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.

Percent purity is a unit for expressing the gold content in gold alloys, representing the percentage of pure gold in the total weight of the alloy. Percent purity provides a direct measure of gold content, with 100% representing pure gold and lower percentages indicating gold alloys with other metals. Percent purity is an alternative way to express gold content, complementing the karat system.

Converting percent purity to other gold purity units is essential for understanding gold content and jewelry specifications. Percent purity can be converted to karat values, with 100% equaling 24 karat, 75% equaling 18 karat, 58.33% equaling 14 karat, and 41.67% equaling 10 karat. Whether you're converting percent purity to karat values for gold content, working with percent purity measurements for jewelry specifications, or using a percent purity converter for jewelry calculations, percent purity conversions are fundamental to gold purity measurements.

Percent purity is used in jewelry and precious metals for expressing gold content. The percent purity unit's direct relationship to gold content makes it intuitive for understanding the actual gold percentage in alloys, providing an alternative to the karat system for expressing gold purity.
