Dark Green Black Grandidierite Cabochon

A rare and dramatic Dark Green Black Grandidierite Cabochon, displaying the deep, shadowy green-black tones that emerge from one of the viewing axes of this remarkable trichroic gemstone. Grandidierite is one of the world's rarest minerals, and its trichroic nature means it can display three distinct colors depending on the angle of light — blue-green, colorless, and dark green to black. This cabochon leans into the stone's darkest, most intense tones, creating a bold and mysterious appearance that sets it apart from lighter Grandidierite specimens.
