Diamond Jewelry Education - The 4 C's - Carat

Carat weight is the standard unit of weight for diamonds. One carat equals 1/5 of a gram, or .007 of an ounce. Carat weight is further divided into decimals. For example, exactly 1/2 carat is .50 carat and expressed as 50 points. Because diamonds are weighed to hundredths of a carat, they must be weighed on extremely precise and sensitive scales. All other factors being equal, as weight increases, so does rarity and value.

In solitaires, we regularly carry from 1/10 carat up to 2.0 carat total weight (ctw) single stones. We also carry large total carat weight diamond jewelry items from diamond tennis bracelets up to 6.0 ctw for women and men, diamond fashion rings and anniversary rings in many sizes. If you need something larger or a combination that you do not find on our site, you can contact us with the specifics of what carat weight stone or combination you need and we will do our best to accommodate your specific requirement.
