You are looking at an amazing, Seraphinite / Clinochlore stalactite slice from Russia. There is a VERY tiny piece missing (shown with red arrows in photos) from this otherwise complete specimen. One side has been polished to accentuate its stunning chatoyancy. This is a very rare and special piece!
