The Martele .9584 OKE mark is found on one-of-a-kind silver pieces from Gorham’s Martele line, the company’s most prestigious collection of hand-wrought Art Nouveau silver. The “.9584” indicates the silver purity—95.84% pure silver, even higher than sterling (92.5%)—a standard unique to Martele, showcasing Gorham’s commitment to exceptional quality. The initials OKE refer to the specific silversmith, designer, or chaser responsible for the piece, as each Martele item was individually crafted and signed. This mark confirms the piece's authenticity, extraordinary craftsmanship, and place within one of the most luxurious and collectible American silver lines.
