On 1stDibs, you can find the most appropriate natural no heat sapphire for your needs in our varied inventory. Every item for sale was constructed with extraordinary care, often using Gold, Platinum and 18k Gold. In our selection of items, you can find a vintage example as well as a contemporary version. Making the right choice when shopping for a natural no heat sapphire may mean carefully reviewing examples of this item dating from different eras — you can find an early iteration of this piece from the 19th Century and a newer version made as recently as the 21st Century, both of which have proven very popular over the years. For this particular accessory, there are many different carat weights to choose from, but 1.5 Carat and 2 Carat versions are of considerable interest. A natural no heat sapphire from Dover Jewelry, Antinori Fine Jewels and Andreoli — each of whom created a beautiful version of this treasured accessory — is worth considering. See these pages for an oval cut iteration of this accessory, while there are also cushion cut cut and round cut cut versions available here, too. When shopping for a natural no heat sapphire, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a Natural No Heat Sapphire?

On average, a natural no heat sapphire at 1stDibs sells for $14,400, while they’re typically $1,200 on the low end and $650,000 for the highest priced versions of this item.

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 Natural No Heat Sapphire
  • 1stDibs ExpertApril 5, 2022
    A no-heat sapphire is a sapphire gemstone in its natural state. It differs from sapphires that undergo heat treatment to enhance their surface. Generally, no-heat sapphires are smoother, while heated sapphires are harder and more lustrous. Shop a range of sapphire gemstone jewelry on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    Yes, sapphires conduct heat. In fact, a real one won't melt until it reaches a temperature of 3,711 degrees F. As a result, one way that experts test sapphires to determine if they are real is to heat them to high temperatures. Find a collection of sapphire gemstone jewelry on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    Yes, Parti sapphires are indeed natural and cannot be manufactured in a lab. Three different colors can be seen in this stone, a mixture of blue, green and yellow. You can shop a collection of expertly vetted gems from some of the world’s top sellers on 1stDibs.
  • 1stDibs ExpertMarch 3, 2023
    One way to tell if a star sapphire is natural is to shine a flashlight on it while in total darkness. On a genuine star sapphire, the light that reflects off of the stone will be the same color as the stone. Glass and other materials used to create synthetic stones may show reflections in different colors. To be certain of the authenticity of a gemstone, take it to an experienced jeweler or appraiser for an evaluation. On 1stDibs, find a selection of star sapphire jewelry.
  • 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.
