Demantoid Garnet
Demantoid is the rare green garnet whose fire outshines diamond — the gem of the Russian Tsars.
What is demantoid garnet?
Demantoid is a rare green variety of garnet with exceptional dispersion (fire). Fine stones can show characteristic 'horsetail' inclusions, which collectors actually prize.
History & why it matters
Discovered in the Russian Urals in the 19th century, demantoid became a favourite of Fabergé-era jewellers and Victorian designers.
What affects value
Vivid green, strong fire and (for Russian stones) horsetail inclusions raise value; demantoid is among the most valuable garnets. Browse antique gemstone jewellery.
