A unit of fineness or concentration of gold equalling 1/24 part of gold in an alloy
Karat or karatage or caratage is an expression of the measurement of gold purity (since gold is in fact a mixture of gold and other metals). Pure gold is 24-Karat (24K), 18-Karat gold is 75% pure, etc
A unit of measure for the fineness of gold, equal to one twenty-fourth part of pure gold in an alloy Pure gold is 24 karat
variation of the word carat now used to describe the purity of gold, being 1/24th part by weigh of pure gold i e 24 karats being pure gold e g 14 karat is 14 parts pure gold to 10 parts of other metals
A measure of fineness; 24 karat is fine gold One karat equals 1/24 ( 0417%), so that 14 karats is 14/24 fine gold and the balance (10/24) alloy If the gold content of an alloy is less than 10/24 the object cannot be represented as karat gold
{i} unit for measuring the weight of precious stones (equal to 200 milligrams); unit for measuring the quality of gold (also carat)
The method by which fineness of gold is expressed Pure unalloyed gold is 24 karat As an alloy metal is added (usually copper), the karat value declines: 22K, 20K, 18K, and so on The lowest grade of gold to carry a karat mark in the United States is 10K, or, in Great Britain, 9K Most gold coins are 20K or 21K Jewelry is commonly 9K to 18K The word karat derives from the carob bean, used as a measure of weight in the ancient world When spelled "carat", it refers to the weight of a precious gem and has nothing to do with the fineness of a metal in the United States
The measure of purity of gold-24K gold is 100% pure, 18K gold is 75% pure, 14K gold is 58 5% pure
The measure used to express the purity of gold, 24 karat being the highest or purest An alloy of one-half pure gold and one-half other metal would be expressed 12 karat
Unit of fineness, scaled from one to 24 24-karat gold (or pure gold) has at least 999 parts pure gold per thousand; 18-karat has 750, etc
Karat (abbreviated Kt) is a measure of the fineness of gold 24 karat gold is pure gold 18 karat gold is 18/24 gold (about 75% gold - three quarters gold) 14 karat gold is 14/24 gold (about 58% gold - a little over half gold) 12 karat gold is exactly half gold 10 karat gold is 10/24 gold (only about 43 5% gold - less than half gold)
