Description

Quartz (Japan Law Twin)
PC Mine, Cataract Mining District (Comet Mining District; Basin Mining District), Jefferson County, Montana, USA
8.2 x 4.2 x 1.9 cm (3.23 x 1.65 x 0.75 in)

A petite but spectacular Quartz specimen with very well-defined Japan Law twinning, presented aesthetically atop a flat Quartz sliver, which has been completely recrystallized-making this piece a complete floater! Along with a striking transparency, the twinned Quartz shows very well-defined phantoms at the center of each growth, almost perfectly outlining the terminated crystals. The PC ("Perfect Crystal") Mine is best known for its Japan Law Twin Quartz specimens, of which this piece is a superb example.

From the collection of Daniel "Dan" R. Kennedy.


More Information: This piece is in excellent condition.
