Beveled glass is a glass or mirror that has an angled surface cut around its periphery. It is usually thicker than unadorned glass. The tapered edges of the glass help in accentuating the frame, thus giving it a unique beauty that can only be described as an old-world charm. What makes beveled glass design so unique is that the angled cuts or bevels allow the glass or mirror to act as a prism when the sunlight hits it. This creates beautiful color diffraction where you can see a wide spectrum of colors resembling a rainbow. You wouldn’t see this in clear, unadorned glass.
