Vivid yellow diamonds are distinguished by their very deep, warm and lively jonquil yellow color. It is estimated that less than 1/10 of 1% of diamonds mined are a vivid yellow with no white traces and an even yellow color throughout. A rare few possess an astounding vivid yellow color which is almost incomparable.

Susan Abeles, Vice President Director of US Jewelry at Bonhams, says: 'Vivid yellow diamonds are distinguished by their very deep, warm and lively Jonquil yellow color. It is estimated that less than 0.1 per cent of diamonds mined are a vivid yellow color with no white traces and an even yellow color throughout. A rare few possess an astounding vivid yellow colour, which is almost incomparable.

Originating in a turn of the century Tiffany & Co. six-prong solitaire ring, this Old European Cut Fancy Vivid Yellow diamond is a rare example of 19th century cutting technology. This old fashioned cutting style, rarely found in today's market, epitomizes old world charm, brilliance and, above all, depth of color.'

The first notable lot is A Fine Ruby and Diamond Clip Brooch by Cartier, circa 1935. Extremely rare, the Cartier clip reflects the evolution of style from Art Deco to Art Moderne. Gone are the strong, flat, colorful, geometric lines as these were replaced by the more sculptural aesthetic found in jewelry of the mid-1930s.

Lot 132. A fine ruby and diamond clip brooch, Cartier, circa 1935. Estimate US$ 300,000 - 400,000 (€280,000 - 380,000). Photo: Bonhams.

The brooch is geometrically designed and centers on a beautiful marquise mixed-cut ruby, weighing 3.54 carats. The central ruby has a pavé-set frame of baguette and round brilliant-cut diamonds, further enhanced by round cabochon and sugarloaf rubies and accented with square step-cut diamond.

Estimated at US$300,000-400,000, the central ruby is accompanied by an AGL report stating that it is Classic Burmese and has no indication of heat or clarity enhancement.

This diamond and ruby brooch reflects the evolution of style; from art deco to art moderne. Gone are the strong, flat, colorful, geometric lines, as these were replaced by the more sculptural aesthetic found in jewelry of the mid-1930s. 

From 1915-1930, the Russian, Egyptian, Indian, Persian and Oriental inspirations, which had dominated jewelry, began to wane and were substituted by a diamond and single colored gemstone palette which found favor by 1935. 

These all-diamond or bicolored jeweled creations were expressed with a variety of classic and fancy cut stones – round brilliant-cut, step-cut, baguette or baton cut, hexagonal, buff top, and cabochons - were utilized instead of black onyx, coral, mother-of-pearl, jade, turquoise, enamel, faience and artifacts, which had been used previously. Also gone were the flatness of the jewels; layered gemstones, brought a fresh three dimensionality to these more modern designs - jewels became more engaging with attention to negative and positive space. 

From the mid-1930s Cartier created and sold predominantly sculptural, mono-chromatic and diamond jewelry. While gemstone preferences of sapphire, emerald, aquamarine, topaz and turquoise can be found, very few ruby examples exist. 

Cartier used gemstones of exceptional quality to create a strong dynamic for these new designs. The focal point of this ruby and diamond clip is this rare, unheated Classic Burma ruby. The seldom used marquise-cut ruby draws your eye to the center of the brooch because of its beautiful rich red color, hue and shape. Framed by negative space and outlined with pave-set and fancy-cut diamonds and sumptuous buff top rubies at the edge, this clip provides an elaborate, yet simple, showcase for an exquisite gemstone.

Susan Abeles of Bonhams Jewelry adds: 'From the mid-1930s Cartier created and sold predominantly sculptural, mono-chromatic and diamond jewelry. While gemstone preferences of sapphire, emerald, aquamarine, topaz and turquoise can be found, very few ruby examples exist.

This particular clip brooch provides an elaborate, yet simple, showcase for an exquisite gemstone. The brooch is a real collector's item given the Cartier name, the era and the composition. Any connoisseur would want to have this rare jewel as their own.'

Original Blue Book Tiffany Lily Of The Valley brooch comes to auction

Perfectly timed for spring is A Diamond and Enamel 'Lily Of The Valley' Brooch designed by Donald Claflin for Tiffany & Co. Dated 1969, this Lily of the Valley brooch is the original prototype for the 1969 Tiffany & Company Blue book brooch. The inspiration for this brooch comes from the French custom of giving Lily of the Valleys on the first of May to celebrate spring and as a porte-bonheur or good luck charm. Estimated at US$5,000 - 7,000, the brooch is composed of eleven en tremblant lilies, set with round brilliant-cut diamonds, to a gold stem with green enamel leaves.

Lot 72. A diamond and enamel "Lily of the Valley" brooch, Donald Claflin for Tiffany & Co., circa 1969Estimate US$ 5,000 - 7,000 (€4,700 - 6,600). Photo: Bonhams.

composed of eleven en tremblant lilies, set with round brilliant-cut diamonds, to a gold stem with green enamel leaves; unsigned; estimated total diamond weight: 5.00 carats; mounted in 18k gold; length: 2 7/8in.

The 1969 Tiffany & Company Blue Book featured a "Lily of the Valley" Brooch, designed by Donald Claflin. Designer Donald Claflin is most often recognized for his whimsical creations, often featuring fictitious characters typically defined by bold, colorful, unconventional gemstones and enamel; undoubtedly he had a sense of humor. As a skilled designer, Claflin also created landmark traditional jewelry, catering to the needs of Tiffany & Company's more conservative clients during his tenure there, from 1965 to 1977.

This "Lily of the Valley" brooch is the original prototype; it was produced in two styles: one set with enamel and diamonds, illustrated here, a naturalist version with diamond en tremblant flower heads, and another pave-set with diamonds which appeared in the 1969 Blue Book, both the same form and frame. Over the years, Tiffany & Company has featured both versions; in 1994 the enamel and diamond version of this brooch was advertised in the New York Times beckoning the beginning of spring. 

Master jeweler Andre Chervin, owner of Carvin French, and Claflin became close personal friends. Andre Chervin, a formally trained Parisian jeweler, immigrated to the United States in 1951. He was immediately recognized for his superior craftsmanship, using the finest quality materials, as well as for being an adroit enamellist. His work was so extraordinary that he was sought after and produced work for famous American jewelry houses such as Van Cleef & Arpels, Tiffany & Co., Cartier, Bulgari, Yard, and Verdura. 

Andre Chervin and Donald Claflin shared the same passion, interest and understanding of gems and jewelry. Ideas were discussed in the workshop and at the dining table. Sharing the same vernacular and vision made this working relationship ideal, unique and special. Jewels were produced seamlessly from concept to sketch to creation; all were fluid, luxurious, and finely executed – a rare collaborative example.

The inspiration for this brooch comes from the French custom of giving lily of the valleys on the first of May to celebrate spring. In 1941, May Day became an official French holiday. Gifting these delicate white fragrant bell-shaped flowers will porte-bonheur or bring good luck. The tradition of giving lily's of the valley is embraced throughout France and is seen as the return to happiness. As the flower of May, the lily of the valley also represents purity, humility and sweetness and is often incorporated in wedding and birth arrangements. This brooch represents and reflects a seldom seen simpatico that designer Donald Claflin and master jeweler Andre Chervin shared.
