What does triple excellent mean?

Triple excellent means the diamond received GIA or IGI's highest grade — Excellent — in all three cut-quality categories: cut grade, polish, and symmetry. This combination ensures maximum light performance and represents the top tier of diamond cutting quality.

Is triple excellent worth the premium?

For round brilliant diamonds, yes. Cut quality has the single biggest impact on a diamond's beauty. A well-cut diamond of lower colour and clarity will always outperform a poorly cut stone with higher grades. Triple excellent ensures you are getting the best possible light performance from your chosen stone.

Do all shapes have triple excellent?

GIA only assigns a formal cut grade to round brilliant diamonds. For fancy shapes (oval, cushion, emerald, etc.), only polish and symmetry are graded. "Triple excellent" in the strictest sense applies only to rounds, though some IGI reports include cut grades for fancy shapes.

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.
