Origins and Formation
Aquamarine is a variety of the mineral beryl, which also includes emerald and morganite. Its name is derived from the Latin words "aqua" (water) and "marina" (sea), reflecting its sea-like coloration. Aquamarines form in granite pegmatites through a process involving high temperatures and pressures, which allows beryllium, aluminum, and other elements to crystallize.
Geological Formation
- Granite Pegmatites: Aquamarines typically form in granite pegmatites, where the right combination of elements and conditions allows for the growth of large, clear crystals.
