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.
