 | | Don’t confuse this 'carat' with the term 'karat,' which is the measure to determine the purity of gold. | | | Carat is the easiest of the 4Cs to determine but remember two diamonds of equal carat weight can have very different values depending on the quality of the cut, color, clarity. | | | The weight or size of a diamond is measured in CARATS. |

| | Carat weight |
| | Another common source of confusion: The karats used to measure the purity of gold have nothing to do with the carats used to measure the weight of a diamond. | | | Since most diamonds sold in the jewelry industry weigh less than 1 carat, the carat is usually subdivided into "points." There are 100 points in 1 carat, so that a diamond weighing 3/4 carat would be a "75 point diamond." In summary: | | | This argument is similar to that of cereal boxes or potato chips, where "contents are sold by weight, not volume." Also, don't confuse the carats of a diamond with the carats of a different stone. |

| | Carat Weight |
| | Carat is also often confused with size even though it is actually a measure of weight. | | | Clean emeralds over three carats with good quality get the best prices of the market, sometimes superior of diamonds. | | | The term "carat" is universally accepted for most gemstones as a measure of weight. |

| | Carat - Wikipedia |
| | The carat (spelt karat in the U.S., to distinguish it from the unit of mass above) is also a measure of the purity of precious metals such as gold. | | | However, in 1907 the metric carat of 200 milligrams was adopted, which is now universally used today. | | | In the past, different countries each had their own carat. |

| | Carat (purity) - Wikipedia, the free encyclopedia |
| | The carat system is increasingly being complemented or superseded by the millesimal fineness system in which the purity of precious metals is denoted by parts per thousand of pure metal in the alloy. | | | Therefore 24-carat gold is pure gold (99.99%), 12-carat gold is 50% purity, etc. In the United States and Canada, the spelling karat is usually used for the measure of purity, while carat refers to the measure of mass. | | | Carat is a measure of the purity of gold and platinum alloys. |

| | Gold purity, gold carat, gold alloys, ring stamps and manufacture, including choosing 9 carat or 18 carat gold |
| | A Carat is the measurement of the purity of gold, the number of gold parts per 24. | | | Although 18 carat gold is only fractionally softer than 9 carat gold, when it is annealed in the ring making process 18 carat gold is only fractionally harder than 9 carat gold. | | | When choosing between 9 carat or 18 carat gold it probably best to say that 18 carat gold will have a brighter luster and shine after the passing of time than 9 carat gold. |

| | Audreys Claddagh Irish Jewelry Guarantee |
| | Gold is the ultimate precious metal and its purity is always measured in carats, the purest being 24 carat. | | | This combination can be understood as a fraction; 10 carat is measured 10/24 or 416 parts gold per 1000, 14 carat is 14/24 or 583 parts of gold per 1000, and 18 carat is 750 parts gold per 1000 parts. | | | Gold of this purity, however, is impractical to wear as jewelry since it is very soft, can damage easy, and cannot maintain the delicate designs of our fine Irish jewelry. |

| | Ask for a gram more in 22-carat jewellery |
| | If 24 carat is 100 per cent purity (it is called 999-99.99 per cent, since practically, gold cannot be retrieved from ore in its 100 per cent purity), then each caratage is 4.17 per cent. | | | It is, therefore, better to melt the metal to one caratage higher than the desired one to 19 carats if the piece is to be made in 18 carats and to 23 if the piece is to be made in 22 carats. | | | Also, even as the differential between 24 and 22 carat gold is ideally proportionate, which is reflected in the quotations for publications, it is far from it at the jewellers' shops. |

| | Minesite Story |
| | In the States the lowest gold purity that is acceptable is 12 carat which is half gold and half alloy, but the scale really starts at 14 carat and works up to 22 carat. | | | To call this alloy 9 carat gold is to perpetuate a confidence trick and it does not sit easily for the WGC to pontificate about the investment qualities of pure gold while allowing this farce to continue. | | | A similar ring made out of 9 carat gold is, therefore, worth no more than £16.68, but as already pointed out the gold percentage of the alloy is so low that it has virtually no real value. |

| | It is an extension of the older carat (karat in North American spelling) system of denoting the purity of gold by fractions of 24, such as "18 carat" for an alloy with 75% (18 parts per 24) pure gold. | | | The millesimal fineness is usually rounded to a three figure number, particularly where used as a hallmark, and the fineness may vary slightly from the traditional versions of purity. | | | Millesimal fineness is a system of denoting the purity of platinum, gold and silver alloys by parts per thousand of pure metal in the alloy. |
