A diamond carat differs from a gold carat. The gold carat indicates
purity – pure gold being 24 carats. One diamond carat, for mined or
synthetics diamonds, is 200 milligrams (0.007055 oz). The word carat
derives from the carob bean. Gem dealers used to balance their scales
with carob beans because these beans all have same weight.
