Chalcopyrite on Quartz - rare old classic ex Hauck

Item Description

Clusters of metallic, golden Chalcopyrite richly adorn the Quartz-crystal matrix, from JAPAN. The crystallization of the Chalcopyrite crystals is complex, and they reach up to about 2 cm in size. The metallic luster is very good, the striations add to the faces. and the classic greenish-gold color is enhanced by flashes of multi-colored iridescence. Gemmy Quartz crystals up to 1.2 cm comprise the matrix that the Chalcopyrites rest on. This excellent and aesthetic combination is quite rare in this quality from Japan, and it is so good that looking at it brings up thoughts of some other fine Chalcopyrite/Quartz pieces from around the world from contemporary localities. However, this is from the late 1800s or early 1900s and an extinct location with much more appeal than modern finds, to my eye. It is also an unusually aesthetic example from here.. From the noted historic classics collection of Richard 'Dick' Hauck of New Jersey. valued $1200-1500. According to MINDAT: First worked in the late 17th century for silver ore, then during the 18th century for copper. In the 19th century it produced lead, zinc and cadmium, until it was closed in 1979. Reworked on a small scale in the 1980s for its banded rhodochrosite as lapidary material.
