Corundum is in the trigonal crystal system.
6 sided with a square figure
Corundum has a brittle fracture, which means it tends to break into sharp, irregular fragments. This is due to the strong atomic bonding within the crystal structure of corundum, which results in the propagation of cracks rather than plastic deformation.
Bauxite and corundum are both aluminum minerals. Bauxite is the primary ore of aluminum from which aluminum is extracted, while corundum is a naturally occurring crystal form of aluminum oxide known for its hardness and use in abrasives.
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.
Sapphire typically has a hexagonal crystal structure, with aluminum oxide (Al2O3) forming a dense, closely packed arrangement of oxygen and aluminum ions. This crystal structure contributes to sapphire's hardness and durability, making it a popular choice for jewelry and industrial applications.
Corundum ( (Al_2O_3) ) is hexagonal in crystal structure.

The scientific name for a ruby is corundum. Rubies are a variety of the mineral corundum that get their red color from trace amounts of chromium present in the crystal structure.
No, Ruby is not a type of crystal like quartz or amethyst. Ruby is a precious gemstone made of red corundum, a mineral form of aluminum oxide. It is prized for its deep red color and often used in jewelry.

Bauxite and corundum are both aluminum minerals. Bauxite is the primary ore of aluminum from which aluminum is extracted, while corundum is a naturally occurring crystal form of aluminum oxide known for its hardness and use in abrasives.
Corundum is transparent as a mineral, especially in its gemstone forms such as sapphire and ruby. The level of transparency can vary depending on the quality and any inclusions present in the crystal structure. In general, corundum is prized for its transparency and clarity when cut and polished as a gemstone.
THE EIGHT WAYS TO I.D. A MINERALThe eight ways to identify a mineral such as corundum are 1 hardness 2 crystal shape 3 special features 4 density 5 streak 6 luster 7 cleavage or fracture 8 color. (to find out hardness look up "Mohs scale of hardness" everything else you could search it on google or bing)

The smallest and most repetitive parts of crystals like fluorite and corundum are called unit cells. Unit cells are the basic building blocks that repeat in three dimensions to form the crystal lattice structure of the entire crystal.
Rubies come from the mineral corundum, which is a crystalline form of aluminum oxide. The red color in rubies is due to trace amounts of chromium present in the crystal structure of corundum.
