Color grades run from D (completely colorless) to K (faint warmth). D–F are colorless, G–H are near-colorless and look icy white in any metal, I–K pair beautifully with yellow and rose gold.

Clarity measures the tiny natural characteristics inside a stone. FL and IF are flawless; VVS and VS inclusions are invisible to the naked eye; SI stones can be excellent value when chosen carefully.

Carat is weight, not size — a 1.00 ct round is about 6.4 mm across. Elongated shapes like oval, pear and marquise look larger for their weight because they spread across the finger.
Shape is a matter of taste. Round brilliants are the most sparkly; step cuts like emerald and asscher are quieter and architectural.
Both are real diamonds with identical chemistry and sparkle. Lab-grown stones are created above ground in weeks and typically cost 60–80% less for the same specifications. Natural diamonds formed over billions of years and hold traditional rarity value. We grade and warranty both identically.
Every diamond ships with an independent grading report from IGI, GIA or GCAL, and its report number is laser-inscribed on the girdle so you can verify it yourself.
