A brilliant cabinet-sized plate of twinned galenas, that look in quality like more modern material from Bulgaria with a brightness you seldom see in this older, Mexican find. Emplaced on a matrix of calcite holding together intergrown sphalerite are many upright galena crystals, to 3 cm across. Most of these galena crystals are also elongated spinel twins. The druse of white calcite provides marked contrast. Very striking and rare in such size, as a display specimen!
