Tetrahedrite with Dolomite
Huanzala Mine, Huallanca district
6.5 x 5 x 1.8 CM (cabinet)
A particularly esthetic Tetrahedrite with very sharp crystals over 3 CM. The main crystals are flattened Tetrahedra and have very good luster, distinct striations and a good metallic sheen. In fine condition, the front or main face is clean and undamaged, there is contacting on the back and outer side edges that is not seen on display. Impressive specimen of this usually non-esthetic Sulphide specie, Very choice for the locality and a fine Tetra from anyplace.
Metallic and bright lustrous these very sharp crystals are sprinkled with a few small quartz and pyrite crystals. Individual tetrahedrons up to 2.7 CM are jumbled in a complex arrangement on this matrix plate. In fine condition overall for this delicate mineral, only one crystal has an edge bruise, all others are perfect, complete and pristine. Really hard to find this level of quality at any price.
