This is a fully customizable piece. When you purchase this piece you will send us an email. This email will tell us which 8 angels you would like us to conjure into this piece for you. Each of the crystals will hold the presence of one angel. Our master conjurer will be making this piece for you, so you know that it will be done and done properly. He is one of the best of his kind. You will have to do a little bit of homework with this piece, because you will need to know which 8 angels you desire to conjure, what powers they hold, etc. Then, you will simply meditate with this piece in order to bring the angelic presences forth.
