1. Cut: The Sparkle Factor
What It Means
The cut refers to the craftsmanship involved in shaping and polishing the diamond, affecting how it captures and reflects light. A well-cut diamond maximizes brightness and sparkle, giving it that unmistakable dazzle. Cut grades range from Excellent to Poor.
Popular Cuts
Here are some of the most popular diamond cuts:
- Round Brilliant: The most popular cut, known for its exceptional sparkle and fire.
- Princess: A contemporary square shape that offers brilliance with clean lines.
- Emerald: Features a rectangular shape with step cuts, providing a sophisticated, vintage look.
- Radiant: Combines the elegance of the emerald cut with the brilliance of a round cut, ideal for those seeking a unique shape.
- Pear: A teardrop shape that can elongate the finger, offering a romantic appeal.
- Oval: Similar to the round cut but elongated, providing a larger appearance for its carat weight.
2. Color: Pure and Clear or Unique and Warm
What It Means
Diamond color actually refers to the absence of color. Most diamonds are graded on a scale from D (colorless) to Z (light color), with colorless diamonds being the rarest and most valuable.

How to Choose
If you’re seeking a classic, colorless look, aim for a grade between D and F. G to J grades offer a nearly colorless appearance but are often more budget-friendly. For those who like a bit of character, slightly colored diamonds can pair beautifully with warm-toned settings.
3. Clarity: Flawless or Character-Enhanced
What It Means
Clarity evaluates the presence of internal characteristics (inclusions) and surface blemishes. These natural features make each diamond unique. The clarity scale ranges from Flawless (FL) to Included (I), with fewer inclusions considered more desirable.
