Chow Tai Fook is a famous jewelry brand, and the inheritance circle and Xiangyun craft are two different technologies. Inheriting the prime circle is one of Chow Tai Fook's classic designs, with the round prime circle as the main element, implying infinite cycle and eternal love. Xiangyun craft is a special craft used by Chow Tai Fook in design. Through carving and inlay, the image of Xiangyun is integrated into jewelry, which means auspiciousness and happiness. Although these two processes are one of the characteristics of Chow Tai Fook, they are different in design and performance.
