Classic Brazilian specimen for the species, prismatic blue lustrous crystals of kyanite coming off a quartz matrix. In good condition all around.The Barra do Salinas district in Coronel Murta, Minas Gerais, Brazil, is part of a complex pegmatite province set within regional metamorphic rocks. Mining and collecting in this area focus primarily on its rich granitic pegmatites, which formed during intense regional tectonic and thermal events. The region is internationally famous among mineral collectors for producing some of the world's finest mineral specimens. Among these, the local kyanite is especially prized, occurring as exceptionally large, sharply formed, deep blue bladed crystals embedded within quartz or rock matrix. Small-scale artisanal mining and targeted specimen extraction have made these striking blue crystal groupings highly sought-after treasures for global museums and private collections.
