Off-beat and irreverent designs were Verdura's hallmark and enduring legacy. Verdura was an exceptional visual artist, and his drawings were remarkably accurate and detailed. At times, he seems to have been influenced by Faberge, but he also broke with American design standards to set entirely new trends. For example, he was one of the first designers to make it fashionable for diamonds to be worn both during the day and evening. He is also known as one of the first major designers of the 20th century to set colored stones in yellow gold, at a time when diamonds set in platinum was the safe choice. "You can never trust diamonds," he often said. The result was many exceptional designs, such as a series of brooches made of seashells, encrusted with precious stones. Other enduring influences were Greek mythology, Christian iconography, medieval themes and most notably Byzantine patterns, which resulted in his famous Maltese cross cuffs.
