Diamond FAQ

The 4Cs are how all diamonds get graded: Cut, Color, Clarity, and Carat. Cut is how well it's shaped (this affects sparkle the most). Color goes from D (totally colorless) to Z (yellowish tint), though anything D through J looks white in a ring. Clarity is about tiny flaws inside—most are invisible without a jeweler's loupe, so VS1 or VS2 is plenty. Carat is just weight. Here's the trick: get an Excellent cut first, then aim for G-H color and VS2 clarity, and spend whatever's left on the biggest carat you can afford. Start your diamond search to compare options.
