Microcline (large Baveno twin)

Item Description

Here is a rather impressive specimen for the Feldpsar collectors out there. This is from a find in Pakistan near the end of 2005. This is something that is not often seen from this country, or any country for that matter. This specimen features a fine quality, large, thick / blocky, sharp, lustrous, porcelain-esque "Baveno" twinned crystal of Microcline associated with thin black Schorl crystals and colorless Quartz prisms. It's actually a near "floater" as it's healed / recrystallized on the reverse side, so it virtually crystallized all the way around. "Baveno" twins occur in Feldspars around the world, but are quite scarce in such THICK hefty crystals with such excellent form l;ike this. The twinning occurs when crystals are elongated along the b axis, and the diagonal twinning plane 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 incredibly hard to obtain from Pakistan, especially is such large, impressive examples. Simply put, this is a fantastic twin with excellent form, and looks like a beautiful piece of marble. Valued at $2,000 for the size and quality.
