Amethyst Cabochon For Sale on 1stDibs

Surely you’ll find the exact amethyst cabochon you’re seeking on 1stDibs — we’ve got a vast assortment for sale. Every item for sale was constructed with extraordinary care, often using Gold, 18k Gold and Yellow Gold. Find an antique version now, or shop for 412 vintage or 367 modern creation for a more contemporary example of these cherished accessories. Making the right choice when shopping for a amethyst cabochon may mean carefully reviewing examples of this item dating from different eras — you can find an early iteration of this piece from the 18th 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 2 Carat and 2.5 Carat versions are of considerable interest. A amethyst cabochon from Polya Medvedeva Jewellery, Goshwara and Bulgari — each of whom created a beautiful version of this treasured accessory — is worth considering. A cabochon version of this piece has appeal, but there are also sugarloaf cabochon and oval cut versions for sale. When shopping for a amethyst cabochon, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a Amethyst Cabochon?

Prices for a amethyst cabochon can differ depending upon size, time period and other attributes — at 1stDibs, these accessories begin at $75 and can go as high as $159,670, while this accessory, on average, fetches $3,382.

The Legacy of Amethyst in Jewelry Design

There are few gemstones in the world that are both affordable and worthy of a duchess’s attention. But then not many stones are as beautiful as amethyst. Indeed, vintage and antique amethyst jewelry has innumerable fans, and February’s birthstone has many unique attributes. For the romantics, there are several tales in Greek mythology that tell the story of Bacchus and Amethyste, a maiden that he pursues yet is rescued by Diane by turning her into a white stone. Bacchus, mourning his love, pours a glass of wine over the sculpture, dyeing her purple.

Amethyst has adorned many royal jewels. One of the most enviable jewelry collections of all time belonged to Wallis Simpson, the Duchess of Windsor. In 1947, the Duke gifted her with a Cartier amethyst and turquoise bib necklace. This special order piece was made with twisted 18-carat and 20-carat gold, platinum, brilliant- and baguette-cut diamonds, one heart-shaped faceted amethyst, 27 emerald-cut amethysts, one oval faceted amethyst, and turquoise cabochons. The Duchess was not the only Royal with a penchant for the purple gemstone. The tiara now owned by Queen Silvia of Sweden is set with amethysts that once belonged to the French Empress Josephine. A stunning 56-carat cushion-cut, square-shaped amethyst set in an 18-karat yellow gold necklace designed by Tiffany Co. is now in the collection of the Smithsonian National Museum of Natural History.

The Smithsonian also has in its possession an even more rare example of fine amethyst: the 96-carat Morris Amethyst Brooch. The brooch features a deep, rich purple heart-shaped amethyst. The museum states that the piece was likely made during the Edwardian period (1901–15) “when platinum and diamonds were often used, and amethyst, a favorite stone of King Edward VII’s wife, Alexandra, was often included in jewelry of the era.”

Another amethyst necklace, with an even richer story, can be found in the Natural History Museum of London. Known as the Delhi Purple Sapphire (even though the stone is an amethyst), this stone was stolen from the Temple of Indra during the Indian Mutiny of 1857. Anyone in possession of this stone is bound to have terrible luck, including its owner Edward Heron-Allen, who gifted the gemstone to the museum thinking that this would save him but ended up transferring the bad luck to the museum curators overseeing the stone.

Find a wide range of vintage and antique amethyst necklaces, bracelets and other fine jewelry on 1stDibs.
