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.
Questions About Square Cut Aquamarine
- Why are emeralds cut in squares?1 Answer1stDibs ExpertApril 5, 2022Emeralds are frequently cut into squares due to their properties. Because they are brittle, the gemstones benefit from stronger rectangular and square shapes. Also, these cuts tend to hide the natural blemishes found in many emeralds. Shop a large selection of emerald gemstone jewelry on 1stDibs.
- 1stDibs ExpertApril 5, 2022No, a square emerald cut is not the same as an asscher cut. Although they have the same basic shape and are both step cuts that maximize clarity, the asscher cut shows off a sharper angle at the corners. Shop a wide variety of gemstone jewelry on 1stDibs.
- 1stDibs ExpertNovember 13, 2024What a square-cut diamond is called depends on how the jeweler arranged its facets. A princess-cut diamond has a square shape and a brilliant cut that maximizes its sparkle. Another square-shaped cut is the Asscher, which is stepped to show off a diamond's color and clarity. Find a large selection of diamond jewelry on 1stDibs.
