Decorative crystal chandeliers make spectacular feature lights and creative home owners and designers are using them nowadays in many rooms around the home. A few years ago it would have been unheard of to have a chandelier in your bathroom or kitchen! The beauty of crystal lighting relies on the prismatic refraction of light passing through the crystals creating the sparkle we all associate with lead crystal chandeliers. When the gradual build-up of dust and grime reduces this effect and your chandelier will begin to lose its sparkle.
