French Art Nouveau Bronze Sculpture by Rivere

A French Art Nouveau patinated bronze sculpture by Théodore Rivie`re, featuring two intricately-sculpted figures from the story of Carthage. The woman has emerald eyes and her crown is accented with rubies. The subject of this figural sculpture is taken from Gustave Flaubert''s novel, "Salammbô." The story takes place between 241 and 238 BC, during the war between Carthage and its mercenaries, who were in revolt. Mâthô, the Lybian rebel chief, fell in love with Salammbô, the daughter of the Carthaginian leader. This scene depicts the moment when the mortally wounded Mâthô dies at Salammbô''s feet, declaring his love for her. The figure of Salammbô, the femme fatale,also inspired other Symbolist artists.

Ostertag Paris Art Deco Diamond and Platinum Double Clip Brooch

A French Art Deco platinum double clip brooch with diamonds by Ostertag.

The clips are designed in a stylized wing motif. Signed box, ''Paris Arnold Ostertag''. The firm of Ostertag, founded in the 1920''s by Swiss-born, Arnold Ostertag (1883 – c.1940) is said to have created objects that rivaled the creations of the more celebrated houses of Cartier, Van Cleef & Arpels, and Boucheron. The Ostertag Maison was located in Paris, at number 16 Place Vendôme, near other important jewelry houses of the day. During the 1920s and 1930s, Ostertag was especially known for jewelry and objets d''art based on Asian and Indian designs. One style, known as Tutti Frutti, popular from the early 1920s to the late 1930s, combined influences from Islamic religious architecture and so-called Hindu or Indian styles. Emeralds, carved rubies, and sapphires – often imported from worldwide locations – were interspersed with diamonds. The jewels were crafted into unique pieces using the highest known techniques of the day and arranged into flowers and leaves, studded with berries and fruit. Many of the creations were purchased by an elite clientele that ranged from empresses, kings, and dukes to celebrities. Ostert ... ag was among the renowned Parisian jewelers, led by Cartier and Mauboussin, that were invited to commission masterpieces in collaboration with other respected and well-known jewelry and timepiece houses of the day. Ostertag''s objets d''art and decorative clocks made by the revered clockmaker, George Verger, are jeweled works of art. In 1929 Ostertag exhibited jewelry and objets d''art at the Musée Galliera. Ostertag''s Paris shop continued until late 1939, when he left for America, where he died around 1940. His biographers, Proddow and Healy, write that Ostertag regularly visited America in years between World Wars I and II. They write that he would come to New York in mid-October, spend two months in Los Angeles, then visit Florida, and return to Paris via Cannes at Easter. After two months in Paris, he spent July in Deauville, August in the south of France, and September in Biarritz. At the onset of World War II, Maison Ostertag closed its doors forever. Discussed in Art Deco Jewelry by Sylvie Raulet, Rizzoli, 1985.

Gemological Institute of America certificate #2171449596 states the pearls are natural saltwater button pearls. The multi-generational New York firm of Marcus & Co was founded by an ambitious young German immigrant who had trained at a prominent Dresden court jeweler. In 1892, after working with Charles Lewis Tiffany, Hermann Marcus and his sons William and George together set up a business that soon became a glittering New York society institution renowned not only for its superb diamonds, colored stones and pearls, but also its instantly recognizable, original design style. The firm produced great jewels in the Art Nouveau and Arts & Crafts sensibility, with George, the artist/designer, drawing inspiration from sources as diverse and exotic as the contemporary French masters, the Moghuls and Maharajahs, the garland style of the Ancien Regime, and the genius of Renaissance goldsmiths. George''s distinctive, confident hand was always discernible in Marcus creations. Working as a team with George, his brother William was a gem and pearl connoisseur who travelled the world hunting fine gem material, including purchasing the entire production of never-before-se ... en black opal in Lightning Ridge Australia in 1908. Marcus exhibited at the 1900 Exposition Universelle in Paris, and their work won prizes at the prestigious Society of Arts & Crafts of Boston. Plique-a-jour enamel was an art in which Marcus & Co. excelled, creating jewels with unprecedented three-dimensional depth in this medium. The firm and family were well-known for their charitable activities and promotion of young jewelers such as Raymond Yard.

