JordanCrystal shape is determined by the internal arrangement of atoms within the crystal lattice, as well as external factors such as temperature, pressure, and solution composition during crystal formation. Differences in growth rate along different crystallographic axes can also influence the final shape of a crystal.

What do crystal shapes have to do with minerals?
Crystal shapes are determined by the internal arrangement of atoms within a mineral. The specific atomic structure of a mineral dictates how it will grow as a crystal. Different minerals have characteristic crystal shapes that can be used to identify them.
What are crystal form and cleavage?
Crystal form refers to the natural geometric shape of a mineral crystal, which is determined by its atomic structure. Cleavage is the tendency of a mineral to break along distinct planes of weakness due to its internal atomic arrangement. Cleavage can be described in terms of the number of planes, angles between them, and the quality of the cleavage surface.
Does a calcite crystal look like diamond to the naked eye?
A calcite crystal comes in a variety of sizes and shapes. There are some that do look like a diamond to the naked idea but you can tell that they are different if you look closely.
How many crystal shapes are there?
Mineral crystals are generally categorized into six different classes, depending on the number, length, and angular relationships between their axes. Their shapes or habits, however, are enormously varied. See the link below.
Is the crystals in each mineral are the same shape true or false?
Most minerals have one crystal shape each, but that shape may be different for a different mineral. However there are a few substances which form different shapes of crystal under different conditions. This is called polymorphism, or allotropy if the substance is an element. For instance carbon can form graphite or diamond.
