Understanding Diamond Carat: Weight and Perceived Size

Read this guide before choosing your engagement ring

When evaluating a diamond, carat weight is a key measure that reflects the weight of the stone. One carat is precisely 200 milligrams or 0.2 grams. To ensure precision, each carat is further divided into 100 “points,” allowing for highly accurate weight measurements. For instance, a 0.75-carat diamond equates to 75 points, while a 0.50-carat diamond—commonly referred to as “half a carat”—equals 50 points.

The Role of Carat in a Diamond’s Appearance

While carat weight is often associated with the size of a diamond, it’s essential to recognize that weight alone does not always dictate a diamond’s visual size. Factors such as shape and cut play a significant role in how large or small a diamond appears to the eye. This understanding is vital for buyers who seek the presence of a larger diamond while balancing their budget.

Key Insight:

For many buyers, carat weight is a major factor when choosing a diamond. However, achieving the perfect balance of beauty, quality, and value requires considering not just the carat weight but also the cut, color, and clarity. This comprehensive approach ensures that the diamond meets size expectations while offering exceptional brilliance and visual appeal.

Key Takeaways:

  • 1 Carat = 200 milligrams (0.2 grams).
  • Points System: Diamonds under one carat are measured in points, with 100 points equaling 1 carat. For example, a 0.75-carat diamond weighs 75 points.
  • Perceived Size: While carat weight influences size, factors like cut and shape can affect how large a diamond appears.
