I got this from the link above. Its the lithium based crystals. The web site is very informative.
Golden 'C'
(mined near San Diego, CA in late 1800's, a very special stone & extremely rare)
(35% lithium) - an extraordinary one-of-a-kind stone that is no longer available. Balances, aligns and blends all chakras. Stabalizes and balances extreme highs and lows. Supreme Orienter: top and bottom, left and right, front and back, inside and outside. Clears and purifies anything. BEWARE of those saying they are selling Golden 'C' if it doesn't come from the mining near San Diego in the late 1800's. We make and sell structured water from this stone. Read more...
Tourmaline
(1-1 1/2% lithium) - conducts electricity via striations. Most effective if naturally terminated. Applying pressure to a continuously heated stone will direct an electrical current. Useful placed on blocked meridian point or using light pressure on blocked meridian point with the terminated end of crystal. Documented as the second fastest conductor of electricity next to the human brain. Versatile because of the various color frequencies. A fairly new exciting variety named after the mine in Brazil, called Paraiba, is noteworthy because of its unique blue-green range of colors. Its essence is like the sea and I believe this stone's color frequency resonates powerfully at the thymus center.
Lepidolite
(3-5% lithium) - reduces worry and stress, soothes and balances emotions, connects heart and brow chakras and drains off excess electrical energy. Good placed in bath. Plants irrigated with water charged by strapping a stone on the pipes have produced larger crops and charged water helps heal some types of skin cancer. Caution: do not place directly in water when making an elixir for consumption; rather, place close to container of water. Do not place near flame as flourine gas is produced.
Lepidolite with Pink Tourmaline
(1-5% lithium) - Combines the properties of both lepidolite and tourmaline.
Lepidocrosite
Lepidolite needles in amethyst. All the properties of Amethyst with Lepidolite.
Rose Lepidolite
Lepidolite and mica. Has all the properties of lepidolite as well as mica. Mica is the second greatest conductor of magnetic energy next to the human brain. Since we are inundated with excess electrical energy in our environments, extra magnetic energy can help to balance the electromagnetic field of the body.
Sugilite
Also called luvulite or royal lazel from a manganese mine in South Africa. Connected with St. Germaine and the purple flame of transmuting negative energies. Activates thymus, spleen and pineal gland; balances the brain hemispheres.
Kunzite
(8-8 1/2% lithium) - also known as Pink Spodumene. Activates the heart chakra and balances emotions; supports throat and brow chakras. Sleeping with it prevents nightmares and helps dream recall.
Hiddenite
(8-8 1/2% lithium) - also known as spodumene or green spodumene. Over time when placed on the parotid gland in the cheek area, can relieve stored anger/rage; resolves TMJ and knee problems.
Amblygonite
(8-10% lithium) - helps remove pent up emotions, activates electrical system and transmutes negative energy. Tape on back of neck or pinch one in each hand with thumb and index finger for headaches or tape on thymus when working on computer terminal. Opens all chakras and meridians and rebalances all energy levels of the aura. Makes structured water in 15 minutes. Caution: do not put directly in water if making an elixer for consumption; rather place near container of water.
Lithium Quartz
(lithium content varies) - second most powerful lithium stone available today. Has all the qualities of quartz and more: has both left and right spin so repolarizes body and can send, receive and store information simultaneously. Self-cleaning so does not need to be cleaned as often as other lithium stones. Purifies water and also makes structured water by placing in water or next to container for 5-10 minutes. Is said to resonate with all notes of the musical scale and with all colors and all chakras, individually and collectively.
