Understanding Diamond Points: How Diamonds Are Measured and Classified
Diamonds are measured in carats, but a very common unit used to measure diamonds is the "point." Understanding diamond points is essential for anyone who wants to invest in high-value, high-quality jewelry. In this guide, we explain what diamond points are and how they influence the value and look of a piece.
What Are Diamond Points?
Points are a subdivision of the carat, the standard unit of weight for diamonds. One carat equals 100 points, which means that a 0.50-carat diamond, for example, weighs 50 points. This measurement allows greater precision when describing smaller stones, which are frequently used in delicate ring, necklace, and bracelet designs.
For example, our Duo Diamond Ring, an exclusive piece, features two set 3.5 mm diamonds (16 points each), highlighting the perfect balance between minimalism and sophistication.

Why Do Points Matter?
Points help determine the size and value of a stone. Diamonds with more points are generally larger, but the cut and quality of the stone also influence its brilliance and final value. A 25-point (0.25-carat) diamond can have a different value depending on its color, clarity, and cut.
In addition, pieces such as the Our Lady of Aparecida Pendant with Diamonds and Sapphires (Our Lady of Aparecida is the patron saint of Brazil) show how small diamond points can be used to create delicate details in fine jewelry, elevating the design and adding value.
