Here are some Black Obsidian Pyramids that have been damaged in the shops or at markets. So if you are more interested in the shape at a good price than perfection, then maybe one if for you. I have no means of repairing them.
The worst damaged has the clearance discount.
To read the meaning of this stone go to the Healing Tab about the benefits.
To make it easier, I created a video of them so you can see the nicks and dings as well as one with inclusions.
I also have them in the obelisk shape, and as silver sheen towers.
So how about a black obsidian pyramid like these to suit your needs?
