Robert DeMario’s jewelry is multilayered and unique in the combinations of materials and techniques he employed. Natural wood, intricate details in mother of pearl, innovative techniques using gold foil, rock crystal and beads gave his work a glamour and boldness that makes his pieces highly desirable still.

If you are looking for vintage Robert DeMario jewelry, you have come to the right place. In this article you will learn about the history, designers, marks, materials, and tips on how to buy.

Brief History of Robert DeMario Jewelry

Robert DeMario was a successful designer of costume jewelry in the 1940s-1960s. What jewelry historians cannot agree on is whether or not he started out designing for Miriam Haskell. At first glance, some of Robert’s beadwork and pearl designs look much like he may have learned them under Haskell’s tutelage. But there is no actual evidence. We do not know much at all about Robert’s life except that he started his career working for other jewelry designers—be it Haskell or any of the myriad others. Of that we are sure. In 1945, he went out on his own and opened Robert DeMario Jewelry, Inc. in New York City.

DeMario Jewelry includes necklaces, necklace parures, brooches and pins, though Robert is primarily known for his necklaces, bold works of art with unique clusters of glass beads, faux pearls, and rhinestones wired onto a base of gilt filigree. (Gilt is a thin coating of fine gold leaf or powder applied to a surface such as metal filigree.)

Robert’s beautifully designed and meticulously crafted jewelry arrived on the scene at exactly the right time. In the 1950s, after the restraints imposed during the war years, costume jewelry offered ladies of all socio-economic strata the ability to luxuriously accessorize the more feminine fashions that had come into style. Also, in an age that glorified mass production, Robert was one of the few jewelers who held fast to traditional methods by hand making or hand finishing the pieces that he produced in limited editions.  

Robert closed his business in 1965. The comparatively brief production period (1945-1965) and his preference for limited editions make his jewelry rarer today than that of some of his contemporaries and, therefore, in demand among collectors and expensive.

Robert DeMario Jewelry Designers

Robert designed his own jewelry, as far as we know, with one exception and for a brief period of time, Stanley Hagler (who also may or may not have worked for Haskell), an established designer with socialites and celebrities as clients. He and Stanley, planning on going into a partnership in the 1960s, collaborated on a few pieces, but those plans fell through. At one point, Stanley was a guest designer for Robert and Robert was for Stanley.

  • Faux Pearl Parure (Necklace, Bracelet and Earrings)

It’s quite a coup to find a full parure DeMario in excellent condition. More so when it is as glamorous as this one that retains a freshness that speaks of springtime and youth. The elaborate design includes gold-tone leaves surrounded by pearls and multi-colored rhinestones. The choker necklace has a 4 ½- inch extension chain. The large earrings are an additional rarity; Robert usually kept to button earrings.

The lush green glass beads against faux pearls, rhinestones and gold gilt leaves mounted on filigree is a unique and stunning brooch. The earrings are complimentary with smaller beads and gold-tone woven edge.

Tips for Buying Vintage Robert DeMario Jewelry

  • With the rarity of Robert’s jewelry, it can be tempting to grab up whatever piece you find. Do not succumb, because some of his pieces have not held up well. If you see green corrosion (verdigris) on the metal, it is irreversible. You may be able to clean off the green, but there will be black underneath.
  • As with any antiques, the appreciation of vintage jewelry depends on availability, region and the economic climate. It is best to buy what you like rather than what you think might make a profit, because that is never a sure thing.
  • Know your vendor. If you do not know the vendor, ask around for recommendations. Check the vendor’s reviews and feedback from customers. Make sure you are clear concerning policies for returns and shipping. See our picks for the best costume jewelry shops on Etsy. 
  • Use a safe method of payment, e.g., PayPal, in case of any disputes.
