Secondary Species: Beryl var. Aquamarine
Pocket: Angicos mine, Medina City, Minas Gerais, Brazil
Precious, mesmerizing, durable and timeless… these are a few words used to describe colored gemstones, a class of gemstones that includes various hard, colorful gem minerals such as tourmaline, topaz, and beryl. Large, transparent crystals of these gem minerals have always been coveted by collectors for both their aesthetic beauty and their high intrinsic value as gem materials.
Aquamarine, from the Latin word for seawater (in allusion to its vivid blue-green coloration), is a variety of the mineral beryl and occurs in high-quality crystals at many granite pegmatite deposits around the world. Few aquamarine localities, however, offer the incredible crystal size, perfection, and intensity of color that the Medina City pegmatite district in Brazil’s Minas Gerais Province does. Fine aquamarine crystals have been found here since the World War II era, with most ending up in aquamarine gemstones and jewelry around the world.
In May of 1997, a spectacular pocket of world-class aquamarine crystals was discovered at the Agnicos mine. Approximately forty aquamarine crystals were found, with four crystals (including this specimen) being world-class. The intense, saturated blue color, facet-quality interior, and spectacular, natural surface etching features make this one of the finest aquamarine crystals to be preserved intact from Brazil. Measuring nearly 30 cm tall and weighing over 1700 grams, this aquamarine crystal is absolutely mesmerizing to behold in person. This specimen was featured on the front cover of the Mineralogical Record magazine, Volume 4, 2002.
The 1997 Agnicos mine find is considered to be the most important aquamarine discovery in Brazil since 1967, nothing this significant has been found since that time in Brazil. This world-class gem crystal is worthy of serious consideration by an advanced collector or museum.
