The Basics: What is an Aquamarine?
Aquamarines, named after the Latin words for “water” (aqua) and “sea” (marine), are a variety of the mineral beryl. Their captivating blue to blue-green hues are reminiscent of the ocean, evoking images of serene sea waters and sunny beach days. The gemstone gets its colour from traces of iron within the beryl crystal structure.
A Rich History: Legends and Lore
Aquamarines have a storied past steeped in legend and lore. Ancient mariners believed that these gems were the treasure of mermaids and carried them as talismans to ensure safe passage across stormy seas. Romans and Greeks thought aquamarines could calm the waves and were a symbol of eternal youth and happiness.
In the Middle Ages, aquamarines were believed to possess healing powers, particularly for ailments related to the eyes, liver, and throat. They were also thought to bring clarity of mind and protect against poisoning.
Characteristics and Grading
When evaluating aquamarines, gemologists consider several factors, including colour, clarity, cut, and carat weight.
Colour: The most valuable aquamarines are a deep, vibrant blue with minimal green undertones. However, colour preference can be subjective, and many people appreciate the subtle greenish-blue hues.
Clarity: High-quality aquamarines are typically eye-clean, meaning they have no visible inclusions to the naked eye. Inclusions can impact the gem’s overall beauty and value.
Cut: A well-cut aquamarine will enhance its colour and brilliance. Popular cuts include emerald, oval, and cushion shapes.
Carat Weight: Aquamarines come in a wide range of sizes, from small stones suitable for earrings to large, statement pieces for rings and pendants.
Famous Aquamarines
Some aquamarines have achieved fame for their size, beauty, or historical significance. One of the most renowned aquamarines is the “Dom Pedro,” the largest cut aquamarine in the world, weighing an astounding 10,363 carats. This gem is a masterfully cut obelisk and is displayed at the Smithsonian Institution in Washington, D.C.
Care and Maintenance
Aquamarines are relatively durable gemstones, ranking 7.5 to 8 on the Mohs scale of hardness. However, they still require proper care to maintain their brilliance. To clean an aquamarine, simply use warm, soapy water and a soft brush. Avoid harsh chemicals and ultrasonic cleaners, as they can damage the gem.
