20 Carat Sapphire For Sale on 1stDibs

Surely you’ll find the exact 20 carat sapphire you’re seeking on 1stDibs — we’ve got a vast assortment for sale. Each design created in this style — which was crafted with great care and often made from Gold, 18k Gold and Platinum — can elevate any look. You can easily find a 1895 antique edition and 196 modern creations to choose from as well. If you’re looking for a 20 carat sapphire from a specific time period, our collection is diverse and broad-ranging, and you’ll find at least one that dates back to the 19th Century while another version may have been produced as recently as the 21st Century. For this particular accessory, there are many different carat weights to choose from, but .5 Carat and 1 Carat versions are of considerable interest. Creating a 20 carat sapphire has been a part of the legacy of many jewelers, but those produced by Luigi Ferrara, Tiffany & Co. and Cartier are consistently popular. See these pages for a round cut iteration of this accessory, while there are also oval cut cut and cushion cut cut versions available here, too. When shopping for a 20 carat sapphire, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a 20 Carat Sapphire?

Prices for a 20 carat sapphire can differ depending upon size, time period and other attributes — at 1stDibs, these accessories begin at $53 and can go as high as $6,500,000, while this accessory, on average, fetches $5,986.

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 20 Carat Sapphire
  • 1stDibs ExpertApril 5, 2022
    The highest carat sapphire to ever be discovered is the Blue Giant of the Orient, as of January 2022. It weighs 486.52 carats and originated from a mine in Ratnapura, Sri Lanka. On 1stDibs, shop a large selection of sapphire gemstone jewelry.
  • 1stDibs ExpertApril 5, 2022
    The term “20 carat gold” does not have a meaning. “Carat” is a unit of measurement used to describe the size of gemstones. “Karat” is the unit used to describe gold precious metal. Gold stamped as 20 karat or 20K is 83.3 percent pure gold and 16.7 percent metal alloy. You'll find a wide variety of gemstone jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    A standard size of a round sapphire is 6mm which is approximately one carat, making 7mm sapphires just slightly larger than a carat. Because sapphires are heavier than diamonds, a one carat sapphire is slightly smaller than a one carat diamond.
  • 1stDibs ExpertMay 5, 2023
    How much a 1-carat natural sapphire is worth depends on its color, cut and quality. Sapphires can range in value from $25 to thousands of dollars per carat. A certified appraiser or knowledgeable jewelry expert can examine a particular gemstone piece and give you an estimate of its value. On 1stDibs, find a collection of sapphire gemstone jewelry.
