Thank you for the compliment on the wall art. I made it myself very inexpensively. I purchased the frames at Target. Then, I purchased the agates at Z Gallerie. They sell them as coasters and they come in a variety of colors such as brown, purple and blue. I recommend that you take the glass out of the picture frames because the thickness of the agate makes it difficult to secure the back of the frame once the agate is glued down. If you want to save yourself the trouble, Z Gallerie sells agate artwork already made up.
