Hi. My name is Andy. I'm a geologist from Canada who has been collecting minerals for decades and now I have added meteorite collecting to my hobby. This blog is loaded with photos of my personal collection of minerals and meteorites. I have also been adding my own photos of what I think is cool and interesting geology. Unless I indicate otherwise, all the microscope photos and macro photos have been taken by myself. Please use the "Ask me anything" option to leave comments or questions. I'd love to hear from you.

KYANITE (Aluminum Silicate) from Minas Gerais, Brazil. These blue crystals of kyanite have a unique hardness characteristic. Unlike most mineral crystals, kyanite is strongly anisotropic. It exhibits a significantly different hardness parallel to the long axis of the crystal ( ~ 4.5 to 5 mohs scale) than perpendicular to the long axis of the crystal (~ 6.5 to 7 mohs scale). Most commonly the crystals are blue, as shown in these photos, but can be green or shades of white/gray.
