Aquamarine is a mineral belonging to the beryl family, known for its blue-green hue reminiscent of marine waters. This mineral typically forms in granite pegmatites, where it crystallizes into well-defined hexagonal prisms. Its color, ranging from pale to deep blue, is primarily due to the presence of traces of iron. Aquamarine is a transparent to translucent mineral with a hardness of 7.5 to 8 on the Mohs scale, making it durable and scratch-resistant. It has a vitreous luster and excellent clarity, often free of inclusions visible to the naked eye. The most sought-after specimens are those with an intense blue color and exceptional clarity. In the field of mineralogy, aquamarine is studied for its crystallographic properties and chemical composition. Mineralogists are interested in its hexagonal crystal structure, which influences its optical and physical properties. Due to its beauty and durability, aquamarine is widely used in the jewelry industry, but it is also valued by mineral collectors.
