Diamond karat (ct) is a unit of weight used for gemstones, particularly diamonds, equal to 200 milligrams or 0.2 grams. The karat for gemstones is different from the karat used for gold purity. One diamond karat is divided into 100 points, so a 0.50 karat diamond can also be described as 50 points. Diamond karat is one of the "Four Cs" used to evaluate diamond quality, along with cut, color, and clarity.

Converting diamond karats to other weight units is essential for understanding gemstone weights and jewelry specifications. One diamond karat equals 200 milligrams, 0.2 grams, 0.00705479 troy ounces, or 3.08647 grains. The diamond karat to gram conversion is common for weight measurements, while diamond karat to milligram conversions are fundamental for precise gemstone weights. Whether you're converting diamond karats to grams for weight measurements, diamond karats to milligrams for precise weights, or using a diamond karat converter for jewelry calculations, diamond karat conversions are fundamental to gemstone weight measurements.

Diamond karat is extensively used in jewelry for measuring gemstone weights, particularly diamonds. Jewelers specify diamond sizes in karats, with larger karat values indicating larger and typically more valuable stones. The diamond karat unit's relationship to weight makes it essential for understanding gemstone sizes and values, providing a standard unit for measuring gemstone weight in the jewelry industry.

The grain is a unit of weight used for precious metals and gemstones, equal to approximately 0.06479891 grams. The grain is one of the smallest units used in jewelry and precious metals, providing precision for measuring very small quantities. One grain equals 1/480 of a troy ounce or 0.32399455 diamond karats.

Converting grains to other jewelry weight units is useful for understanding very small precious metal and gemstone weights. One grain equals approximately 0.06479891 grams, 0.00208333 troy ounces, 0.00208333 pennyweights, or 0.32399455 diamond karats. The grain to gram conversion is fundamental for weight measurements, while grain conversions help communicate very small weights. Whether you're converting grains to grams for weight measurements, grains to troy ounces for precious metal weights, or using a grain converter for jewelry calculations, grain conversions are useful for very small jewelry weight measurements.

The grain is used in jewelry and precious metals for measuring very small quantities. The grain's precision makes it useful for expressing tiny weights, though grams and larger units are more commonly used for most jewelry applications.
