Oval Blue Natural Sapphire For Sale on 1stDibs

On 1stDibs, you can find the most appropriate oval blue natural sapphire for your needs in our varied inventory. Each design created in this style — which was crafted with great care and often made from Gold, 18k Gold and White Gold — can elevate any look. In our selection of items, you can find a vintage example as well as a contemporary version. Finding the perfect oval blue natural sapphire may mean sifting through those created during different time periods — you can find an early version that dates to the 19th Century and a newer variation that were made as recently as the 21st Century. Creating an oval blue natural sapphire has been a part of the legacy of many jewelers, but those produced by House of R&D, D and A Style and Fine Jewels UK are consistently popular. An oval cut version of this piece has appeal, but there are also round cut and mixed cut versions for sale. When shopping for an oval blue natural sapphire, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a Oval Blue Natural Sapphire?

Prices for an oval blue natural sapphire can differ depending upon size, time period and other attributes — at 1stDibs, these accessories begin at $123 and can go as high as $297,000, while this accessory, on average, fetches $5,599.

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 rings, vintage engagement rings or Art Deco engagement rings.)  

Find an exquisite collection of vintage and antique sapphire jewelry on 1stDibs.
