Aquamarine is a variety of beryl. Colors are determined by impurities of iron. It is found in peg matite, a type of slow-forming igneous rock. Aquamarine forms in flat-top gem prisms that intergrow with muscovite plates and white feldspar. Aquamarine is a form of beryl, a hard (7.5-8 on the Moh's scale), clear mineral formed from beryllium, aluminum, silica, and oxygen. Its cousin is the more rare and expensive emerald. It can form in metamorphic rocks sometimes, but it's far more commonly associated with granite. As massive bodies of granitic magma slowly cool, aquamarine and other forms of beryl grow in vugs or pegmatite veins, nurtured by hot water saturated with metals and minerals.
