used in jewelry to denote the fineness of a gold alloy. Pure gold is 24-karat and too soft for jewelry use.

The fineness of gold, equal to one part of 24 in gold alloys. 14Kt gold is actually just 58.5% fine gold, and the rest various alloys and combinations of metals. 18Kt is 3/4 fine gold or 75%, and the richer color is from this increase in fine gold. White gold is a trick, the alloys fool your eye into seeing white, along with the fact that most manufacturers will also rhodium plate the white areas to enhance their white and brightness

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.

A measure of fineness equal to 1/24 part pure gold in an alloy. Fine (pure) gold is 24k. If an article is made of 18k gold it is 18 parts pure gold and 6 parts other metal.

A unit of measure of gold content. Pure gold is 24 karat and one karat is equal to1/24 part pure gold in an alloy. (14kt. gold is 14 parts gold and 8 parts other metal.)

Karat (K) is a measure of the fineness of gold. 24 karat gold is 100% gold. 18 karat is 75% gold. 14 karat is 58.3% gold. 10 karat is 41.7% gold. Gold is a soft metal and is often mixed with another metal to give it strength. See "gold" above.

Measure of the quality of gold. 24 karat (24k) is pure gold. Anything less than 24k is an allow. For instance, 12k is 50% gold. Food of choice for poor-spelling bunnies.

A term that describes the amount of pure gold in an alloy. Pure gold is 24 karats (24K), 18 karat (18K) gold is 18 parts gold and 6 parts other metal, resulting in 75% gold. 14 karat (14K) gold contains 14 parts gold and 10 parts other metal, resulting in 58.3% gold. 10 karat (10K) gold contains 10 parts gold and 14 parts other metal, resulting in 41.7% gold. 10k gold is the minimum karat designation that can still legally be termed gold in the United States.

is the amount of gold in an item.

The measure of purity of gold-24K gold is 100% pure, 18K gold is 75% pure, 14K gold is 58.5% pure.

Karat is a measure of the goldâ€™s purity. Most gold jewelry is actually made from a gold alloy containing gold and another metal or metals. (See 10 karat, 12 karat, 14 karat, 18 karat and 24 karat.)

The karat mark tells you what proportion of gold is mixed with other metals. Fourteen karat (14K) gold contains 14 parts of gold, mixed in throughout with 10 parts base metals.

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.

A unit of measure for the purity of gold, indicated with the symbol 'k' or 'kt.' Pure gold is 24 karat (24k). But pure gold is usually too soft to be used in jewelry, so most pieces are a mixture of gold and other metals. The higher the karat, the more gold. A 14k jewelry piece is about 58% gold, while an 18k piece is about 75% gold (and is therefore more expensive). The fineness of gold is measured on a scale of 1,000 outside the U.S. An 18k gold piece is labeled 750, for instance.

Indicates the amount of pure gold present in a metal. 18K yellow gold consists of 75% gold and 25% other metals; these are usually copper and silver. 14K yellow gold consists of 58% gold and 42% other metals.

index of gold purity ( 1kt=4.167%): 24 karat gold â€” 100% gold ( very soft) 18kt. â€” 75% ( not tarnish and has a deeper color) 14kt. â€” 58.33% 12kt. â€” 50% Gold 10kt. â€” 41.6% Gold Less than 10kt. in the US or less than 9kt. in the UK cannot be called gold.

a measurement of the purity of gold

a measure of the portion of pure gold in an alloy

a unit of measurement for the purity of gold

a unit of purity of gold or gold alloys

indicates purity of deposit. 24kt consists of 100% gold; 18kt, 75% gold; and 14kt 58.3% gold.

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.

24 karat is 100% pure gold, 18 karat is 75% gold with 25% other precious metals added to modify color and strengthen durability. Each karat equals 4.167% gold.

A term used to denote gold purity. The designation for fine gold is 24K therefore 9K is 375 or 37.5% pure.

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

The proportion of pure gold in an alloy. Pure or fine gold is 24 karat; 10-karat gold is 10/24 pure, or 10 parts of pure gold by weight mixed with 14 parts of other metals. Not to be confused with carat

the percentage of gold content. For instance pure gold is 24 karat or 24 out of 24 parts are gold, thus 100%, 18karat is 75% gold or 18 parts gold out of 24, 14karat is 58.5 % gold or 14 parts gold and 10 parts alloys.

A measure of the proportion of gold in an alloy. Expressed as the number of parts of gold in 24 parts of the alloy. 18 Karat for example would be 18 parts of gold (of 24 totalparts) and 6 parts of other metals.

Is a measure of the purity of gold. Twenty-four karat (24K) is considered as pure gold. See Fineness.

Karat (abbreviated Kt.) is the measurement of gold used to note the purity and fineness of the metal. Karat indicates the purity of the gold substrate.

Measurement of gold's purity. Pure gold is 24 karats, but 24K gold is too soft to securely hold a stone. So gold is alloyed with other metals such as silver, copper and zinc to make it sturdier. Typical measurements for alloyed gold are 18K (75% gold), 14K (58.3% gold) and 10K (41.6% gold). In the United States, metal that is less than 10K cannot legally be sold as gold. However, a lot of vintage jewellery falls in the 9K to 10K range.

