Aquamarine’s Name
Aquamarine is the birthstone for March and the gem of the 19th wedding anniversary. The name is derived from two Latin words: aqua, meaning “water,” and marina, meaning “of the sea.” Can you picture a sunny and warm day on the Mediterranean Sea in August where the water is greenish blue?
Legend and Lore Due to its name, this gemstone is said to protect mariners against the harsh currents of the open sea. Wearing aquamarine was believed to increase intelligence, courage, happiness, wisdom, and youthfulness. Today’s aquamarine is considered a symbol of friendship, faithfulness, and courage. Knowing this, the gem is thought to reawaken the love of married couples and in folklore, to render soldiers untouchable and to bring victory to battles and legal disputes. For a more personal perspective, someone who wears aquamarine will receive help to deal with glandular disorders, fluid retention, and will help maintain the health of your eyes.
Origins You will find the largest deposit in Brazil, however lesser caches can be found in Pakistan, China, Myanmar, Russia, and Ukraine. More recently, Africa has established some mines in Mozambique, Kenya, Madagascar, Zambia, and Nigeria. Yet locally, a U.S. source is the Mount Antero area of Colorado and southern California.
Properties Aquamarine belongs to the Beryl family along with morganite and emerald. The light blue to greenish blue color is derived from iron. Its crystal structure is long pencil-like hexagonal formations in the host rock. Large pieces of rough can yield large gemstones and can come in faceted gemstones, cabochons, beads, and carvings. Rated 7.5-8 on the Moh’s hardness scale, it is just soft enough to not wear it every day in a ring or bracelet but could safely be worn as earrings, pendant, or brooch.
Selecting a Gemstone Aquamarine is available in large sizes and irregular shapes, making it a great go-to gemstone for custom order designs. According to the American Gem Trade Association (AGTA), “The darker and more saturated an aquamarine’s color is, the rarer and consequently the more valuable it is.” Compared to emerald, which is heavily included, aquamarine is much clearer, giving it a higher clarity grade. Large size, saturated light blue in color, and clean transparent clarity often command higher prices and thus are considered rarer in nature.
Enhancements Heat treatments are widely used to take material that is too green and make it the more acceptable light blue. This treatment is permanent and acceptable in the jewelry industry. However, if the saturated light blue color is found without heat treatment, it will command a higher value.
Famous Aquamarines As stated by GIA “In 1936 the government of Brazil gave First Lady Eleanor Roosevelt a dark blue rectangular step cut aquamarine that weighed 1,298 carats (ct). It was the larger of two stones faceted from a piece of aquamarine rough that itself weighed an impressive 2.9 pounds (1.3 kilograms). It is now housed at the Franklin D. Roosevelt Presidential Library and Museum in Hyde Park, New York. A celebrated attraction at the Smithsonian Institution is the 10,363 ct (about 4.6 pounds) Don Pedro Aquamarine – believed to be the largest faceted aquamarine in the world. The approximately 14 inch (36 centimeter) high obelisk was fashioned by acclaimed German lapidary Berndt Munsteiner using the fantasy cut technique (https://www.gia.edu/birthstones/march-birthstones#birthstone_1, found on March 2, 2021).”
How to Care for Your Aquamarine Use warm water, mild dish soap, and a toothbrush to scrub the gemstone and its mounting. Ultrasonic cleaning and steaming is acceptable as long as the gemstone doesn’t have any liquid filled fractures.
Designer Thoughts Because of aquamarine’s properties and crystal structure, designers enjoy working with the gemstone because it will yield a jewelry piece that is unique and wearable. Often gem cutters will facet an aquamarine in step cuts to show off the fine clarity and transparent nature of the gem. Many designers may choose to mount the gem in a yellow gold design to bring out a touch of green in the gemstone or in a white metal to highlight the desired light blue color.
