Fro example, Corundum (Sapphire and Ruby) was used to scratch Apatite. Corundum left a scratch on the surface of Apatite, and so this mineral should sit higher on the scale. The most important number on this scale of 7. Why? 7 is the hardness of Quartz, which is the hardest mineral that is commonly air born.

Apatite is the name for a group of phosphate minerals. This group includes hydroxyl-apatite, fluor-apatite (the most common variety) and chlor-apatite. Apatite is an abundant mineral, found in many types of rock. However most gem-quality mineral is extremely rare and it is associated with pegmatites.

Furthermore, the minerals from the group of apatite and polysomatic apatites are conchoidal and uneven fracture and the hardness on the Mohs scale is 5. How to conduct a hardness test on an unknown rock or mineral using Mohs into that relative hardness range are calcite (H=3), fluorite (H=4) and apatite (H=5 ). Apatite is a mineral of medium hardness and is used to represent 5 on the Mohs scale.

Apatite has a relatively consistent hardness and serves as the index mineral for a hardness of five in the Mohs Hardness Scale. Specimens with excellent clarity

Apatite is the name of a group of phosphate minerals that have a familiar chemical composition and share the same physical properties. They are a significant component of phosphorite and used to make chemicals, acids, and fertilizers. Apatite has a consistent hardness and serves as the index mineral for a hardness of 5 in the Mohs Hardness Scale. 2012-05-15 2021-03-23 Blue Apatite Meanings, Zodiacs, Planets, Elements, Colors, Chakras, and more.

The graph shows the great difference between the Vickers hardness of corundum and diamond - which are only one unit apart on the Mohs hardness scale. Apatite occurs as hexagonal crystals in igneous, metamorphic, and sedimentary rocks, and is used as a source of phosphate for making fertilizers.
