22K gold is not that pure as all that
91.6%
The Karet weight of a piece of gold states how much of the piece is actual gold and not silver or copper. A piece that is 22k means that it is 91. 6% pure gold.
Pure gold is 24 karats (24K). 22K gold is almost, but not quite, pure. Some expensive jewelry, especially outside of the US, is composed of 22K gold. Additionally, American Gold Eagle bullion coins and South African Gold Krugerrands are 22K gold composition. Pure gold is .999 fine, while 22K gold is .9167 fine. That means it's 91.67% gold content by weight. You can determine the decimal fineness (as in .9167) by dividing the item's actual karatge by 24. ex. 22 / 24 = .9167 (rounded up)
Karat (K) is the number of parts, by weight, of gold. The higher the percentage of pure gold, the higher the karat. For e.g., 14 karat gold is 58% gold, 18 karat gold is 75% gold, 22k gold is 91.67% gold and 24k gold is pure.
