Indigo Gabbro jasper is also known as Merlinite. 
It is a volcanic stone form Madagascar, holding a violet sparkle to it.

A stone of wisdom and connection to greater awareness.  As with its colour, Gabbro taps in to darkness.  It is known to open your mind to dark moments of your past, not to be relived but to ponder and learn.  In that there is wisdom, growth and strength.
