Antique Diamond, Gold and Silver Maltese Cross Brooch

The brooch has 130 old European-cut and old mine-cut diamonds with an approximate total weight of 18.00 carats including the center old European-cut diamond weighing approximately 2.25 carats. Fold down bale. Antique box. The Maltese cross, in Italy also known as the Amalfi cross, is the cross symbol associated with the Knights Hospitaller (the Knights of Malta) and, by extension, with the island of Malta. The cross is eight-pointed and has the form of four "V"-shaped elements, each joining the others at its vertex, leaving the other two tips spread outward symmetrically. Its design is based on crosses used since the First Crusade. The 15th Century Crusaders adopted the Cross of Malta as their insignia because its eight points represented the eight Beatitudes prescribed in the Sermon on the Mount. Those, in effect, declare (1) blessed are the poor in spirit, (2) the meek, (3) the pure, (4) the merciful, and (5) the peacemakers; (6) blessed are they that mourn, and (7) seek righteousness, and (8) blessed are they who are persecuted for righteousness sake. The Cross of Malta had a religious origin but the Knights of St. John also made it their battle standard for the liberation of all men, women and children who suffered oppression. The ideals for which the original Crusaders fought parallel the principles of democracy today, freedom and justice.

Victorian Diamond and Turquoise Snake Bangle Bracelet

A Victorian 15 karat gold bracelet with turquoise and diamonds. This is a large bangle, to be worn either on the wrist or as an arm band, It has the form of a serpent dynamically wrapped upon itself and seemingly caught in motion, covered in tightly-set cabochons of turquoise and replete with striated gold on the reverse side to complete the appearance of a snake. The head of the reptile features a large tear drop-shaped cabochon of turquoise framed by twelve old mine-cut diamonds that have approximate total weight of 1.14 carats, and has a lovely pair of diamond eyes. Turquoise was mistakenly named as such during the Victorian times because it was believed by most Western Europeans that the blue stone came from Turkey, when in fact it merely passed through Turkey on its way westward from Iran. Because of its color, turquoise was associated by Britons in the Victorian Age with the Forget Me Not flower, which, in the very sophisticated and well known "language of flowers," was a symbol of undying love. The snake, when depicted in a continuous loop, was also understood during this period as a potent emblem for eternal affection, largely due to the fact that Prince Albert presented Queen Victoria with a snake band with a gemstone head as a wedding ring.

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. After Prince Albert gave Queen Victoria a snake band with an emerald head as a wedding present in 1839, snakes, particularly in a fully realized or continuous band form, came to be a symbol for eternal love and devotion to the Victorians. 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.

Marcus & Co. Art Nouveau Opal and Gold Stick Pin

An American Art Nouveau 18 karat gold stick pin with enameling and black opal by Marcus & Co. The stick pin has a cabochon opal surrounded with four enamel side sections decorated with gold relief arabesque designs. 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-seen 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.

