An outstanding 18K gold pendant set with an amazing enameled alpine scene by Carlo Poluzzi (1899-1978), the greatest Swiss enamellist of the the 20th century. Poluzzi sometimes used the very difficult technique of applying translucent enamel over an engraved gold plate to produce brilliant sunrise or set effects as seen in the left side of the sky in this example. This required multiple coats of different colored enamels which increased the likelihood of unwanted cracks during the multiple firings. Poluzzi was perhaps the only enamellist capable of this technique in the 20th century, and indeed, the scene is signed at the lower left. Of course, this example is also signed at the lower left. In the 1920s, Poluzzi (still in his low 20s) became the master of Emaux de Genève, the provider of the highest quality enameled dials and cases for luxury horlogers such as Vacheron & Constantin, Patek Philippe, Rolex and Gubelin. This plaque is set as a pendant by the Gubelin. The Holbein-style setting features square cut rubies and emeralds amid swirling gold foliage. The gemstones are of very fine quality with intense, saturated coloring and excellent clarity. The reverse is stamped with Gubelin’s hallmark and the Swiss gold mark for 18K.

A very fine pair of Art Deco cufflinks, the front faces comprising carved natural green jadeite discs edged in black enamel. The jade plaques, with bright grass green coloring with moderate mottling and translucency, are carved in a traditional stylized floral motif. The faces are connected to yellow gold backs engraved with concentric rings in a target pattern. The front and back faces are constructed with identical structural elements, so they are entirely original. The faces are joined with clips so a face can be removed when fitting into a cuff hole. The faces and connectors are stamped with French 18K gold marks and with an illegible master goldsmith’s mark.

A fine green-toned cat's eye chrysoberyl cabochon surrounded by delicate scalloped border set with seed pearls centers this Victorian stickpin conversion ring.

A lovely silver, plique-a-jour enamel, mother-of-pearl, and paste pendant in the German Art Jugendstil or Nouveau taste. The pendant is worked with very attractive enameled cells in shades of teal, cream and rose. German Art Nouveau pieces from the Pforzheim school tend to be more linear and symmetrical than those from France, and this piece is a classic example. The use of a collet-set mother-of-pearl oval is the center position is very typical of the work of Otto Prutscher, the leading German Art Nouveau jewelry designer. The back is marked "Depose 900" and is signed "HS" or "SH".

Origin: Germany, ca. 1900. Condition: appears to be converted from a brooch; no enamel damage. Size: 1-1/8" x 1"; chain 16-1/2" long. Weight: 6.3 gr.

A very rare pair of 18K yellow gold cufflinks designed by Soren Georg Jensen for the firm founded by his father, Georg Jensen. Designed in 1962, during his first year as the firm's artistic director, these cufflinks are a clear example of the stripped-down, modernist sculptural direction the younger Jensen wanted to pursue. Jensen's gold jewelry is considerably rarer than silver, and was often retailed by Jensen at ten times the price of the same design in silver. The cufflinks are appropriately hallmarked and have the design number "1091".

Origin: Denmark, ca. 1965. Condition: excellent, no monogram. Size: 11/16" diameter. Weight: 17.4 grams.

A glamorous pair of drop earrings in a formal Georgian style set with rose cut diamonds and richly colored pear-shaped rhodolite garnets. The gems are set in silver-topped 12K gold to heighten the color of the diamonds, in the manner of period Georgian jewels.

• Weight: 8.2 grams.
• Approximate Total Gemstone Weight: diamond, .62 carat; rhodolite garnet, 1.4 carats.

An extremely rare pair of 18th century silver double-faced cufflinks set with old European cut colorless paste gemstones. The crystals are held in place in traditional cut-down settings typical of the period and the faces are joined with the quatrefoil connector almost always seen on this type of cufflink. The backs of the crystals are foiled in silver to provider a brighter appearance. Cufflinks such as these are usually broken up into two pairs of earrings, so it is quite uncommon to find a pair in original condition.

Origin: England, ca. 1780. Condition: excellent, original patina. Size: 17/32” diameter.

