Large ferruginous quartz cluster Pyrite Approx size and weight 3/4–1

Approx size and weight 3/4–1 1/3 lb

all examples were translucent and not opaque

Very small crystals often dot the surface of the calcite

including some that looks almost like skeleton forms on the tip of the point

since this fluorite from this locale tends to have a cubic crystal habit

Large ferruginous quartz cluster Pyrite Approx size and weight 3/4–1Locale: Morocco Approx dimensions: 5. 5 x 4 x 2. 5", longest crystal 6 cm Approx weight: 772g 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
