No, sapphires are typically blue in color. Red sapphires are actually a specific type of corundum called rubies. Rubies are red due to the presence of trace elements like chromium in their crystal structure.
Pearls are not crystalline and don't have a crystal shape.
Sapphires are formed when heat and pressure are applied to the mineral corundum. A sapphire can be any color but red. Impurities introduced in to the corundum during crystal formation dictate the final gemstone color.
Agate, being a cryptocrystalline (microscopic crystal structure) form of quartz, does not have a crystal shape.
minerals get its crystal shape by the heating and pressure from rock
Sapphires are blue because of the presence of trace elements, mainly iron and titanium, in their crystal structure. These elements absorb certain wavelengths of light, causing the sapphire to appear blue to the human eye.

Crystal Symmetry is the ability of a crystal to shape by nature and has a symmetrical shape. It's also referred about the occupation of diamond cutters.

The shape of an ionic crystal depends on the arrangement of the ions in the crystal lattice, which is determined by the sizes and charges of the ions involved. The coordination number and geometry of the ions also influence the overall shape of the crystal.
