Collection of 10 Mohs Hardness Scale Minerals

Collection of Minerals from the Mohs Hardness Scale presented in a robust handcrafted natural wood box.

The Mohs scale is a list of ten Minerals ordered by their hardness, from lowest to highest. It is based on the principle that any substance can scratch other softer substances, without the opposite happening.

This collection contains 10 pieces in the classic 4x4 cm cardboard box format, including a natural diamond and a jeweler's loupe to observe each specimen in more detail. In addition, the labels are numbered in order of hardness and are colored so that you can easily learn to differentiate them.
The wooden box allows you to exchange the minerals and organize them as you like.

The Collection Includes 10 Representative Samples of the following Minerals:

• Talc – Hardness 1
• Plaster – Hardness 2
• Calcite – Hardness 3
• Fluorite – Hardness 4
• Apatite – Hardness 5
• Orthose – Hardness 6
• Quartz - Hardness 7
• Topaz – Hardness 8
• Corundum – Hardness 9
• Diamond – Hardness 10

The pieces you receive may differ slightly from the photo shown, as the minerals are natural and no pieces are identical. The size is approximate.

The minerals are glued with hot silicone. If desired, the silicone can be easily removed without damaging the piece with ethyl alcohol and thus separate them from the base where they are glued.
