Tiger Iron

Tiger Iron consistes of narrow alternating and undulating bands or layers of golden Tiger Eye, silver/black metallic Hematite and red, brown or black Jaspilite.

Tiger Iron forms by Hematite, quite a common form of iron oxide, growing with Jasper and the oxidation of iron colouring the Jasper red. This causes the presence of banded Hematite and Red Jasper. However, what seperates Tiger Iron is the rare presence of Tiger Eye in these banded iron formations. Tiger eye forms when strands of Rocidolite imbed in and oxidize with similar bands of quartz- leading to a gold to yellow brown banded crystal- however in order for Rocidolite to reach this age of formation, it had to be leached down by rain through sedamentary minerals to be silicified with the Hematite and Jasper.

During its formation, much of the deposit was subject to incredible heat and pressure which has resulted in the bands of the rock being folded.

The hardness of the stone varies in accordance to different parts of the stone- Tiger's Eye is 5.5 - 6 Moh's; Hematite is 5 - 6.5 Moh's; and Jasper is 6.5 - 7 Moh's.
