Ferruginous quartz cluster Hydroxyapophyllite Native to Europe

Native to Europe

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

Typical stalactitic chalcedony is like a small cave lined with stalactites

and some pieces have hollow cores

The pseudo-hexagonal crystals grow similar to the arms of its namesake snowflake

Ferruginous quartz cluster Hydroxyapophyllite Native to EuropeLocale: Morocco Approx dimensions: 4. 5 x 3 x 3", longest crystal 5. 5 cm Approx weight: 627g 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.
