The term carat is rooted in the Greek and Arabic names of the ruin tree – KIRISHN in Greek and Carat in Arabic. Carat refers to the actual diamond weight unit. The more carat weight, the greater the size of the diamond, and the higher its cost.
It is important to note that the term “carat” as a diamond standard is a unit of weight measurement, and it differs from the term “karat” in gold, as it refers to its purity degree.
Dimensions play an important role in the appearance of diamonds. In addition to carat weight, the distance above the top of the diamond must also be taken into account. The common misconception is that half a carat is half the size of a single carat. In fact, half a carat is half the weight of one carat. Although carat weight may indicate the size of the diamond, the shape and cutting of the stone also play a major role in determining the size of large or small stones.
