This is just the jewellers mark, it doesn't have any affect on the value of the gold. The numbers which have meaning and affect the value are: - 333 (8 carat / 33.3% gold content) - 375 (9 carat / 3.75% gold content) - 417 (10 carat / 4.17% gold content) - 585 (14 carat / 5.85% gold content) - 620 (14.8 carat / 62% gold content) - 750 (18 carat / 75% gold content) - 800 (19.2 carat / 80% gold content) - 875 (21 carat / 87.5% gold content) - 915 (22 carat / 91.5% gold content) - 990 (24 carat / 99% gold content) - 999 (24 carat / 99.9% gold content) The most common gold content used in modern jewellery is 3.75% (9 carat).
The difference between 10 carat gold and 18 carat gold is the purity of the gold content. 10 carat gold is made up of 41.7% gold, while 18 carat gold contains 75% gold. This means that 18 carat gold is more valuable and pure compared to 10 carat gold, which has a lower gold content.
The gold content of 10 karat gold is 41.7% gold and the gold content of 24 karat gold is 100%.

After all of the math is done the 1901 half eagle gold coin is about 21 carat gold. They consist of 90% gold and 10% copper.
The specific gravity of 22 carat gold is around 17.7 to 17.8. This means that a 22 carat gold coin will be approximately 17.7 to 17.8 times denser than an equal volume of water.
25 carat gold is not a standard purity level for gold. Typically, gold is measured in carats up to 24, with 24 carat gold being the purest form at 99.9% gold content. Therefore, 25 carat gold does not exist in traditional gold purity standards.
The main difference between 9 carat and 10 carat gold is their gold content. 9 carat gold contains 37.5% pure gold (9 parts out of 24), while 10 carat gold contains 41.7% pure gold (10 parts out of 24). This means that 10 carat gold is slightly higher in gold content and therefore considered slightly more valuable.
Yes 9-carat gold has a relatively low gold content which means it is less soft than pure gold (24-carat) and therefore more durable. 9-carat gold jewellery is very good for everyday use.
If the bracelet is 15g gold and 5g silver, then the gold content is 15/20 or 75%. Pure gold is 24 carat, so 75% is 18 carat.
