Quartz (Variety Citrine)  Dauphiné twinned crystal.  Chaffee County, Colorado.  These crystals were found by friends in 2017.  They are true citrine.  The color is light and the crystals surfaces slightly frosted, however, natural citrine is a rather rare thing.  This point is 5.4 cm long.  The internal white veils are caused by microscopic water bubbles.  No damage.  $40