A stunning pair of lage Georgian or early Victorian transitional earrings worked in 18K gold and silver. The earrings, each in form of a convolvulus (morning glory) blossom feature a variety of antique cut diamonds, mostly cushion and mine cuts. The smallest stones are rose cuts. The diamonds are of excellent quality, mostly eye clean and with superb, warm sparkle as the earrings dangle freely. The expert craftsmanship that allowed the diamonds to be set very close together with little metal showing gives the earrings a dramatic appearance when being worn. Most of the diamonds are set “a jour” (open to the light at the back), but the largest center diamonds in the rosettes at the top of each earring are set in cut-down mountings which suggests the earrings were made in the transitional period between the Georgian and Victorian eras. The backs of the rosettes have a layer of 18K gold so the silver wouldn't tarnish the wearer's earlobes. The wires are 18K gold and are probably replacements of the originals.

• Origin: likely English or possibly French, ca 1830-40
• Condition: excellent
• Dimensions: 1-1/2” x 11/16”
• Approximate Total Diamond Weight: 6.16 carats
• Weight: 8.8 grams

A fine example of a French-Flemish croix papillon (butterfly cross) from the northern region of France around Calais. Jewelry scholars believe these were actually made in Belgium (a French region at the time) where they were known as “croix à la Jeannette” (Jeanette crosses). They were popular across the French regions of Picardie and Pas-de-Calais and into Normandie. This example retains all three of its original parts, each worked in gold and silver and set with table cut diamonds. Croix papillon in original condition are somewhat uncommon as they were often separated into multiple components to satisfy inheritance among multiple daughters. The filigree work is very finely done. The upper portion retains its original pair of slides, as these crosses were traditionally worn high from a wide ribbon tied around the neck. At some point, likely in the later 19th century, a pin stem and c-clasp were added for wear as a brooch. Today, the cross can be worn as a brooch or as a pendant suspended from a chain using the slides. There is a partial hallmark with the guarantee stamp “D” suggesting the cross was assayed at Liège.

• Origin: France/Belgium, ca. 1790-1820
• Condition: excellent, all parts intact
• Dimensions: 1-15/16” x 3”
• Weight: 13.2 grams

A rare gilt bronze watch fob with a carnelian seal with an allegorical figure depicting "Temptation" in the form a hooded monk with hands piously folded across his own chest while standing next to a nude woman. The woman is pressing against him and appears to be whispering into his ear. Virtuous themes presented gentlemen of the era with an opportunity to indulge in a little erotic naughtiness. The figure is enhanced with detailed engraving.

• England or France, circa 1830
• Very good condition; light wear to gilding; no engraving on carnelian; better in person than the photos
• 1-1/2" x 7/8" x 11/16"

A nice Georgian locket in the form of a Maltese cross with a central rock crystal locket compartment. The arms of the cross are made from faceted carnelian plaques mounted in gold around the central compartment. The compartment was intended to hold the woven hair or perhaps a miniature portrait of a loved one. The Cross of the Knights Hospitallers of St. John was created in 1126 based on designs from the Crusades. The eight points of the arms represented truth, faith, repentance, humility, justice, mercy, sincerity and endurance. During the latter Georgian era, romantic notions of history caused the Maltese cross to become a very popular fashion accessory. Tested and guaranteed 12K.

• Origin: England, ca. 1800.
• Condition: excellent; no damage to gold mountings or carnelian; the cross retains its original fluted gold bail; a small (1/32”) flake to one corner of a rock crystal cover.
• Dimensions: 1-7/16” x 1-7/16” (excluding bail).
• Weight: 9.0 grams.

A marvelous Georgian cross pendant worked entirely in seed pearls and centering an oval cut citrine in a 9K gold push-up setting. Seed pearl jewelry became popular during the last quarter of the 18th century and remained in fashion for about fifty years. The forms were cut from pieces of mother-of-pearl then drilled with tiny holes. Strands of horsehair, bleached to become white and translucent, were used to sew hundreds of tiny natural seed pearls to the form. The center citrine adds a bit a sparkle to what would otherwise be a very chaste piece. Some of the pearls in this piece are quite large for seed pearl jewelry. Although pearls are associated with purity, crosses are difficult to find in seed pearl jewelry. The 14K gold bale is recent.

Origin: England, ca. 1775. Condition: excellent, some glue reinforcement of the horsehair in places on the back. Size: 2” x 1-3/8”.

A lovely Georgian mourning pin worked in 9K yellow gold, the center crystal-covered compartment bordered in faceted jet. Lighter-colored hair is somewhat less common that dark hair, and it contrasts particularly nicely with the black border. The reverse is engraved "Wm Dumelow/ob. 16 Mar/1811 At 42." Tested and guaranteed 9K.

Origin: England, 1811. Condition: excellent, all original. Dimensions: 1" x 9/16". Weight: 3.3 grams.
