Marysvale District, Piute County, Utah, USA
White crystals of sharply terminated stilbite form over quartz crystals which then transition into a forest green chalcedony. The edges of the piece show that the stilbite formed as a later mineralization over clear quartz crystals. The deep green chalcedony gives a nice and unusual contrast to this piece which is from the unusual stilbite locality of Utah, USA.