Art Nouveau Brooch with Aquamarine, Diamond and plique-à-jour Enamel by Lalique

"L''Anémone des Bois", A French Art Nouveau masterwork by René Lalique. Created in 1897, this 18 karat gold brooch showcases Lalique''s mastery of "plique-à-jour" enamel and also represents one of his earliest explorations of the art of molded glass. The brooch is accented by two oval faceted aquamarines weighing approximately 8.10 and 3.75 carats. More than any technical mastery or gemological import, the brooch is distinguished by its aesthetics and its deep meaning. This exquisite "Anémones des Bois" Brooch is an important example of René Lalique''s early work, predating his international debut at the Exposition Universelle of 1900. While his most prolific version of the anemone motif was the "Anémone couronnée" or poppy anemone, only a few choice pieces depict the "Anémone des Bois" or wood anemone. Unlike the poppy anemone, which grew in the balmy Mediterranean summer, the Anémone des Bois was known to the French as the harbinger of spring. While the forest floor lay dormant, the wood anemone alone reared its small head. Areas where the poor could pick this humble flower were demarcated with signs reading "Les Halles." The Anémone des Bois lined the border of the forest, enticing promenading couples into the forest''s embrace for an afternoon tryst. Pure white anemones thus became a symbol of virginal purity, mourning its imminent profanity by carnal desire. Lalique ... knew these traditions well from spending his childhood and summer holidays in the commune of Aÿ in Marne, located on a plateau overlooking the hillsides of Champagne. Two forests dominated the Marne landscape. To the west lay the old-growth forest of Sermiers, and to the east lay La forêt domaniale du Chêne à la Vierge. Promenading in the forest was a popular Sunday pastime for locals, especially as a way to escape the unrelenting dry heat of the noonday sun. Lalique expanded upon the theme of carnal desire, using the anemone to allegorize the stages of courtship. Our Anémone des Bois marked the beginning of this five-year-long exploration. With its petals slightly closed, the flower embodies the initial "rejet" or rejection of love. Fitting of a depiction of "rejet" the work epitomizes divine symmetry and youthful vigor. The flower''s posture relates to local wisdom: villagers could tell rain was coming when the Anémone des Bois closed its petals. By closing its petals, the flower rebuffs the words and sexual advances of the man. The second anemone in the series has its petals in disarray but receptive to potential pollination. An anemone in this position embodied "l''acceptation de l''amour" or the acceptance of love. The third anemone is the most sensual of the series, two anemones approach a passionate kiss, embodying the "consommation" or consummation. The final anemone in the series was completed in 1901. Titled "Mort de l''anémone" it is Lalique''s only representation of the blue anemone. Through the consummation, its petals have been dyed and its purity defiled. In macabre detail, the skeletal structure of the anemone''s rhizomes, or underground stems, are put on full view. The plant has been uprooted, and the encounter has finished. Contemporary novelist Émile Pouvillon related the death of the anemone to the act of deflowering in his 1895 short story "Les Anémones sont Mortes." The story''s heroine, a young country girl, loses herself in a bout of unrestrained euphoria with her lover. In their rolling about, "Anémones des Bois" are ripped out and bruised. At the 1898 Salon, the first Anémone des Bois was a critical triumph. Displayed with the second and third anemone in the series, the first was favored for its fully articulated plique-à-jour leaves. In the premier French decorative arts magazine Art et Décoration, the Anémone des Bois was praised for its "candid whiteness" and leaves that suggest "an infinitely complicated and precious architecture." Our Anémone des Bois is resplendent with the technical acuity that made Lalique known as the "master of modern bijoux (jewelry.)" In his early years, Lalique personally designed and modeled each mold for his creations in clay. These molds were then cast in iron and coated with a paste of resin and beeswax, hand-tooled for detail. The finish pressed-glass jewel was submerged in a bath of hydrofluoric acid, frosting the exterior. A thin layer of "jade green" powdered enamel was sifted and annealed onto the piece. The venation of each petal was painstakingly cut, revealing the plain crystal underneath. The warm glow of the gold backing gives the piece a breathtaking amber hue.

An aristocratic clientele was soon to follow him to his new workshop. A reputation as the "jeweler of the tiara" was earned in those early commissions when Nitot created the coronation crown for Napoleon.

Empress Josephine appeared at the coronation resplendent in a tiara created for her by Nitot, and so it began.

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.

An Art Deco platinum necklace with turquoise, rock crystal, chalcedony and diamonds by Mauboussin. There are 72 round-cut diamonds that have the approximate total weight of 5.96 carats. The house of Mauboussin was considered the leader in design innovation and luxury creation in the Art Deco period, so much so that Maurice Dauzalle, the famed art critic, wrote of the firm''s 1930 exhibition in "L''Illustration:" ''All the creations on display radiate the same artistic brilliance, the influence of a strong personality, a decisiveness.... In all of [Georges Mauboussin]''s work there is a lively intelligence, a driving inspiration....'' This striking collar features a strong, solidly Deco design that, unusually, centers on the cool interplay of color provided by the evenly-matched turquoise and the deeply black onyx. Interspersed with sleek slivers of architecturally-striated rock crystal and diamond-studded platinum accents, this industrially elegant piece demonstrates the height of design from the well-celebrated house of Mauboussin. With certificate of authenticity from Mauboussin.

A Pair of Multi-Gemstone Brooches by Rene Boivin

A set of two of French Art Deco 18 karat gold "lilac-leaf" clip brooches,the larger set with oval-cut green tourmalines, yellow heliodor beryls, yellow-gray beryls and aquamarines, highlighted by a single-cut diamond stem set in platinum, the second set with circular and oval-cut pink tourmalines, pale amethysts, and green tourmalines, both with medium-relief naturalistic modeling, by René Boivin. Executed under the leadership of famed Boivin designer Juliette Moutard, these spectacular pieces are as significant in the history of high jewelry as they are beautiful. These elegant brooches demonstrate the height of Moutard''s particular style: the refined, geometrically-rendered organic shape of the lilac leaf, the sensitive and masterful employment of color gradation, and the interplay of complementary shapes are all hallmarks of Moutard''s work for Boivin. The brooches have oval-cut tourmalines, green and yellow beryl, which together have and approximate total weight of 42.25 carats; aquamarines with an approximate total weight of 17.00 carats; and 30 single-cut diamonds with an approximate total weight of .70 carat. With authenticity report from expert Francoise Cailles. Boivin''s work is a remarkable exception to many of the presiding trends of the 1930s. For one, the house eschewed the stark, monotonous, and highly geometric Art Deco stye. While other firms continued ... to churn out architecturally clean designs in diamond and platinum, Boivin maintained their commitment to celebrating color and the organic forms of the natural world. Also notable, and unusual for the time, is that Boivin was an all-female led firm. After the premature death of René Boivin in 1917, the firm would be led until its dissolution by his widow, Jeanne Boivin, and a host of brilliant female designers, among them Suzanne Belperron, Juliette Moutard and Germaine Boivin,

Art Nouveau Necklace with Opal Scarab by Antoine Bricteux

A French Egyptian Revival 18 karat gold pendant necklace with boulder opal, diamond, freshwater pearl and enamel by Antoine Bricteux, Paris.

