Known as red or ferruginous (iron-bearing) quartz, this unusual variety of quartz gets its color from iron oxides, typically hematite. The quartz in this specimen initially grew colorless; broken crystals along the edge reveal the quartz crystals have a clear core bordered by a thin top layer of brick-red quartz. A change occurred during the growth process that introduced fine iron oxide inclusions that give the top layer deep color and a fairly matte luster.

Ferruginous quartz is typically fairly opaque due to the density of iron oxide inclusions, but some of the larger crystals on this specimen have decent translucency with backlighting. An amorphous grainy overgrowth coats one side of the specimen, and has a slight glitter like sand.

This large cluster sits well at an angle as a display piece with several large points splaying up and out of one end.

** Significant crack along the edge detailed in image 8 and will be marked on the specimen; the piece would not lose any key features without it, but use caution placing pressure on that section as it is liable to pop off!
