A superb skeletal galena specimen from this closed mine - 9th Septemvri mine, Madan ore field, Bulgaria – the only one that makes these structures. The skeletal structure is caused by very fast growth of the mineral where the crystal faces do not have the time to be completed because the edges grow faster than the center. It displays very attractive stepped growth, forming gorgeous terraced structures on all faces. The galena cubes are matt lustrous and light reflective. They are well formed and have a sharp geometry. On the galena are seen black tetrahedral sphalerite crystals and small quartz crystals proving the natural origin of the skeletal structure. It displays attractively all over 360 degree. In very good condition – some small contacts. On acrylic base.

Mesmerizing skeletal galena!
