Description:

Demantoid is a rare and highly valued variety of garnet, known for its brilliant green color and exceptional sparkle. It belongs to the andradite group of garnets and gets its vivid green color from traces of chromium and iron. The color can range from yellowish-green to deep emerald-like green, with bright, intense green stones being the most prized.

One of demantoid’s most remarkable features is its high dispersion, meaning it breaks light into rainbow-like flashes more strongly than diamond. This gives the stone exceptional fire and brilliance when properly cut. Demantoid has a vitreous to adamantine luster and is typically transparent.

On the Mohs hardness scale, demantoid garnet ranks about 6.5 to 7, making it softer than ruby or sapphire but still suitable for jewelry when worn with care. Many natural demantoids contain unique internal inclusions called horsetail inclusions, which are fine, radiating fibers that are highly valued and help confirm natural origin.

Demantoid garnet is found in locations such as Russia, Namibia, Madagascar, and Iran. Russian demantoids, especially those with horsetail inclusions, are considered especially rare and valuable.

Because of its rarity, vivid color, and remarkable brilliance, demantoid green garnet is considered one of the most beautiful and collectible gemstones in the world.