The measurement of the purity of gold. 24 karat gold is pure gold, while 12 karat gold is 50% gold and 50% alloy.

a measure of the purity of a precious metal. Pure gold is 24 karat.

Used to state how much pure gold is found in a item. 24K is pure gold, 18K is 18 parts gold and 6 parts other metals, 14K is 14 parts pure gold and 10 parts other metals etc.

Abbreviated with the letter â€œKâ€, karat refers to the purity of gold, which is often alloyed with silver, nickel, copper or other metals to improve its workability and make the soft metal more durable. This is what the following marks mean: 24K = 100% pure gold 18K = 18 parts gold and 6 parts alloyed metal(s) or 75% pure gold 14K = 14 parts gold and 10 parts alloyed metal(s) or 58.5% pure gold

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.

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 unit of measure for gold fineness, on a 24-point scale. Pure 24 karat gold is too soft for jewellery, so it is blended with other metals for strength and color. See also gold. 18 karat gold is 75% gold. 14 karat gold is 58.5% gold. 10 karat gold is 41.67% gold. Stamped 18K or 750, 14K or 585, or 10K. Abbreviated K or Kt. Do not confuse with carat (q.v.).

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

The fineness of gold (also see "carat," used for gemstones). 24K is pure gold. 18K is 18 parts gold, 6 parts other metals. 14K is 14 parts gold, 10 parts other metals. 12K is 12 parts gold, 12 parts other metals. 10K is 10 parts gold, 14 parts other metals.

A number used to describe how many of the 24 parts of pure gold are alloy. Fourteen karat gold has 14 of 24 parts being pure gold, and the remaining 10 parts being alloys.

(with a "k") A measure of gold fineness or purity. Pure gold is considered to be 24 karat. For this reason, the actual gold content of any object is the percentage relationship of its purity to 24. For example, 18 karat gold is 18kt/24kt or 75% pure gold or 750 fine.

The percentage of fine gold in an object. 24k gold is pure, but pure gold is too soft to be used for jewelry so other metals are added. All gold is measured in terms of 24 parts. For example, if an item is listed as 14k, it is comprised of 14 parts of gold and 10 parts of some other metal.

Unit of measurement that indicates the quantity (or parts) of fine gold in a piece of jewelry. This karatage is always based on pure 24-karat gold. For example, 18-karat gold contains eighteen parts fine gold and six parts other metal alloys.

A variation of the word "carat", (used to describe the weight of a gemstone), "karat", with a "k" is used to describe the purity of gold. Gold is often alloyed with silver, copper, and/or other metals to improve its strength and durability. Products made from gold are marked to show how much actual gold is contained in the product. Items marked 24K are 100% pure gold. Items marked 18K or 750 have 750 parts gold out of 1000, or 75% pure gold. Items marked 14K or 585 have 585 parts out of 1000, or 58.5% pure gold. Much of the jewelry manufactured before the 20th century do not have these marks and must be tested to determine purity.

measurement of purity used in showing the fineness of gold, scaled 1 to 24. One karat is 1/24 pure gold.

A unit of measure for the purity of gold, equal to 1/24 part. Pure gold is 24 karat; gold that is 50 percent pure is 12 karat.

The unit to measure gold purity. 100% gold, for example, is 24 karat, while 75% gold is 18 karat.

A unit of weight to express the quality of a gold alloy, such as 18 karat or 14 karat. Pure gold is 24 karat. The word is spelled karat when applied to precious metals, and carat when applied to weight of gemstones.

Refers to an alloy's gold content; 14 karat describes a content of roughly 60% or greater, while "pure" or 18 karat gold, surprisingly, may have as little as 75% gold content. (Not to be confused with the term, carat; see above.)

An indication of the purity of the metal used, expressed in the number of 1/24th of the pure metal used in the alloy. Metals such as gold are too soft in their pure state use in jewelry, so they are typically made into an alloy with other metals for strength. 24K (equal to 24/24ths) is pure metal. 18K is 18 parts pure metal mixed with 6 parts of other metals. That translates to 18/24=0.750, which is 75% pure, or 750 parts per thousand.

The standard measure of gold purity wherein one karat is 1/24th pure, meaning 24 k gold is pure gold.

the measure of the purity of gold.

A measure, from 1 to 24, used to indicate how much of a piece of jewelry is gold content and how much an alloy.

A unit of fineness for gold jewelry. Twenty-four karat is equal to 100% pure gold; 18 karat contains 75% pure gold; and 10K gold contains 41% pure gold.

A proportional unit used to describe the purity of gold alloys. Based on the number 24, gold alloys can be described by the percentage of gold in a sample; 14 karat, for instance, refers to the fraction 14/24ths, or 58.5% gold. A more scientific description, gaining in popularity and standard in Europe, is to refer to parts per thousand, or .585.
