Crystal Energy Grid of Protection.
With the protective symbols of Solomon and its inlays of clear quartz as a base to amplify the crystals you choose to use on it.
This is a one off hand built energy grid with a centre that is capable of glowing in the dark to symbolise the power of the centre of the grid.
For protection against negative energies simply place our chosen crystals on the seven symbols of Solomon and your main crystal in the centre.
