Network solids, or network atomic solids, are large crystals with covalent bonds holding the atoms together. Gemstones including diamonds and rubies are network solids. Crystalline solids have a constituent arranged in ordered patterns and include amethyst quartz.
A solid that consists of densely packed atoms but lacks a crystalline structure is called an amorphous solid. A solid that is composed of microscopic crystals is said to be aphanitic.
Crystals
In the solid state ionic crystals are not dissociated in ions.
Solid crystals have a fixed, ordered arrangement of molecules or atoms, while liquid crystals have a partially ordered structure that can flow like a liquid but still exhibit some properties of a solid. Solid crystals have a defined melting point where they transition to a liquid state, while liquid crystals have a range of temperatures over which they exhibit liquid-like and solid-like properties.

A mineral is a solid material made up of crystals. Crystals are solid materials with a repeating, symmetric arrangement of atoms or molecules. When minerals form, their atoms or molecules arrange themselves into a crystal lattice structure.
Copper sulfate in the solid form are crystals
Snow consists of tiny ice crystals.
Clouds are not solid; they are made up of water droplets and ice crystals.
Phosphorus can, in fact, exist as covalent crystals in the solid state. Phosphorus usually exists in the solid state as non-covalent crystals. Under intense pressure, however, the bonds can become covalent.
They are in the solid state.
Salt (NaCl) is an inorganic compound that is found in nature as solid crystals.
