Four-leaf clover refers to Van Cleef & Arpels, a famous French jewelry brand. After its appearance in 1968, the four-leaf clover quickly became the brand symbol of Van Cleef & Arpels. For fifty years, this lucky and charming pattern has been deeply loved by women.
We often see jewelry products in gold shops or other jewelry stores that look like four-leaf clovers, some of which are enlarged or reduced in proportion, while others are made in a ratio of 1: 1. In fact, this is not an infringement, because the shape of jewelry does not have the obvious characteristics as a trademark.
