Know Your Diamond: The 4 Cs
Ten minutes of education saves thousands of dollars. Here's what actually matters when you compare stones.
Cut
The only C shaped by human hands — and the one that decides how a diamond returns light. Prioritize this first.
Color
Graded D to Z. We'll show you side by side where the eye actually stops noticing the difference.
Clarity
Most inclusions are invisible without a loupe. Buy the grade you can see, not the one on paper.
Carat
Weight, not size. A well-cut stone can look noticeably larger than its carat suggests.
