Specimen # 200470
Mineral: Hematite
Location: Graves Mountain, Lincoln Co., Georgia, USA
Size: 6.5 x 5.3 x 5.0 cm


This is a great specimen of iridescent hematite/goethite – under magnification, one can see that it has a stalagmitic-type habit. The iridescence is caused by thin layers of hematite, acting as a diffraction film, and has wonderful colour. This material is sometimes known by an old name, “turgite”, which was originally thought a separate mineral, and is now still colloquially used to describe iridescent hematite or goethite, sometimes seen on labels as a “variety” of such mineral.  In excellent condition and stands perfectly for display as photographed. From the Pete Richards collection, he collected this piece on March 28-29, 1987.
