Hardness of sphalerite
The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.Hardness Streak Cleavage Gravity Other Properties Chemical Composition Specific Mineral 1 - 5.5 Yellowish- None 3.5 - 4 Massive, coatings, botryoidal crusts, earthy Limonite brown masses.

Two minerals of note have differences in hardness depending on direction: Kyanite has a hardness of 5 parallel to the length of the crystal, and a hardness of 7 when scratched along a direction perpendicular to the length. Calcite has a hardness of 3 for all surfaces except the {0001} plane. On {0001} it has a hardness of 2. Pyrite is harder than sphalerite, with a Mohs hardness of 6 to 6.5 compared to sphalerite’s Mohs hardness of 3.5 to 4. Pyrite also has a higher specific gravity than sphalerite, meaning it is denser and heavier. Using pyrite and sphalerite interchangeably can lead to serious consequences in certain applications.
