Marambaia
Aquamarine- and topaz-bearing pegmatites 70 km N of Teófilo Otoni.
"Aquamarines too have capitalized in recent years on the quality of Brazilian specimens. An early find, in 1910, weighed in at more than a hundred kilogrammes, a phenomenal weight. The colossal Marambaya [sic] aquamarine crystal, as it is known, would today be worth over US$ 25 million. At the time it was of little more than curiosity value." [Sauer, 1982, p. 13].
"In 1910 a single aquamarine crystal, which produced a staggering 550,000 carats, was found in the Marambaia region in Minas Gerais state. This crystal, in terms of dimension alone, holds the world record in gem aquamarines. A second famous specimen, found in 1954, weighed 35 kilogrammes and is the most valuable to have been discovered in the world." [Sauer, 1982, p. 26.]
