These Powerful Quartz Crystal Energy Grids/Generators measure approx 3 inches long by 3 inches wide They have some small inclusions both on the points and the pyramid - please note these are not cracks or breaks - just small natural inclusions that are part of the crystal itself They have a 1 inch quartz pyramid in the centre and the 4 single quartz points are attached to the grid with ornate silver tone findings The 4 main Usui Reiki Symbols are engraved hand carved on the side of the pyramid in Gold Coloured paint - Gives these beautiful power generators that extra power and makes them very protective and healing A good Reiki practice to clear a room is to draw the symbols with your imagination - but the grid does all this for you We are both Usui Reiki Masters at Ahimsa and the symbols are almost exactly the ones we were attuned to with very slight differences These beautiful grids would be excellent for therapy or meditation rooms and also for dispersing negative or stagnant energy Also fab too for placing around any electrical devices to keep the energy clear Clear Quartz is said to be the Master Healing Crystal as it holds all the colour rays The photos tell the story so we will leave you to ponder over the pictures we have taken
