The design for this piece is a cross between an old Hopi drawing and a Tibetan Mandala. The polished aluminum tray the piece was built on is 18" in diameter. I added several colors of hand cut stained glass, as well as a number of beige glass jewels and one larger red glass jewel for the center point. The colors in the 4 quadrants were chosen to both compliment each other and enable a harmony within the whole piece.
