Evaluating the value of crystal mainly depends on four aspects:

One: quantity. The less the quantity, the better. Colorless I love e-commerce network-there are more crystals and smoke crystals, and I love e-commerce network with yellow water-

There are fewer crystals and amethysts, and fewer crystals with hairs and inclusions. Two: clarity: the purer the crystal ball and jewelry, the better. You need a bag to decorate the crystal.

Body 3: Body: integrity, image, bright colors and clear meaning are the top grades.

Four: technology: modeling needs proportional coordination,

Clear priorities, vivid images, bright polishing requirements, no scratches.
