Crystal ball and glass ball identification The jewelry market is worthy of the crystal treasures and exquisite products. Crystals are glass products.

Just use a piece of hair on a white paper,

It is found that the hair double image is a crystal ball, and if the hair double image is not visible in any direction of the scroll, it is a glass ball. This is because crystals have birefringence and glass long and short crystals have only refraction.
