Daily Wire Jewelry Making Tip


I would like to know how to convert carats to grams. Is it possible, or is the weight too small?

-Linda in Sherman, Texas


Not at all, Linda. 1 carat = 1/5 gram, so 5 carats = 1 gram.

Simply divide the number of carats by 5 to find the grams. So a gemstone that weighs 53 carats would be 10.6 grams.

For more difficult carat-to-gram conversions, check out this easy Carat to Gram Conversion Calculator.

    Some factoids: Carat and Karat derive from Carob – a fruit indigenous to the Middle East. Most websites state that the small, very hard seed was used as a standard for gemstones. Other websites state that the seeds were never specifically used. The word carat comes from the Greek – keraton (which also means little horn) but is ultimately from the Arabic – charuv – dry. Just thought you should know.

    Those seeds were used as a standard for measuring gemstones because each seed had exactly the same size and weight as the other. They all were (are) all exactly the same!
