The Legacy of Garnet in Jewelry Design

Vintage and antique garnet jewelry has been around for a long time.

Garnets have been used for adornment going all the way back to the Bronze Age. While we will never know if garnets can be used to prevent plagues or heal warriors, as has been suggested, we do know that both the Egyptians and the Romans felt that it was a worthy stone to set in gold for their nobility. In more “recent” times, garnets were ubiquitous in Victorian jewelry. The “G” in REGARD rings, the equivalent of the modern-day engagement ring, implied garnet.

Garnets were also highly valued in the region of Bohemia. The Smithsonian Museum of Natural History has in its collection an antique hairpin with Bohemian pyrope garnets from the Czech Republic. Bohemian pyrope got its name from Bohuslav Balbín, sometimes referred to as the “Czech Pliny,” in 1679. Abundant in the region, it was used often in jewelry during this time. In fact, it became so popular that in 1762, Empress Marie Terezie forbade its export. Stonecutting workshops opened in several regions across Bohemia, and pyrope became the country’s mineralogical symbol. While there was never a decline in its popularity, it was only in the mid-20th century that garnets enjoyed a revival.

Garnets can come in many shapes and sizes — one of the largest ever discovered is a 68.82-carat Tsavorite garnet. This stone is also in the collection of the Smithsonian Museum of Natural History.

According to the Gemological Institute of America, Brazil’s mines are rich in garnets, including spessartine, which can also be found in the Myanmar area, recognized for a specific shade of reddish-orange. While red garnets are the most popular, garnets actually come in a medley of colors.

Finding the Right Loose Gemstones for You

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.
