Herkimer diamond necklace

Herkimer Quartz "Diamonds" are the high energy seekers of the crystal world.
Unusually transparent with a brilliant sparkle, they manifest pure,
solid Light and are powerful amplifiers of spiritual energy.
As perfect conduits of the universal Life Force, they are exceptional healing crystals,
and are used in meditations, dream and vision work, and advanced spiritualization applications.

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.
They are reported to be harder than all other Quartz,
giving them the strength and durability to handle difficult challenges beyond the scope of other Quartz crystals.
What they lack in physical size, they more than make up for in spirit energy.

The size is 2.2 x 2.1 x 1.7 CM
