RM2804   Quartz with Halloysite inclusions, "mango quartz"

Cabiche mine, Cabiche, Quípama, Boyacá, Colombia

Quartz specimens from this Colombian mine, located in the Boyacá emerald mining area, have been well known since the end of the last century. By 2017, new galleries were opened those located different geodes. These crystals, called "mango quartz" or "crown quartz" were found in them, with inclusions that, after being recently analyzed, were determined as halloysite. The inclusions show filamentous structures and the tips of the crystals turn to orange tones. On our website we have already sold some samples with these inclusions on sale, without the orange coloration. Really aesthetic and on a matrix with goethitized dolomite-siderite.


Size: 8.2 x 7.7 x 4.5 cm.
Main crystal: 5.5 cm.
Found in 2018.
