18 Karat Tiffany & Co. Atlas Diamond Circle Roman Numeral Pendant White Gold

A timeless evocation of a New York icon, the modern Atlas Open pendant from Tiffany & Co. is inspired by the Atlas clock, which has long graced the facade of the celebrated luxury jewelry house’s New York City headquarters.

In 1853, sculptor Henry Frederick Metzler was commissioned to carve the nine-foot bronze-coated wood sculpture of Atlas, the Greek titan, holding a clock atop his shoulders. According to company lore, the phrase “a New York minute” originated when local residents began syncing their pocket watches to Tiffany’s public timepiece, one of the city’s first clocks and considered the most accurate in Manhattan. As the store moved uptown to Union Square and then to Fifth Avenue, so, too, did the Atlas clock, and it’s now as widely associated with the internationally renowned brand as the legendary “Tiffany blue” is.

In 1983, Tiffany design director emeritus John Loring (b. 1939) introduced the Atlas watch — and following its phenomenal success, the Atlas collection debuted in 1995. Incorporating the Roman numerals that adorn the Atlas clock, the new line, which also featured housewares alongside the Atlas Open pendant, rings and more, presented an entrée into the luxury brand by way of more casual, day-to-day designs in tune with fashion’s movement toward less formal styles. The collection’s addition of sterling-silver jewelry was entirely modern. Previously considered unworthy of high design, silver was rendered appealing through the work of marquee Tiffany designers such as Elsa Peretti and Paloma Picasso.

Tiffany & Co.’s Atlas Open pendant — now also available in different sizes and metals and featuring diamonds — references the famed sculpture’s graphic Roman numerals in bold cutouts along its curved rim. It is an example of the house’s continuity of good design.

Tiffany & Co. is one of the most prominent purveyors of luxury goods in the United States, and has long been an important arbiter of style in the design of diamond engagement rings. A young Franklin Delano Roosevelt proposed to his future wife, Eleanor, with a Tiffany ring in 1904. Vanderbilts, Whitneys, Astors and members of the Russian imperial family all wore Tiffany & Co. jewelry. And Jacqueline Kennedy Onassis preferred Tiffany china for state dinners at the White House.

Although synonymous with luxury today, the firm started out rather modestly. Charles Lewis Tiffany and John B. Young founded it in Connecticut as a “stationery and fancy goods emporium” in 1837, at a time when European imports still dominated the nascent American luxury market. In 1853, Charles Tiffany — who in 1845 had launched the company’s famed catalog, the Blue Book, and with it, the firm’s signature robin’s-egg blue, which he chose for the cover — shifted the focus to fine jewelry.

In 1868, Tiffany & Co. gained international recognition when it became the first U.S. firm to win an award for excellence in silverware at the Exposition Universelle in Paris. From then on, it belonged to the pantheon of American luxury brands.

At the start of the Gilded Age, in 1870, Tiffany & Co. opened its flagship store, described as a "palace of jewels" by the New York Times, at 15 Union Square West in Manhattan. Throughout this period, its designs for silver tableware, ceremonial silver, flatware and jewelry were highly sought-after indicators of status and taste. They also won the firm numerous accolades, including the grand prize for silverware at the Paris Exposition of 1878. Among the firm’s glittering creations from this time are masterworks of Art Nouveau jewelry, such as this delicate aquamarine necklace and this lavish plique-à-jour peridot and gold necklace, both circa 1900.

When Charles Lewis Tiffany died, in 1902, his son Louis Comfort Tiffany became the firm’s design director. Under his leadership, the Tiffany silver studio was a de facto design school for apprentice silversmiths, who worked alongside head artisan Edward C. Moore. The firm produced distinctive objects inspired by Japanese art and design, North American plants and flowers, and Native American patterns and crafts, adding aesthetic diversity to Tiffany & Co.’s distinguished repertoire.

Tiffany is also closely associated with diamonds, even lending its name to one particularly rare and exceptional yellow stone. The firm bought the Tiffany diamond in its raw state from the Kimberley mines of South Africa in 1878. Cut to create a 128.54-carat gem with an unprecedented 82 facets, it is one of the most spectacular examples of a yellow diamond in the world.

In a broader sense, Tiffany & Co. helped put diamonds on the map in 1886 by introducing the American marketplace to the solitaire diamond design, which is still among the most popular engagement-ring styles. The trademark Tiffany® Setting raises the stone above the band on six prongs, allowing its facets to catch the light. A lovely recent example is this circa-2000 platinum engagement ring. Displaying a different design and aesthetic (but equally chic) is this exquisite diamond and ruby ring from the 1930s.
