Triple Excellent Natural Diamonds

A "triple excellent" diamond has received the highest grade — Excellent — in all three cut-related categories: cut, polish, and symmetry. This is the pinnacle of diamond cutting quality and represents the top tier of light performance.

Triple excellent diamonds maximise brilliance (white light return), fire (spectral colour dispersion), and scintillation (the sparkle pattern as the diamond moves). Only the most precisely cut diamonds achieve this combination, and they are particularly sought after for engagement ring centre stones.

At MOH London, our triple excellent collection is pre-filtered to show only diamonds that meet this exacting standard. Every stone is independently certified by GIA or IGI with all three grades confirmed as Excellent.
