The Dow was named after Jane Ann Dow by her friend and fellow crystal worker and author, Katrina Raphaell. They are also known as Temple heart crystals. These are usually one in 50 crystals, they are quite rare.
They have three 7 sided faces alternating between 3 x 3 sided faces, so the configuration of faces at the termination are 3,7,3,7,3,7.
Dow crystals with three-axis of symmetry are special in that they channel christ's consciousness energy, the energy of the trinity. They have strong pure energy about them that is sharp, clean, and direct.
They also hold the energy of the high priestesses of Lemuria and the ascended masters, and generally are for enlightened Lemurian healing work. They open us to true healing from the heart, signifying quantum leaps in consciousness, compassion, and love.
