Famous as the source of the world's finest Cubanite specimens, the Henderson No. 2 Mine was a copper-gold mine open from 1960 until 1988. Cubanite from here is considered the world's best, by far...and most specimens are simply small. This is a relatively huge piece, a rare cabinet specimen, probably from the 1970s-1980s era. The Cubanites on this large, small-cabinet specimen range up to about 1.7 cm, and they have an excellent, metallic luster with a patina that ranges from bright and brassy to richly iridescent. The dramatic striations are very sharp, and they are the indicator of Cubanite's most distinct and desirable characteristic - its twinning. Known as 'trilling', it is the set of three adjacent, orthorhombic twins that together create a remarkable radial pattern that is its own type of 'sixling'. The one totally complete trilling is the unusually rectangular, 1.7 cm crystal that displays the full, 360 degree set of striations. All the crystals, each with their own unique 'look' among the lot, are set on a lustrous and iridescent piece of sulfide ore. Not fully identified from this mine until 1974, good Cubanites only trickled out of this mine while it was in production, therefore aesthetic and interesting examples such as this fine piece are rare. Considered classics in their own right, they are highly sought-after - and few of cabinet size even exist to be had at any price.
