There are three varieties of Andradite: Topazolite、Demantoid and melanite.
Topazolite is yellow color Andradite. Demantoid is a chromium-containing Andradite, and melanite is a variant of titanium-containing Andradite.
Demantoid is the most famous Andradite, The origin may be Russia, Iran, Afghanistan, Namibia, Madagascar, etc. They have different colors.
Demantoid from the Ural Mountains of Russia is the most precious. Russian demantoid has a typical bright chrome-green color. Because it contains chromium, it is red under the CHELSEA COLOUR FILTER
Demantoid and Tsavorite are sometimes very similar, but the refractive index of Demantoid is up 1.81. If it is less than this value, consider Tsavorite or Mali garnet.
Topazolite is actually very rare, even rarer than Demantoid, but Topazolite is not as eye-catching as Demantoid, so the attention is not high.
More less people know melanite because the appearance of melanite is hard to like.
Demantoid from the Ural,2.2ct--0.9ct-0.9ct-1.8ct
Demantoid from Iran 2.65ct.