Note: Exquisitely modeled and finished, this Egyptian Revival winged scarab necklace by Maison Bricteux, Paris, exemplifies the total freedom of imagination that characterized the Art Nouveau period. Centering a scarab carved from a boulder opal still in its seam of ironstone, within a surround of translucent plique-a-jour enamel feathers, the jewel demonstrates Art Nouveau''s restless exploration of unusual techniques and materials. The jeweler Antoine Bricteux ran a small boutique firm in the neighborhood of the Palais Royale, a center of the artistic luxury trade in Paris. Mention of his work appears in Henri Vever''s history of French jewelry, where Maison Bricteux is described as a "distinguished firm" which created "charming jewelry of modern inspiration." Bricteux collaborated with the designer G. Landois -along with the great firm ... of Louis Aucoc -until Landois'' sudden death. Egyptian motifs such as the scarab have appeared prominently in European art since the Renaissance. Worn over the millennia in many societies as a favorite amulet, the scarab is identified with purity of heart. During the Art Nouveau period, it was a highly popular design motif along with winged women, who represented the imaginative liberty of the age.

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.

Estate Aquamarine, Sapphire, Diamond and Gold Earrings

A pair of American Estate 18 karat yellow and white gold earrings with aquamarines, sapphires and diamonds by Zwikker & Zacher.

Detachable drops. With original box. Beloved as the birthstone for the month of March, the name aquamarine is derived from the Latin word for sea water. Known and treasured since before modern times, the 1st Century A.D. historian and philosopher Pliny the Elder wrote of the stone, "the lovely aquamarine, which seems to have come from some mermaid''s treasure house, in the depths of a summer sea, has charms not to be denied." Roman legend had it that the stone absorbed and preserved young love, and was the most popular stone for marriage and morning gifts. (A morning gift is an object presented to the bride by her groom the morning after their wedding.) In fact, this custom may well be the origin of the "something blue" that is traditionally presented to a bride before her nuptials. The stone was also believed to protect travelers, particularly sailors, and is often associated with the far-traveling St. Thomas the Apostle. From ancient through Medieval times aquamarine was the preferred stone for the making of fortune-tell ... ing crystal balls for its supposed "divining power," and similarly used as an antidote to eye illnesses for the same reason. This particular piece exemplifies the beauty of blue aquamarine, especially with its stunning blue sapphire and diamond accents.

The Catholic church adopted the sapphire as the ecclesiastical stone of choice in the 12th Century, and royalty from King Solomon to Prince Charles have employed the stone in the making of rings of great significance. The Sinhalese of Sri Lanka, where this particular stone originates, believed sapphires had talismanic properties.

The present sale offers the entire stock of this distinguished firm. All pieces are original designs of Marianne Ostier, co-founder with her late husband of the firm and an internationally famed designer of jewelry. "Of the decision to close the business, Marianne Ostier said: With the passing of my husband, I have had to devote more and more of my efforts to administrative duties. These demands of my time can no longer be met without artistic compromise which to me is unacceptable. "Representing the third generation of court jewelers in Austria, Oliver Ostier came to America following the Anschluss of 1938. Shortly thereafter he founded the firm of Ostier, Inc., with his wife Marianne, a talented painter and sculptress as well as an artist in the design of jewelry. Author of Jewels and the woman , the ... basic primer of the art of wearing jewelry, Marianne Ostier''s designs became major jewelry fashions and classics of modern designed jewelry. She is responsible for numerous innovations, such as the pincushion clip, the famed skin pin and free-form jewelry; she pioneered in abstract designs for jewelry and, as a sculptress, brought a new dimension to her work in jewelry design. For many years, Mrs. Ostier won the Diamond U.S.A. Award and the Diamond International Award for design excellence. The first life-time member elected to the Diamonds-International Academy, the hall of fame for modern jewelry designers, she represented the United States at the Art in Precious Jewelry exhibition at the Finch College Museum of Art in 1966, which featured the work of the foremost designers of ten countries. Among the artists, in addition to Mrs. Ostier, were Georges Braques and Salvador Dali."
