Indigo gabbro, also known as "Merlinite", is a mineral conglomerate that occurs and is mined from the Norcross-Madagascar quarries in Madagascar. The typical colors of these basalt rocks are a deep indigo-purple and black. Indigo gabbro is a relatively new mineral to surface on the market for decorative purposes, such as carvings and polished materials.

The word "gabbro" refers to a large group of dark, coarse-grained, intrusive igneous rocks that are chemically equivalent to basalt. The rocks can contain a mixture of feldspar, chlorite, serpentine, muscovite, pyroxene, hercynite and magnetite within in a charcoal colored matrix.
