Beauty of crystal often through its color, luster, transparency, refraction and the shape of cut set off. Because crystallization often contain inclusions within the crystal, double-crystal grain, crystal structure defects, resulting in optical interference, diffraction, scattering and other phenomena occur in the light of some special optical effects, to make crystals more beautiful, but also to improve its value.

1 star effect
Star also known as color effects or graphics effects. Convex curved crystal in the light irradiation, showing the intersection of radiance, six shot, and shot up to 12 star-light optical phenomena on the surface, like the stars in the sky.

2, cat's eye effect
Crystal arc when exposed to light, the crystal surface display of the bright band of light, rotating crystal, the light with movement, like cat’s eyes.

3. color effect
Crystal in the sunlight or lighting (rich red light) under various light sources, showing different colors, called the crystal color or color effect.

4, moonlight effect
Moonstone is lattice-like double-crystal feldspar, two groups of similar twin vertical lines on the incident light scattering, intensive light scattering together, showed a hazy halo color, like the moon, and so called moonlight effect.
