Description

Indigo Gabbro is a combination of several minerals within its mix such as Chlorite, Muscovite, Serpentine, Feldspar, Magnetite and several other lesser known minerals and metal elements in usually a dark blue/grey matrix of Chalcedony. This places it in the trigonal crystal system in the mineral class of oxides in the quartz group. Most items in the market place today are coming from areas in and around Madagascar.

The Gabbro in its name refers to a large group of dark igneous rock made of silicate that’s rich in iron and magnesium. It Is usually in shades of black with grey colored mottling.

It should be noted that some are also referring to this one as Mystic Merlinite which is NOT a classified mineral name. It is a trademark label someone created for this type of stone.
