There are many methods for identifying jewellery on Saturday, but visual identification is the easiest, economical and practical method. It is a traditional method and a method for people in the jewelry industry in China. It can also be used by general investors.

Opal stone is like a colorful flower tube, and moonstone is reflected like the light of the moon. Some artificial gemstones are difficult to do, and some of the deliberately created brilliance lines are often too clear and give people a false feeling. Light flexibility is also poor.

Through the above several methods, how much can be used to identify the true and false of the moon blessing jewelry.
