14k Gold

What is gold?
With other numbers of metals or alloys such as copper or iron pyrite, copying gold color is easy. They will look just as the gold as the real 14k gold. So why pick 14k gold? The answer is easy. Gold does not change in color, rust or corrode or fade. Gold survives time. Also gold can be shaped to any size or shapes.
However with gold’s flexibility has a drawback. Due to its flexible nature, gold’s strength in minerals or harness is near the bottom of the chart. Because of these weaknesses, gold is mixed with one or more additional metals to make it strong. We call this alloy; they are usually copper, silver, nickel. These alloys not only strengthen the gold, but determine the color of the gold. For example, yellow gold will contain copper, and white gold will have nickel, zinc and copper is mixed in. With these concepts, gold can come in many color such as pink gold or also know as rose gold, or purple gold etc.

What does karat means in 14k?
In mineral community, precious metals measured in ounces. But this ounce system is not the system of 16 ounces to a pound which we are familiar with. Gold is instead measure what ancient troy standard. This standard is also used in pharmacists and medical profession today. Here is an example of weight system.

1 troy ounce = 480 grains
= 20 pennyweights
= 1.097 avoirdupois ounces
= 31.103 grams

1 troy pound= 12 troy ounces
= 5760 grains
= 240 pennyweights
= 13.164 avoirdupois ounces
= 0.82275 avoirdupois pounds
= 373.236 grams

Karat in most in English speaking countries spells in “carat” but in U.S. carat is used to measure gem stone’s weight such as 1 carat diamond. The word carat is from ancient time when it was used from carob plant which was used to measure weight of gemstones. Carob plant’s seed was used for this process. One carob seed weighted about 200 milligrams.
Now going back to gold, purity of gold is measure from 1 to 24. 24 karat (24K) is purest form of the metal. So when you hear 18k gold, it means 18/24 karat which is 75% of gold and 25% alloy. More alloy, or lower karat in gold, gold becomes much more strong.
