Gold purity (important if your selling gold):
Indicates the percentage of gold in units of carats of pure gold when set to 24 carats [One carat is equal to 4.1666%]
This pure form of gold is soft and supple it is not mixed with other metals. Other alloy metal that is sometimes mixed with gold include, copper, silver, zinc and nickel. The purity mark in fact marks the percentage of gold in the mixture. The amount of gold used is characterized by a number, a lower carat gold level means it is lower in relation to other metals used. Also effecting the gold price is purified gold which is higher and more expensive than gold per unit weight.
For example,
24 gold contains 999.9 milliseconds to almost 100% gold.
22 contains 916 milliseconds 90% gold.
21 contains roughly 875 milliseconds to 87% gold.
18 contains 750 milliseconds to about 75% gold.
14 contains 585 milliseconds to about 58% gold.
9 carats – contains 375 milliseconds 37% gold.
Golden color:
Three shades; yellow gold, white gold and red gold.
