Blue Kyanite in Quartz – Minas Gerais, Brazil – 0.45 lbs

A striking natural specimen featuring vibrant blue kyanite crystals emerging from a matrix of translucent white quartz, collected from the mineral-rich state of Minas Gerais, Brazil. While the exact mine is unknown, specimens of this quality and crystal association are most commonly attributed to the pegmatite districts of Minas Gerais, one of the world's premier sources for fine crystallized kyanite.

The contrasting deep blue kyanite blades against sparkling quartz create a dramatic display piece that showcases the unique crystal habit of this fascinating mineral. Kyanite's elongated bladed crystals exhibit exceptional natural texture and luster, while the surrounding quartz provides both visual contrast and geological context.

This specimen is an outstanding example of Brazil's world-renowned pegmatite mineralization and makes an impressive addition to any fine mineral collection.

About Blue Kyanite

Blue kyanite is an aluminum silicate mineral prized for its distinctive bladed crystal habit and rich sapphire-blue coloration. It forms under high-pressure metamorphic conditions and is widely recognized as an important index mineral used by geologists to understand the temperature and pressure history of metamorphic rocks.

Brazil, particularly the state of Minas Gerais, is internationally renowned for producing exceptional mineral specimens from its extensive pegmatite districts. Blue kyanite from this region is especially valued for its vivid color, elongated crystal blades, and attractive associations with quartz.

Unlike many minerals, kyanite possesses a unique physical property known as anisotropic hardness, meaning its hardness varies depending on the direction in which it is tested—a characteristic that makes it especially interesting to both collectors and mineralogy enthusiasts.
