Large Carlsbad-twinned Orthoclase (RARE) ex Sanabria Coll.

Item Description

Orthoclase crystals of this size, sharpness and quality are RARE from this area of the La Cabrera pluton near Madrid. This is an impressive sharply terminated crystal with variable orangy-tan to bone-white color and moderate luster. The striking sharp Carlsbad-twinned termination is a remarkable feature of this fine large rarity. The two excellent repairs, one near the middle and the other close to the bottom have minimal impact to the overall dramatic and excellent quality of this large rarity from the Sanabria Collection. valued?
