A thumbnail specimen (2.3 cm) of mellite crystals Csordakuti mine Hungary.

Very uncommon on the market, this is a very large and fine crystal of the unique,organic-based mineral mellite, most of which come from Hungary . This one has textbook form and fine luster. There is contact on one tip and on the back, but a really good display face. You just do not see these for sale often! 3.2 x 2.8 x 2.3 cm

A 3.4 x 2.9 x 2.8 cm pair of euhedral, intergrown tetragonal dipyramiod crystals of mellite from this classic location. The largest crystal is 2.9 x 2.9 x 2.8 cm. Translucent honey-colored crystals with black inclusions from the lignite.

4.5 x 3.2 x 3.2 cm. Mellite is actually an organic compound, an aluminum mellitate (benzene hexacarboxylate) hydrate, a rare secondary mineral in lignite deposits. Crystals of this quality are seldom seen and almost exclusively come from this small mine and are certainly the best-of-species. It is believed that most mellites from here were mined ...

An unusual specimen of a very soft (mohs hardness 2- 2.5) organic compound of Aluminium - Mellite - forming pretty, transparent honey brown to white crystals. The whole specimen possesses an eye catching vitreous lustre, and the tetragonal crystals are sharply formed and measure up to 12mm in size. White crystals are relatively rare for the ...

Dimensions: .75" x .75" I think Alexander von Humboldt got ripped off. The rare organic mineral named after him, Humboldtine, is obscure, and, at its best, not much to look at. This specimen resembles a pellet of yellowed deer scat. His fellow German and man of letters Goethe, after all, got Goethite, which is quite widespread and often ...
