The Legacy of Aquamarine in Jewelry Design

Perhaps the one gemstone that best embodies the glimmering blue of the ocean is aquamarine, not just in name but also in color. Aqua marina (Latin for water and sea), March’s birthstone, is often crystal clear and blue. Often affordable in price, vintage and antique aquamarine jewelry belongs in everyone’s jewelry box.

Aquamarine is a precious gemstone from the mineral beryl family. Its cousin is the emerald. Like other beryl varieties, aquamarines are rated 7.5 to 8 on the Mohs Hardness Scale. This means that they are soft enough for jewelers to cut to their client’s specs but also durable enough for daily wear.

On land or sea, aquamarines feature prominently in many folk tales, including one about mermaids gifting aquamarine to sailors to protect them during sea voyages. Worn around sailors’ necks as an amulet, it kept them from getting seasick and, most importantly, from shipwrecks. Considered a symbol of courage by some, aquamarine amulets were also favored by Egyptian and Hebrew warriors during battle.

Aquamarine has also made appearances on some of the grandest of great dames. The Brazilian government gifted Eleanor Roosevelt with a 1,847-carat aquamarine in 1935 and Queen Elizabeth II received a sizable aquamarine upon her 1953 coronation; this stone is now the focal point of her aquamarine tiara. And renowned Tiffany Co. designer Jean Schlumberger made a diamond Bow setting for a 148.5-carat aquamarine, which was originally exhibited at the 1893 World’s Columbian Exhibition, now in the collection of the Field Museum of Natural History in Chicago.

On 1stDibs, find a range of vintage and antique aquamarine jewelry that includes unique aquamarine rings, necklaces and other accessories.

Finding the Right Drop-necklaces for You

Also called Y necklaces as they are designed to hang a certain way, vintage drop necklaces are striking and adaptable. They can enhance everything from a casual sweater-and-jeans combo to an elegant heels-and-evening-dress pairing.

Adornment is an ancient human practice, with archeologists identifying early jewelry made from bones, claws and shells. As technology has advanced, so too have jewelry designs and the design of necklaces, from the simple to the intricate.

Drop necklaces come from lariat-style necklaces, which are chain necklaces that end in a tassel or pendant. A drop necklace’s design, meanwhile, is long with open ends, and it usually does not have a clasp. It consists of a single chain that wraps around the neck and a centerpiece — sometimes featuring a diamond or pearls — that hangs down to the middle of the chest. Drop necklaces frequently come in lengths from 16 to 20 inches, with the vertical lines making them appear longer than other necklaces of the same length.

Drop necklaces are extremely versatile, able to be worn knotted, draped or looped. They can be chunky statement pieces or thin, minimal designs. The range of drop necklaces that can be found on 1stDibs can accentuate the plunging necklines of modern looks or add flair to a basic ensemble.
