This is a simple string necklace with a Herkimer Diamond pendant set in (plated) Gold, with a silver closure. The Herkimer Diamond is the “attunement” stone; it manifests pure life force energy. This string necklace is a piece of high energy around your neck; Herkimer Quartz “Diamonds” are the high energy seekers of the crystal world. Herkimer Diamonds are the most powerful of all Quartz crystals; being doubly terminated, they have the ability to not only transmit their own energies, but to receive spiritual energy and to amplify and focus it intently.
