ROCK TRIVIA: AQUAMARINE ( March Birthstone )
Aquamarine is in the Beryl family of stones with the Emerald ( green) and Morganite (pink). beryl. Aquamarine’s color range is from blue to green-blue. The gem’s most valuable color is a dark blue to slightly greenish blue with good intensity. In general, the purer and more intense the blue color, the more valuable the stone. Most aquamarine is a light greenish blue. Aquamarine is pleochroic, which means it shows different colors in different crystal directions—in the case of aquamarine, one is almost colorless and so the the blue is always the cutting orientation.
good quality Aquamarine remains expensive. Brazil is a major producer of Aquamarine, with a deep blue found from Medina in Minas Gerais. Pakistan produces top quality Aquamarine, and some of the crystals can be huge gem quality giants.
Beautiful Aquamarine has been coming out of China Nepal and Russia. Burma (Myanmar) is also an important producer, as are Nigeria, Madagascar and a small, beautiful find in Namibia. U.S. localities that produce gemmy Aquamarine crystals are Colorado; Idaho and California.
