Jewelry item
A jewelry item includes an inner ring base, an inner ring arranged on the inner ring base, and a decorative body. A slot is provided on an outer surface of the inner ring base. The inner ring defines a through hole at a position corresponding to the slot. The decorative body includes a mounting column. The mounting column passes through the through hole and is limited in the slot. The decorative body is limited to the inner ring base by a triple limit locking structure, which completely prevents the decorative body and inner ring base from detaching. The limit locking structure is very simple and ingenious. The jewelry item is able to be assembled and disassembled by hands without using tools. Compared with the prior art, the jewelry item is more convenient for a user to assemble, which improves assembly time and efficiency.
