The optical crystal house paperweight is a stunning and unique decorative item that is crafted from high-quality, clear crystal. The paperweight is designed to resemble a small house or home, and the intricate details of the house are captured by the laser etching of the windows. The crystal house is 2-3/8" H x 2-1/4" W in size, and the optical crystal material used gives the house a beautiful, transparent appearance. The material used is also known for its high refractive index, which makes it perfect for creating optical illusions and visual effects. One of the most striking features of the optical crystal house paperweight is the use of a rainbow coating on the crystal. This coating refracts light in a way that creates a stunning rainbow effect, which is visible throughout the crystal. The rainbow coating is applied through a special process that involves heating and cooling the crystal, which creates a thin layer of coating on the surface. The paperweight serves both as a decorative item and a functional one, as it can be used to hold down papers or serve as a unique ornament for a desk or shelf. The optical crystal house paperweight with rainbow coating is a popular choice for gifts or as a collectible item, and is appreciated by those who appreciate the beauty of crystal and the art of glassmaking.
