"Ever since the Stone Age, emerald has been regarded as the most divine of all precious stones.  This gemstone is magnificent for regeneration and rejuvenation and deserved special attention for its healing effect on vision.  The emerald promotes harmony and hope (preciousltd)."

"Since 1986 when emerald prices soared, the miners in Columbia began breaking each and every rock they found in order to search for more valuable green.  Many fine specimens get smashed in this unfortunate manner.  One must also consider the untold number of emeralds that get smashed by geologic forces during the 200-plus millions years of geologic upheaval.  The incredible journey from crystallization deep beneath the surface to being geologically upthrust to where human will find them is a journey of both hazard and destiny.  This makes all natural emerald in matrix specimens special, rare and unique.  They are as old as a mountain and a treasure to revere."
