What do mean by 24 carat gold and 18 carat gold?
24 carat gold is pure gold. The purity of gold is measured as a ratio out of 24. For example; 18 carat gold is 18 parts of pure gold and 6 parts of other alloying metals such as silver, copper and any other metal depending on whether it is rose gold colour, white gold colour or yellow gold colour. So in 18 carat gold, 18/24 = 0.750 which is a number that also characterises 18 carat gold.

What is carat gold?
The carat (abbreviation ct or Kt) is a measure of the purity of gold alloys. In the United States and Canada, the spelling karat is used, while the spelling carat is used to refer to the measure of mass for gemstones.Therefore 24-carat gold is fine (99.9 per cent Au w/w), 18-carat gold is 75 per cent gold, 12-carat gold is 50 per cent gold, and so forth.Historically, in England the carat was divisible into four grains, and the grain was divisible into four quarts.For example, a gold alloy of fineness (that is, 99.2 per cent purity) could have been described as being 23-carat, 3-grain, 1-quart gold.The carat system is increasingly being complemented or superseded by the millesimal fineness system in which the purity of precious metals is denoted by parts per thousand of pure metal in the alloy.The most common carats used for gold in bullion, jewellery making and by goldsmiths are:24 carat (millesimal fineness 999)22 carat (millesimal fineness 916)20 carat (millesimal fineness 833)18 carat (millesimal fineness 750)15 carat (millesimal fineness 625)14 carat (millesimal fineness 585)10 carat (millesimal fineness 417)9 carat (millesimal fineness 375)

Carat sizes are also expressed as “points”, with a one carat diamond equaling 100 points, a one-half carat diamond being 50 points, a three-quarter carat diamond being 75 points, and so on.
Is a 10k gold ring a homogeneous mixture or heterogeneous mixture?
A gold ring is generally considered a homogeneous mixture. It is either pure metal (gold) in the 24 carat version, or some alloy, or mixture of metals, in a lesser carat variety. The metals in an alloy ring will generally be distributed evenly throughout the object, and that will make it homogeneous.
