Perhaps one of the most important facts you should take note of is that while an 18K alloy is considered gold, this is not always the case with a 9K alloy,depending on the countryit is sold in. For example, in the United States,9-karat jewelry cannot be sold as gold. In order for an alloy to be considered gold in the U.S., it has to have a purity l...
The difference in purity between 9K and 18K gold also leads to a difference in price. Since 9-karat jewelry contains less gold, it is cheaper per gram. 18K gold is significantly more expensive, as it contains twice as much pure gold as a 9K alloy, percentage-wise.
Gold is alloyed with other metals because it is very soft. You can expect lower-karat alloys to be harder than higher-karat ones because of the difference in their gold content. As a low-purity gold alloy, 9K gold is harder than 18K gold. This means that a piece made of 18K gold will be relatively easier to scratch, and its parts will bend more eas...
Alloys with a higher gold content will have a color that is more saturated and yellow. In contrast, lower-karat alloys will look paler in comparison. Compared with 9K pieces, 18K jewelry tends to have a richer color. So, if you are looking for a ring or bracelet that looks more like pure gold, 18 karats is the way to go. 9K jewelry is a recommended...

Used to define the purity of gold in jewelry, 9k refers to the amount of pure gold in a particular piece. Because gold is such a soft metal, it must often be mixed with an alloy to make it more durable. 9k gold is 37.5% gold and 62.5% alloy.
