Both are measurements used to demonstrate the value of the jewelry. Carat is the weight of diamonds and other precious stones, while a karat is the measurement of the purity of precious metals, namely gold. The purity of gold can be ranked from 1-24. For example, twenty-four karat gold is the purest form of gold.
The alloys combined in gold to make it harder and more useable are nickel, zinc, or copper. The color of the gold jewelry can recognize the presence of these alloys by a trained eye. Carat, on the other hand, is especially used for weighing diamonds. It is a measurement established on the commonly used metric system. A carat is split up into 100 points.
If a diamond is half a carat, then it is termed a 50 pointer. In 1907, the carat started being used as the appropriate legal standard for measuring gemstones. It is signified as Ct. Diamonds are mostly set in 18 k gold as the gold needs to be strengthened more to accomplish the diamond’s secure setting.
