DIAMOND-LIKE DEMANTOID
The star among the green garnets is the rare demantoid. Its name comes from the Dutch
and basically means “diamond-like”. Not without reason, because the demantoid is the
most precious of the garnets and one of the most valuable gemstones of them all. It is particularly
remarkable for its unusually high dispersion; in other words, its ability to refract
light penetrating the facets into all the colors of the rainbow. The fabulous play of light
and colors demonstrated by the demantoid is even more impressive than the diamond.
