The 4Cs
Understand what you're actually paying for.
We wrote the plain-English 4C guide we wished existed when we were buying our first stone.
Read the full guide →The only C the diamond cutter controls. Precision here is 60% of visible sparkle.
D–F is colorless; G–J is near-colorless. Most eyes can't distinguish above H.
VS1 and above is eye-clean at arm's length. SI1 often is too, at half the price.
Weight, not size. A well-cut 0.95ct can look larger than a bulky 1.10ct.
