Miniature hematite crystal from the N'Chwaning mine in the Northern Cape, South Africa.
This natural crystal has a highly reflective metallic lustre and comes in a mineral display box.
Hematite is an iron oxide mineral. It was first named by ancient Greek philosopher Theophrastus around 300 BC. He called it 'haimatitēs lithos' meaning 'blood-red stone'. This is likely to be because the streak is red.
