A crystals structure is defined by the particular repeating arrangement of atoms throughout the crystal. Colour This can result in single crystals or clusters of numerous crystals. When you look at a mineral you may recognise these familiar shapes. In the Triclinic crystal system all three axes are unequal lengths and none of the 3 axes intersect at 90°. Are its faces square, rectangular, or triangular? There are numerous crystal shapes, and when all of the variations are factored in, the number of crystal shapes is seemingly endless. Lustre Some minerals form a cubic, or a cube-shaped habit, such as halite, galena, and pyrite. The shape of the resulting crystaL-such as a cube (like salt) or a six-sided form (like a snowflake)-mirrors the internal arrangement of the atoms. perhaps the most beautiful crystals of all are gemstones.

Crystal shape As crystals grow, changes in temperature, pressure and chemical composition can directly affect the internal atomic pattern, thus changing the shape of the crystals, resulting in an almost endless variety of crystal patterns. The one exception is the Hexagonal crystal system which has 4 axes, 3 of equal length that intersect at 60° and a 4th longer axis that intersects the shorter 3 axes at 90°, which gives these crystals 6 sides. "So if the mineral grain stops growing at stage 3, its external shape is regular, and the grain is a crystal!! Habit is the general appearance a mineral tends to have – whether it is found as blocky crystals, long slender ones, or aggregates of some type, etc. Some crystals are so small they can be seen only with a magnifying glass, or sometimes, only with a microscope.
