The article discusses a signature specimen of Elbaite, also known as "gem tourmaline," from the Cruzeiro Pegmatite in Minas Gerais, Brazil. Elbaite is highly valued for its range of colors, crystal size, and aesthetic appeal. The specimen, known as the "Jolly Green Giant," is a large crystal surrounded by smaller crystals on a quartz base. It is a deep green color with color zoning and is embedded in translucent quartz.
