Quartz, Hedenbergite, Goethite
Cabinet, 11.0 x 9.1 x 4.2 cm
San Antonio Mine (San Antonio el Grande Mine), East Camp, Santa Eulalia District, Mun. de Aquiles Serdan, Chihuahua, Mexico
This plate of glassy, flashy quartz from the Glover collection is distinctive due to the rich inclusions of hedenbergite and goethite, which give the crystals a rich mossy color. Fine quartz specimens are unusual from the San Antonio Mine, and actually, except for the amethyst variety, are not all that common from Mexico in general.
