The gem pegmatites of Minas Gerais are the world's foremost source of fine watermelon tourmaline, and São José da Safira among the most productive localities for large, well-formed specimens.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eA cabinet specimen presenting a vertical cluster of elongated prismatic tourmaline crystals displaying the characteristic concentric pink-and-green zoning that gives watermelon tourmaline its name, set on a matrix of smoky quartz.
