Our verdict

Emerald vs Demantoid Garnet

Durability

Emerald is the harder stone (7.5 – 8 vs 6.5 – 7 on the Mohs scale), so it resists scratches better in rings and daily wear. Demantoid Garnet still suits jewellery when set protectively.

Value

Emerald generally commands the higher price per carat. Demantoid Garnet offers comparable presence at a more accessible level, which is why many buyers consider it the smart alternative.

Colour

Emerald: Vivid green, coloured by chromium and vanadium. Demantoid Garnet: Vivid grass to emerald green, coloured by chromium.
