This is a Triangle crystal grid made out of Birch wood. These are made to order, you can choose between approximately 4, 6, 8, 10, 12, and 14 inches in diameter and 1/4" thick. This is just for the grid, stones much be purchased separately.
There is an old symbol, much older than anyone can remember, beyond Christianity, beyond Rome, Greece and Mesopotamia. It is known as the Vesica Piscis symbol. Latin translation calls it the fish bladder. But don't be detoured by this name. Looking like two circles overlapping one another, it has been called the symbol of the 'fish' (because it is shaped like one where the circles overlap) or 'the eye of God,' because it looks like the shape of an eye, as well. I call it The Eye. Eye of Horus, for example. There are many 'eye' motif's and myths/legends around the world.
The Vesica Piscis is easily one of the most profound geometrical images of ancient and modern times. It is, for example, considered to be an integral part of the Ark of the Covenant, as described and shown figuratively by ka-gold's version of the Vesica Piscis. The latter article, in fact, ties in rather nicely with the so-called Hourglass Nebula described at the end of this Alexandrian webpage.
When the Vesica Piscis is viewed horizontally, however, the mandorla becomes a different sort of passage: the birth passage. The pointed oval is a universal symbol of the Divine Feminine, and in this context the Vesica Piscis is the vulva of the Goddess, surrounded by the crescents of the waxing and waning moon. The mandorla as birth passage can easily be seen on the sheila-na-gig figures found on Irish churches, and in the squatting figures of the Hindu goddess Kali. Almonds are a primeval fertility symbol, and as such are associated with the Phrygian goddess Cybele and her transgendered consort, Attis, and the Greek nymph Phyllis, who was metamorphosed into an almond tree. Fish, too, play a significant part in the lives of goddesses from many cultures. "Delphos" translates from Greek as both "womb" and "dolphin." The Chinese Great Mother Kwan -Yin often appears as a fish goddess, as does Aphrodite. Kali, as the swallower of Shiva's penis, becomes Minaksi, the fish-eyed one; Isis becomes Abtu, the Great Fish of the Abyss, when she swallows the penis of Osiris.
Crystal grid and healing sets are groups of stones that go together for a purpose. Sets of crystals and stones are used for ritual magickal or spiritual crystal healing purposes or with Reiki-Seichim energy work for healing. Some are generalized and others have specific purposes.
