If the diamond ring and other jewelry belong to the wedding ring that the man or his parents bought and gave to the woman before marriage, it should be regarded as the woman's personal property and should not be returned. Jewelry purchased after marriage is only for the wife's own use, and should be recognized as the wife's exclusive daily necessities and owned by her. To take a step back, even if the diamond ring is not recognized as his wife's personal daily necessities, the act of giving jewelry to his wife by her husband should be regarded as a separate gift to her husband, which is legal and effective. Therefore, jewelry does not belong to the common property of husband and wife, but should be regarded as the wife's personal property and belongs to the woman.
