Natural Pyrite Cube-Shaped Crystals
Two top-grade pyrite crystals, carefully chosen for our collection.
Isometric or cubes are one of the simplest and most common crystal shapes found in minerals.
Some pyrite crystals can look as if they've been cut into that shape. However, it's purely the result of their internal atomic structure repeating in three dimensions.
The way atoms are arranged inside the crystal determines the external shape.
The distinctive grooves often present on pyrite crystals are called striations. Pyrite often grows by alternating between slightly different crystal faces, and this alternating growth produces these parallel lines.
Changes in temperature, pressure, or chemical composition are believed to alter the rate and direction of crystal growth.
These pyrite crystals exhibit a metallic lustre and reflect beautifully. They're unique pieces that would make a great addition to any rock and mineral collection.
The crystal on the right has some white calcite filling the gaps between the crystals.
The crystal on the left in our photos is number 1 in our dropdown menu.