Tiffany Glass and Bronze "Dragonfly" Chandelier

A Tiffany Studios New York "Dragonfly" glass and bronze chandelier. This elegant chandelier is composed of a choice selection of glass, which makes this an exceptional example of Tiffany''s iconic dragonfly lamp. The dragonflies are composed of dark green glass bodies, variegated blue glass wings and red glass eyes. The cabochon glass jewels that surround this chandelier depict emeralds, sapphires and topaz. The two top and three bottom borders are made up of various colors of rippled glass. This exciting glass composition rests upon a ground of green, green/blue and brown glass. While Tiffany was largely credited for his company''s glass innovations during his lifetime, recent archival research has shed light on the unsung heroes behind his genius. Two such figures were responsible for the astounding effects of this dragonfly lamp: Tiffany had gone through four chemists before he landed on Arthur J Nash, a chemist previously employed at the White House Glass Works in Stourbridge. England. It was Nash''s formulas, developed from before his employment at Tiffany, that became the core of Tiffany''s palette. Nash was no stranger to experimentation, adding unconventional materials such as birch bark and burnt oats to create his amber glass. Clara Driscoll, head of the Tiffany Studios Women''s Glass Cutting Department, designed the dragonfly lamp, earning much acclaim for h ... er artistic prowess in her time. (For more information on her work see "A New Light on Tiffany: Clara Driscoll and the Tiffany Girls," by Martine Eidelberg, Nina Gray, and Margaret K. Hofer, 2007.) Louis Comfort Tiffany''s "Dragonfly" lamps have become so iconic and loved because the artisans who made them were not limited in color as they were when making floral and geometric shades. We can imagine that the dragonflies that adorn the lower edge of the shade are flying low across a verdant field. Similar chandeliers are pictured in: "Tiffany Lamps and Metalware: An illustrated reference to over 2000 models," by Alastair Duncan, Woodbridge: Suffolk: Antique Collectors'' Club, 1988, p. 230, plate 891-893.

The panther has since inspired timeless and elegant collections of jewelry and timepieces that show the multiple facets of the animal that can be at times bold, regal or sensual." -- Amazing Cartier, by Nadine Coleno, Flammarion, 2008, p. 72

Gold Ring with Diamonds and Emeralds by Marchak

A French Mid-20th Century 18 karat gold ring with diamonds and emeralds by Marchak.

The leaves center on 4 oval cabochon emeralds with an approximate total weight of 20.20 carats. Ring size 6-1/2. With original drawing. Born in 1854 in a poverty-stricken area of Kiev, Joseph Marchak sold his own clothing at age 10 to pay the fees associated with becoming a jeweler''s apprentice. Fourteen years after beginning that apprenticeship, Marchak used the dowry from his young bride to open his own small shop in the neighborhood in which he was born. Within a year, he had upgraded to a full maison on the Kreshchatyk, Kiev''s main street of luxury retail. Marchak quickly drew the attention of Tsar Nicholas II, who traveled to Kiev to have Marchak design gifts to be given to his family celebrating the 300th anniversary of the Romanov dynasty. Seemingly overnight, Marchak had become the most highly sought-after and highly celebrated luxury maker in Russia, easily rivaling even Fabergé. But Marchak was also widely recognized abroad, winning a prestigious medal at the World''s Fair in Chicago in 1893, and another in Antwerp in 1894. Dubbed the "Cartier of Kiev," Marchak, his family and his workshop fled Russia at the outset of World War I and ... landed in Paris, where they established another successful workshop and storefront on the Rue de la Paix. The Marchak family continued to make exquisite and highly stylized treasure that defied commonplace trends well through the mid 20th Century.

Trabert & Hoeffer Mauboussin Art Deco Yellow Diamond, Emerald and Platinum Ring

An American Art Moderne diamond, emerald and platinum twinstone ring by Trabert & Hoeffer-Mauboussin. The stepped, high-arched mount set with a yellow cushion-cut diamond weighing approximately 1.75 carats, and an emerald-cut emerald weighing approximately1.65 carats, completed by stepped shoulders and shank of conforming design. Formed in 1935, Trabert Hoeffer-Mauboussin was a merger between Mauboussin Paris'' Park Avenue branch and an innovative American firm, Trabert & Hoeffer, a Manhattan partnership whose stylish owners had Hollywood connections and a tendency to splurge on world-famous gems for display. Howard Hoeffer, a proponent of French jewelry design who sent his artisans to Paris for training, had cultivated Georges Mauboussin from the early 1920''s, even before the French firm won a Grand Prize at the Grand Central Palace Exhibition in 1924. By the mid 1930s, the Depression had brought both firms to the brink of bankruptcy, struggling with large inventories of superb jewelry and gems of historic provenance. From 1935 to 1940, the firms collaborated to produce and loan high style jewels and large gems to the Hollywood studios. The period''s iconic photo portraits of Marlene Dietrich and Claudette Colbert, among others, show these eternal stars adorned in the firm''s stunning Art Moderne masterpieces. A product of that early collaboration, this twin stone pla ... tinum ring, with its classic pairing of emerald and yellow diamond, is a mini-masterpiece of Machine Age design and construction. Dense, streamlined, and perfectly balanced, it is a chic statement of French-American style.

Victorian Gold Snake Bangle with Diamond, Sapphire and Ruby

An English Victorian 18 karat gold hinged snake bangle with diamond, sapphire and ruby. The head is a cabochon blue sapphire that has the approximate weight of .15 carat surrounded by .12 carat of rose-cut diamonds with 2 cabochon ruby eyes that have the approximate total weight of .04 carat.

This bracelet, which could alternatively be worn as an arm band, depending on the preference and comfort of the wearer, is a particularly charming example of Victorian snake jewelry. Unusually, the serpent''s tail fully encircles the bangle several times as the two ends of the bangle meet, adding fantastically to its visual width. The diamond-haloed sapphire crowning the piece adds a beautiful bit of color and brilliance, as do the ruby eyes.
