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. 
 
The Herkimer Diamond is an "attunement stone," useful for attuning to another person, group or environment. It is particularly beneficial to use before the "laying-on-of-stones," or other healing situations when the practitioner and subject are not well acquainted, and is an exceptional crystal for linking people together who have to be apart. 
 
Herkimer is a good crystal for teachers of spirituality and alternative therapies. As a power stone in the workplace, it brings positive attention and prosperity through high achievement, and assists with research and study as it stores knowledge. It is also beneficial in stabilizing company finances.
