The Legacy of Sapphire in Jewelry Design

On 1stDibs, shop the bright blue gems that star in sapphire rings, sapphire necklaces and other vintage and antique sapphire jewelry

Sapphires — the stone of choice for Napoleon, Princess Diana and Elizabeth Taylor — have been a favorite of aristocrats and the well-to-do since the time of the Ancient Greeks.

Picture a sapphire. If the stone you conjure is a deep cornflower blue, you’re seeing only part of the picture. Although blue Kashmirs are considered the most valuable, sapphires come in every color except red. No matter the hue, this very special gem is rich in history and beloved by royals (FYI, Princess Diana and Kate Middleton share an 11-carat sapphire engagement ring), so September babies are in very noble company.

America’s version of royalty — old money and celebrities — have also shown a predilection for the blue stones. In 1940, John D. Rockefeller Jr. had Cartier mount a 62-carat sapphire he had bought from an Indian maharajah in a brooch for his first wife, Abby Aldrich Rockefeller; in 2001, the piece sold for a then-record of $3,031,000 at Christie’s New York.

The grand dame of jewelry, Elizabeth Taylor had a passion for the gems that her lovers were happy to indulge. Second husband Michael Wilding gave her an engagement ring set with a cabochon sapphire, while Richard Burton famously presented her with a BVLGARI sautoir set with diamonds and sapphires, including at its center a cabochon Burmese weighing 52.72 carats. One of the star lots in the sale of Taylor’s jewels at the Christie’s New York in 2011, it sold for $5,906,500.

You don’t have to have blue blood or a bulging bank account, however, to get an eyeful of this much-coveted gem. A number of outstanding examples reside in public collections.

The Smithsonian Museum of Natural History owns the 423-carat Logan sapphire, a gift from the Guggenheim family, and the Hall sapphire and diamond necklace, designed by Harry Winston and featuring 36 fine, well-matched cushion-cut Sri Lankan sapphires weighing a combined 195 carats. Also in the collection is the Bismarck sapphire necklace, designed by Cartier and sporting a central sapphire weighing 98.6 carats, which Mona Von Bismarck donated to the museum.

Sapphires are composed of corundum. Their color derives from trace elements, such as iron, titanium, chromium, copper or magnesium. When the trace element produces a ruby hue, the stone is called, what else, a ruby. (which is, as mentioned above, why sapphires cannot be red by definition).

The allure of large gemstones endures throughout the periods characterized as vintage, and sapphire features frequently in vintage engagement rings. (On 1stDibs, a range of buying guides can be found for those in the market for antique engagement ringsvintage engagement rings or Art Deco engagement rings.)

Questions About Calibre Cut Sapphire
  • 1stDibs ExpertApril 5, 2022
    A calibre cut is a specific type of cut gemstone used in jewelry. Normally, the term describes jewelry that features multiple small faceted gemstones in square, oval or rectangle shapes arranged closely together to form outlines or accent lines. Find a selection of calibre cut gemstone jewelry on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    Not to be confused with an emerald gemstone, an emerald-cut sapphire is a sapphire cut into a rectangular shape. An emerald-cut adds the illusion of flashing lights across the stone with its unique shape and step-cut along the edges. Browse a wide selection of sapphire jewelry in a variety of cuts on 1stDibs.
  • 1stDibs ExpertOctober 12, 2021
    The best cuts for a blue sapphire are said to be oval, round, and cushion. The look of an oval-cut sapphire is similar to that of a round sapphire. The slightly extended shape, on the other hand, can make it appear larger than a similar-weight stone. A round cut is one of the most traditional shapes, and it helps a gem dazzle to its full potential. The presence of about 58 facets results in a large amount of light being reflected. Cushion cut, sometimes known as the 'pillow-cut,' has been popular for generations due to its cushion-like appearance. The gemstone has a rectangular form with soft, slightly rounded corners in this cut. Typically, the crown has 58 to 64 big facets. These cuts were popular in numerous forms of jewelry, including rings, pendants, and earrings. Find a wide variety of blue sapphire jewelry on 1stDibs.
