Dumortierite
Dumortierite is a beautiful blue-grey stone similar in color to other blue stones Lapis and Sodalite. First described in 1881, the stone is named after French paleontologist Eugène Dumortier. The stone’s chemical makeup is Aluminum Boro-Silicate Hydroxide and it sometimes is found in quartz as inclusions. It’s found all over the world like Brazil, the US, Europe and Canada, with most mined rough being cut and polished in East Asia. Fun fact, because of the high aluminum content in Dumortierite, the mineral has been used in the manufacture of high grade porcelain for spark plugs!
