Amethyst, Citrine
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.

Are you shopping for diamonds and other loose gemstones to create your own custom jewelry?
Why might you purchase a diamond or gemstone “loose” — that is, on its own, not mounted in a piece of jewelry? Perhaps you’re a connoisseur looking to acquire a unique investment. The scarcity of high-quality colored diamonds, for instance, especially pink diamonds, means that their value increases over time; the same is true of rare Kashmir sapphires and Burmese rubies. Far rarer than diamonds, Paraiba tourmaline, discovered only in the 1980s, is treasured as much for its extraordinary color as its scarcity, both of which contribute to its high value.
A more common scenario would be that you’re hoping to create a very special piece of custom jewelry, such as an engagement ring or a milestone-birthday present, and want to personally select the most beautiful, unusual, or ultra-rare stone you can find and afford. Doing so adds to the romance and substance of the gift and can be a part of the story told as the jewel is passed from generation to generation.
If this sounds like you, read on for tips on becoming one of the world’s savviest gem hunters.
Educate yourself: When buying any piece of gem-set fine jewelry, you should familiarize yourself with the factors that determine a stone’s price. This will enable you to streamline your search for the perfect gem and have intelligent, productive conversations with sellers.
There is a wealth of information online, such as our diamond-buying guide and this overview of colored gemstones for engagement rings. The buying guides of the Gemological Institute of America (GIA), searchable by stone type, are also a widely trusted source for consumers venturing into the world of diamonds and gems for the first time.
Vet your vendor: If you peruse 1stDibs with any regularity, you know there is no shortage of vendors who deal in top-quality loose gemstones. (Read about our vetted sellers.) Finding a trustworthy, established dealer may be as easy as getting a recommendation from friends or family. And, although it may sound obvious, it pays to Google your candidates — and consult customer reviews — before making contact.
Harakh Mehta, designer and founder of the Mumbai, India–based fine-jewelry brand Harakh, has an innate understanding of proper client relations, especially when the customer is in unfamiliar territory. “Start chatting with the dealer, get to know them better," he says. "It’s very important to establish a comfort level. We never push a sale, as we want it to be a carefully considered purchase. So, if the client is not in a rush, we do it over a few virtual meetings or phone calls.”
Request documentation: The best dealers go to great lengths to furnish clients with documents verifying the quality rating, natural origin and provenance of a stone — showing, for example, that loose emerald hails from the famous Muzo mine in Colombia — and disclosing any treatments applied to enhance its appearance. (And who doesn't love emerald jewelry? The most valuable emeralds are the ones that have a deep bluish-green to true green color and no visible inclusions.)
If no grading report is available for a stone you are interested in, the dealer should be able to provide an authenticity document, such as an appraisal or info sheet, that has been signed by an in-house gemologist or professional appraiser. Google those names, too, for extra peace of mind.
Ask for videos and visuals: When transacting with a gem dealer online, you should always request real-time videos and photographs, since professional photos of a stone, usually on a white background, have likely been retouched for optimal presentation.
