What Makes a Diamond Valuable: Diamond Valuation Guide

Certain diamond characteristics significantly increase demand and value when you sell diamonds in the secondary market:

Certified Stones

Diamonds certified by GIA, IGI, or HRD command premium offers due to verified authenticity and recognized grading standards.

Cut Over Size

An excellent cut enhances brilliance and market desirability over carat weight alone. Superior cut quality dramatically impacts a diamond's overall appearance and value.

High Clarity

Stones with clarity grades of VS1 or better (Very Slight Inclusions) are most sought after by discerning buyers and collectors.

Superior Colour

D to G colour grades for white diamonds reflect higher purity and command stronger market value across all buyer segments.

Carat Weight

Diamonds of 1 carat and above typically receive greater buyer interest and premium pricing in today's market.

Desirable Cuts

Round, Oval, Marquise, Heart, Emerald, Cushion, and Princess cuts remain highly marketable and liquid in the secondary market.
