rare black tourmaline, schorl grown in rose quartz and pink feldspar

A rare specimen featuring black schorl tourmaline embedded in a matrix of rose quartz and pink feldspar. A three-mineral constellation from the pegmatite deposits of Minas Gerais.

Schorl is the sodium-iron-containing tourmaline variety, crystallized in pegmatite as black columns with characteristic longitudinal striations. Rose quartz and pink feldspar (presumably microcline in the amazonite variety or Mn-containing albite) form the matrix.

The pink coloration of the accessory minerals is due to traces of manganese or titanium during crystallization. The three-component constellation is a deposit sensation because it documents synchronous mineralization of three different mineral families.

Brazilian pegmatite deposits in Minas Gerais are world-renowned for such polymineralic aggregates. A 66 cm specimen length is a museum-quality collector's dimension.

A collector's item with complex pegmatitic genesis and visual color constellation.
