supplement the energy of other gemstones.  The Diamond will increase the
 power of the Emerald and the Amethyst to a higher level.  Healers often
 have rings or necklaces set with Diamonds surrounding the Amethyst.
Care must be used when wearing a Diamond necklace as it can block the 
energy flow if the wearer has negative thoughts or feelings.
