large Hubnerite on Quartz ex Siber and Hefendehl Coll.

Item Description

The famous Huayllapon Mine at Pasto Bueno is generally considered to have produced the world's finest hubnerite specimens and well as world-class rhodochrosite. This impressive large combination is beautifully highlighted by the very aesthetically placed parallel-growth cluster of three classic tabular hubnerite crystals. The splendent, well-striated frontal crystal is 4.5 cm long and all the crystals have typical flat-topped terminations. The hubnerites are set on a dramatic large matrix of opposing glassy and lustrous, translucent to transparent quartz crystals. The two striking large parallel-growth quartz crystals with chisel terminations reach 8.3 cm, very large for the locale. Formerly in the collection of Kirby Siber, a member of the well-known Swiss mineral and fossil dealership, Siber+Siber (1970s). This exceptional large combination came out during the height of the hubnerite and rhodochrosite production at the Huayllapon Mine. Mass is 1834 grams or 4 pounds. Ex. Kurt Hefendehl collection.
