Miniature hematite crystals from the N'Chwaning mine Northern Cape South Africa. Striations can be seen on some of the faces which have a highly reflective metallic lustre. Some secondary minerals are also present but I can't say for certain what they are. I have put out enquiries and will update this listing when I receive more information.
This entire piece sparkles beautifully as it catches the light at certain angles.
Hematite which is an iron oxide was first named by Theophrastus (Ancient Greek philosopher and successor to Aristotle) around 300 BC. He named it 'haimatitēs lithos' meaning 'blood-red stone' which is believed to have come about because of its red streak. In mineralogy streak is a mineral in powdered form and is not always the same colour as the mineral.
The N'Chwaning mine is part of the Kalahari manganese field which sits amongst well preserved 2.2 billion year old sedimentary rocks in the Northern Cape of South Africa. This deposit has produced some of the world's finest examples of hematite.
This piece was carefully chosen during one of our many trips to South Africa.
