"Aquamarine refers to beryl that is pale blue, light blue-green, or even light green. It is usually clear, but iron content gives it its blue/green color.

Aquamarine gemstones that are milky or included are much less expensive. When faceted, aquamarines are usually eye-clean, but stones with eye-visible inclusions are fashioned into cabochons, beads, or carvings. With a hardness of 7.5 – 8 on the Mohs scale, aquamarine is tough and durable—a good choice for jewelry worn every day.
The majority of aquamarine is mined in Brazil where the largest crystal ever found weighed in at a whopping 242 lbs. In the United States, aquamarine can be found in North Carolina and also in Colorado, where it is the state gem.
