A Picture through...a paper tube Indicolite
This faceted mineral specimen is inside a magnifying box and framed by a cardboard tube. It is a blue form of the mineral tourmaline. Indicolite is a very rare complex magnesium iron boro-aluminium silicate hydroxide mineral. This Tourmaline variety gets its color from tiny iron impurities and has only a few known localities throughout the world. Brazil, Nigeria, and Afghanistan have the most important active deposits. Happy Crazy Tuesday.
