Understanding Carat Weight

The term **carat weight** refers to the actual physical weight of a diamond — not its size. By definition, **1.00 carat** equals precisely **200 milligrams**, or 0.2 grams. This precision is vital for determining value.

The term **‘points’** is sometimes used for smaller diamonds, particularly under a carat. For simplicity and standard industry practice, **100 points = 1 carat**.

Each diamond’s weight is meticulously measured and listed in carats, following international trade standards set by organizations like the GIA.

Did you know? Two diamonds of equal carat weight can appear different in size depending on their **cut** and **proportions**.
