Microcline (large Baveno twin) with Schorl

Item Description

Here an impressive specimen for the Feldpsar collectors out there. This is from a find in Pakistan in the late Fall of 2005. This is something that is not often seen from Pakistan. This specimen features a fine quality, sharp, lustrous, porcelain-esque "Baveno" twinned crystal of Microcline associated with minor black Schorl crystals. "Baveno" twins occur in Feldspars and are quite scarce in such THICK crystals with such excellent form. Baveno twin crystals are elongated along the b axis, and the twinning plane, a diagonal one, runs through opposite edges of the prismatic crystal. The name of this twin comes from the locality in Italy where this twin was first observed. These twins are very hard to obtain from Pakistan, especially is such large, hefty examples.. This piece is a great quality "Baveno" twin with excellent form, and looks like a beautiful piece of marble. Valued at $2,500.00 for the size and quality.
