Cheap knockoffs use low quality glass. Such glass looks rough and lacks brilliance, consequently they need to rely on the bulb light to present the artistic patterns. Often times, the colors are not well coordinated in those lamps. This is because of the inconsistent nature of the low-end glass used, which makes it almost impossible to find the exact color variations.
On the other hand, a fine Tiffany style lamp is hand made with high quality stained glass that shines even when the light bulb is not on. The patterns are clear all the way through, and the light only enhances the beauty of the lamp. The texture of art glass is smooth. Colors are precise, consistent, and well balanced, bringing nature to life.
