Mineral key

Your specimen may be a mineral. Minerals make up rocks and are sometimes found as pure, separate crystals. These crystals have distinctive properties that can help us to identify them: colour, crystal form (the shape of the crystal), hardness, lustre and streak (the colour the mineral leaves when rubbed on an unglazed piece of pottery).
The key below will help you to identify four different minerals. Minerals can be quite tricky to identify, so if you need more help why not consult the staff at your local museum or
click here to search the Virtual Store.

What colour is your mineral?
