What is a carat? It’s a unit of measurement used to determine purity and, ultimately, quality. Listed as a proportion of one twenty-fourth, it’s the reason the highest quality gold is 24 carat, and going back to ancient Greece, a keration was a carob seed that almost always weighed 0.2 grams, or one carat, which is how we measure diamonds.
