Diamond Grading Guide, The 4 C's

Understanding Diamond Grading: The Four C’s

This week, let's dive into the four C’s of the International Diamond Grading System: Color, Clarity, Cut, and Carat weight, with our comprehensive Diamond Grading Guide. Learn More from GIA.

A Brief History of Diamond Grading

In the 1500s, merchants used various vague terms to describe a diamond's value. These terms lacked consistency and clarity. However, the term “carat” has remained the standard measurement of weight from then to now.

In the mid-20th century, the Gemological Institute of America (GIA) established the first official standard for describing diamonds. This universally accepted approach made diamond evaluation clear and consistent. Our Diamond Grading Guide simplifies these standards, helping you understand the key aspects of diamond quality.

The Four C's Explained

1. Cut

The cut determines the amount of sparkle a diamond will emit. It's the most significant aspect of a diamond's beauty. A well-cut diamond reflects light in a way that maximizes its brilliance and sparkle.

2. Carat Weight

Precision is key when measuring carat weight. We measure to the hundredth decimal place, so a one-carat diamond is recorded as 1.00 carat. This precise measurement ensures accurate assessment and comparison.

3. Color

We use a scale that runs from D (colorless) to Z (light yellow or brown). These subtle differences can significantly impact the quality and value of a diamond. Colorless diamonds are rarer and more valuable.

4. Clarity

Clarity depends on how a diamond forms. Most diamonds have inclusions, or "birthmarks," that affect their value. Fewer inclusions mean higher clarity and greater value. Clarity is graded based on the size, number, and position of these inclusions.
