The "carat" number in gold refers to the percentage of gold in the alloy. Gold rings are seldom pure gold because the metal is so soft that it scratches and bends easily. Most gold rings are 18 carat gold, refering to a specific percengage of gold and other metals that have been melted together to give it the color of gold while giving it additional strength. Once you get down to an alloy of 9 carat, there isn't really much gold in the metal. At that point, it's only 37.5% gold. But if you are planning on creating a larger ring, you can add more gold to it to bring the total amount of gold up to 75% of the total metal in the ring. For example, you could make the ring thicker.
Well the difference is that 9K gold is not consider gold in the USA is usually made in england,18k gold is 75.0% pure gold 9k gold is less than 10k gold witch is 41.7% pure gold that's why in the USA is not consider gold.

Weigh the ring. If it is 24 carat gold then the ring is pure gold and all of the weight is gold If it is 22 carat gold then the ring is 22/24 gold and the weight of gold will be reduced by 1/12 Any other degree of pureness can be calculated similarly.... 18 carat gold is 75% gold, 12 carat is 50% gold and so on.
nine 24th of the weight. Pure gold is 24 carat. The dilution through the addition of base metals makes the gold more hard wearing but reduces the cost.
