Aquamarine is not a rock, it is a mineral.
The official name is beryl.
It forms in some pegmatites (late stage granites). So it has an igneous origin.
Since is resistant to erosion, you can also found them in some sedimentary rocks. But they are derived originally from an igneous process.

Aquamarine is related to the emerald, both belonging to the beryl family and is of igneous origin. The colour of aquamarine, however, is usually more even than that of the emerald. Much more often than its famous green cousin, aquamarine is almost entirely free of inclusions. Aquamarine has good hardness (7.5 to 8 on the Mohs scale) and a wonderful shine. That hardness makes it very tough and protects it to a large extent from scratches. Iron is the substance which gives aquamarine its colour, a colour which ranges from an almost indiscernible pale blue to a strong sea-blue. The more intense the colour of an aquamarine, the more value is put on it.
