Beryl (Var: Emerald)
Itabira, Iron Quadrangle, Minas Gerais, Southeast Region, Brazil

Not from Columbia, but from BRAZIL - a cluster of maybe a DOZEN tightly intergrown crystals of bright green emerald! They are completely joined at one end, so you could probably call this a compound crystal. The crystals are not gemmy enough to cut, but they definitely qualify as "translucent to transparent" rather than opaque or just "translucent." And, they have the best bright emerald green color.
