignores or fails to recognize the importance of such points as clarity, color, and cut.
A carat (ct.) is a standard measure of weight used for gemstones. One carat weighs 0.2 gram (1/5 of a gram or 0.0007 ounce). A hundredth of a carat is called a point. The carat unit was introduced in 1907.
Carat, a variant of the word karat, is a unit of measurement of a diamond's weight equivalent to 200 mg. Carat Weight represents one of the Four C's used to determine a diamond's quality and ultimate value.
The purity of gold is described by its finest or carat as parts of 24. Thus 18 carat (out of 24) is 75 percent gold. Gold is often alloyed with other metals to increase its hardness or change its color.
A value out of 24 used to describe the purity of precious metal. For example, 24 carat gold is pure gold, 22 carat is 91.67% pure and 18 carat is 75% gold and 25% of some other metal such as silver or copper.
A unit measurement of weight used for precious gemstones. 1 Carat = 0.2 Gram (The term carat is derived from the ancient carob seed from the locust tree, used as a medium of exchange on early pan-balances. In the early 1900's the metric carat was established.)
One of the Four C's, carat refers to t he standard unit of weight used for gemstones. One carat equals .200 grams (or 200 milligrams). Weights are given to the nearest 1/100th of a carat, an amount which is called a "point." For example, a .50 carat gemstone might also be called one-half carat or a 50-point stone.
One of the "4 C's," carat is the term used to define the measure of weight of a diamond. One carat is the equivalent of 200 milligrams. One carat can also be divided into 100 "points." A .75-carat diamond is the same as a 75-point or ¾-carat diamond. Carat Total Weight: The total diamond carat weight of all the stones in a piece of jewelry.
Introduced in 1907, a carat is a unit of weight or measurement for diamonds or gemstones equal to 0.2 gram (1/5 of a gram or 0.0007 ounce). Carat weights are expressed in fractions or decimals. One hundred "points" equal one carat. Sometimes incorrectly spelled "karat." In the U.S., however, karat strictly refers to the fineness of pure gold or gold alloys.
Weight measurement used in reference to gemstones in regard to their evaluation. A carat is .2 grams (or 200 milligrams), and this weight is used worldwide, even in the U.S. where the metric system isn't used. A point is the weight used only in reference to very small, precious gemstones, and represents 1/100th of a carat. The abbreviation for carat is Ct. and for point is Pt. The term carat in regard to gemstones should not be confused with the term carat in regard to gold. By gold, it refers to the content of gold a gold ornament contains. Because of the confusion, the term carat in regard to gold has been changed to karat.

A measure of weight used for gemstones. Not to be confused with â€œkaratâ€, which is a measure of gold alloy purity. Often abbreviated as â€œct.â€ one carat is equal to 200 milligrams (one fifth of a gram). Gemstones are measured to the nearest hundredth carat (known as a â€œpointâ€™). For example, a .25 carat stone would be said to have twenty five points. A carat is one of the 4 Cs of diamond grading. The others being Clarity, Cut, and Color.
A unit of weight for diamonds, pearls and other gemstones. 1 carat = 200mg or a unit used to measure the purity of gold ie 1 carat = 1 out of every 24 parts is gold 2 carat = 2 out of every 24 parts is gold 24 carat gold is pure gold
This has nothing to do with the previous definition. In this connotation it denotes the quality of gold, or the amount of gold in an alloy. A carat is one 24th part of a whole, therefore: 24 carat gold = 24/23ths = 100% pure gold. 18 carat gold = 18/24ths = 75% pure gold. 14 carat gold = 14/24ths = 58.5% gold.
The standard unit of weight for diamonds. Five carats equal one gram. Abbreviated as ct. or cttw. Cttw. stands for "carat total weight," or the sum weight of all diamonds in a piece of jewellery. Do not confuse with karat (q.v.).
Abbreviated "ct." and spelled with a "c" for gemstones ("k" is used for karat in gold). One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. A hundredth of a carat is also called a point. Thus a .10 carat stone can be called either 10 points, or 1/10 of a carat. Small stones like .05, and .10ct, are most often referred to by point designations. A one-carat round diamond of average proportions is approximately 6.5 mm in diameter, but this relationship of weight and size is different for each family of stones. (Ruby and sapphire are both heavier than diamond.)

Standard to define the fineness of gold and gold alloy, expressed as a number out of 24 parts, e.g. “14 carat” means 14/24ths gold in the alloy. 24 carat gold is pure gold. Most jewellery uses gold of 14 of 18 carats. For convenience, the fineness of gold may be expressed in thousandths rather than carats: - 24 carats = 1,000 thousandths (1.000), - 18 carats = 750 thousandths (0.750), - 14 carats = 583 thousandths (0.583), - 12 carats = 500 thousandths (0.500).
