Spurrite is a white, yellow or light blue mineral with monoclinic crystals.

[5] Spurrite is generally formed in contact metamorphism zones as mafic magmas are intruded into carbonate rocks.

It is biaxial with a birefringence of 0.0390–0.0400, giving second order red interference colors when viewed under crossed polarizers in a petrographic microscope.

[6] Spurrite was first described in 1908 for an occurrence in the Terneras Mine, Velardeña District, Durango, Mexico.

It is also found in Ireland, Scotland, New Zealand, Turkey, Israel, Japan and Siberia.
