MULTI-COLOR AQUAMARINE BEADS, FACETED ROUNDELL SHAPE, 5-5.5MM

Aquamarine Beads, like emerald, heliodor, and morganite, is part of the beryl group.  Its name, which means “water of the sea” comes from the Latin words aqua (water) and mare (sea).  Most aquamarines are found in granite pegmatites, which form as liquid molten rocks that rise through fissures and cracks in the Earth’s crust.   The stone’s distinctive blue comes from traces of iron interacting with light.   Brazil is currently the prime source for aquamarines. Extraordinary crystals have been found there, including a 550,000-carat aquamarine crystal that was found in 1910.  Though, sky-blue and dark blue stones are now the most highly prized, in the 19^th century, sea-green stones were preferred. Most aquamarines today are heat-treated, which removes the green hues, resulting in a purer blue.
