Microcline (''Baveno'' Twin) with Aquamarine

Item Description

The prolific Pingwu Mine in China is best known for its world-class Scheelites, Aquamarines and Cassiterites, but here we have less commonly seen example of crystallized Microcline as the principal species. What's more, the Microcline has formed with an excellent "Baveno" twin habit, featuring smooth, well-formed, lustrous faces and a white porcelain-esque appearance. To top it off, the piece is highlighted by a thick tabular gemmy light blue crystal of Aquamarine measuring 3.0 cm, flaring off the side. A minor amount of colorless Quartz and bladed silvery Muscovite can be seen on the back. No damage that I can find on the top/display side of the piece. A truly eye-catching and hard to find specimen from this classic Chinese locality. Valued $2,500.
