Our luxury chandeliers are generally composed of aluminum and crystal or iron and crystal, with rich shapes. We do not use ordinary glass to replace real crystal. The quality of the two is very different. K9 crystal is the best crystal. The light is good, the refracted light is as uniform and translucent as a diamond. Although the glass surface is similar to crystal, the refracted light is very weak and does not give off a sparkling feeling. We often use them as decorations to create a luxurious atmosphere.
