Peridot.  Thought to drive away the evil spirits at night.  This was because of how it reflected the candle light back before electricity.  Certified appraised at Harold Weinstein Labs for fair market value.  I have peridot stones that will be listed in the non certified section of this auction site that were taken from the same parcel as this stone.  They will be at further reduced prices.  Any stone purchased from me that appraises for less than you paid I'll refund that difference.  I sell to jewelry makers at trade.  Trade is 1/2 wholesale. 

This is not an appraised stone but was taken from the same parcel as the two stones I had appraised.  Please see other certified stones for appraised values.
