It is a stained glass panel set. I made it with an image like a coat of arms. Also fits a simple interior. Glasses shine brightly in places where there is light, such as bay windows, and they look very beautiful. The central part is fitted with a transparent bevel. Light is reflected because the glass is cut diagonally. Iridescent colors appear on the ceiling and walls like prisms. (The rainbow does not appear on days when the light is strong or when the weather is bad.) Glass is an imported product made by Spectrum and Kokomo.
