A relative hardness value of 6.5 means that the mineral could scratch orthoclase (feldspar) but not quartz.

These include turquoise and moldavite. “Everyone has a different response energetically to specific crystals, so if you share your bed with another, it’s best to explore their receptivity before adding to the bedroom,“ says Winquist.

These 32 possible combinations result in the 32 crystal classes. These are often also referred to as the 32 point groups.

There are six basic crystal systems.

• Isometric system.
• Tetragonal system.
• Hexagonal system.
• Orthorhombic system.
• Monoclinic system.
• Triclinic system.

Crystallography is the study of atomic and molecular structure. Crystallography began with the study of crystals, like quartz. Today, crystallographers study the atomic architecture of any material that can form an orderly solid – from diamonds to viruses.
