"Desert Bloom" makes a strong impression with its rich color pallet and bold shapes and would make a beautiful statement in any home. The THC or tetrahydrocannabinol crystals are grown on a glass microscope slide by evaporation and then photographed through the microscope.  THC is a psychoactive component of the hemp plant, first domesticated over 12,000 years ago.  The crystal facets create the colors naturally by refraction of the transmitted light.
