Aquamarine is a pale-blue to light-green variety of the beryl family,[2] with its name relating to water and sea.[3] The color of aquamarine can be changed by heat, with a goal to enhance its physical appearance (though this practice is frowned upon by collectors and jewelers).[4] It is the birth stone of March.[5]

Aquamarine is a fairly common gemstone,[6] rendering it more accessible for purchase, compared to other gems in the beryl family.[7] Overall, its value is determined by weight, color,[5] cut, and clarity.[8]

It is transparent to translucent and possesses a hexagonal crystal system.[9] Aquamarine mainly forms in granite pegmatites and hydrothermal veins,[10] and it is a very lengthy process that can take millions of years to form.[9]

Aquamarine occurs in many countries over the world, and is most commonly used for jewlery, decoration and its properties.[11]

Aquamarine is mainly extracted through open-pit mining, however underground mining is also a possibility to access aquamarine reserves.[12]

Aquamarine is a durable gemstone, but it highly recommended to conserve it on its own to prevent damage/scratches.[9]

Famous aqumarines include the Dom Pedro, the Roosevelt Aquamarine, the Hirsch Aquamarine, Queen Elizabeth's Tiara, Meghan Markle's ring, and the Schlumberger bow.[13]
