Jewelry stores can only check the sales and purchase records in the past three years. Take Chow Tai Fook as an example. You can check the purchase record by reporting the card number in the physical store.

Jewelry in economic trade and commercial sales is a kind of special commodity with double special effects of commodity and art, and its artistry is reflected in color, light and form, while commodity is reflected in value, spirit and righteousness. That is to say, jewelry can not only show the commodity sales value of productive labor, but also show the religious mystery of ideology, and at the same time show the strong commemorative significance of good wishes. Second, jewelry can also show power, status and wealth.
