Gold is the purest of almost all metals and this where the term purity of gold comes from it means the metal is not changed from it's original state in the ground to its state in the shops and stores and no chemicals are added and nothing is changed except for the size and shine. This though is what i have been lead to believe and may not be scientifically correct./

What is the percent gold in 24 caret vs 18 caret gold vs 14 caret?
24K Gold Purity - 100% 24K Gold Purity - 75% 14K Gold Purity - 58.33%
How do you find percent age purity?
Answer: Divide purity units by the number of units that represents 100% purity, then multiple by 100. The answer will be the percentage purity. For example: If a piece of gold contains 18 units of gold and 100% pure gold is 24 units, then we can calculate the purity of the gold piece as follows: 18/24 = .75 * 100 = 75% purity.
What does 925 mean on a ring?

What's the difference between the different types of gold?
The difference between the different types of gold is in the purity of the gold. The karat weight of gold is measured by a gold's purity, with 24 karat gold being pure gold. Therefore, 22 karat gold would have a purity of 22/24 or 91.7 percent, 18 karat gold would have a purity of 18/24 or 75 percent, 14 karat gold would have a purity of 14/24 or 50 percent and 10 karat gold would have a purity of 10/24 or 41.6 percent. As the purity of gold decreases, the alloy in the jewelry increases. Copper and silver are the most common alloys used when making gold jewelry and white gold is usually made with a nickel alloy. The higher karat weight a gold piece of jewelry has, the more valuable that piece of jewelry will be.
Is gold sold per carat mass?
Gold is sold by its purity (Karat) and its weight The Karat (K) is the purity of the gold: 24K Gold = 1000 = 100% Gold 18K Gold = 750 = 75% Gold 14K Gold = 585 = 58.5% Gold........and so on By knowing the weight of the gold and the purity (Karat) you can determine how much mass is solid 24K gold and determine a price!!
