How Sapphires Are Formed Sciencing
Sapphires form when molten rock deep underground starts to cool down after an episode of volcanism or tectonic deformation (metamorphism). This happens very slowly, over millions of years, since the magma body is well insulated by the surrounding rock and stays at an extremely high temperature for a long time. It's also under tremendous pressure.
Tracing the Origin of Sapphire Gemstones Creation & Formation
Sapphires are usually formed when limestone and other metamorphic rocks are forced to crystallize under conditions of extreme heat. Moreover, these rocks usually need to contain large volumes of aluminum. Sapphires are formed during the process of aluminum-laden limestone crystallization. In rubies and sapphires, color is explained by crystal.

Answer 1: Sapphire is the name for the mineral corundum when it is blue in color. Minerals are composed of atoms of certain elements in certain arrangements. Corundum is made of aluminum and oxygen, and can be blue when the element titanium is incorporated into its atomic structure.

Sapphire is a precious gemstone that is a variety of the mineral corundum, which is composed of aluminum oxide. It is typically blue in color, but can also be found in other hues such as yellow, pink, purple, green, and colorless. The blue color of sapphire is due to the presence of trace amounts of iron and titanium in the crystal structure.
What are LabGrown Sapphires? International Gem Society
Introduction Sapphires and rubies are both gem varieties of the mineral corundum. They have the same chemical composition and structure. Gems generally get their colour because of certain metals or impurities contained in the mineral. The impurities in corundum gems produce the large range of colours found.

Geologic Formation Sapphires, like any naturally occurring gemstone, are formed by the different shifts, mixings and chemical changes that are constantly taking place in the earth. Then, Sapphire gemstones are created through certain shifts in heat and pressure and can be found in both metamorphic and igneous rocks.
How Are Sapphires Formed?
Structurally, the sapphire is formed in a hexagonal bipyramid. When mined, sapphires are typically found in a barrel shape due to the way that they form. Almost all sapphires have inclusions. During the formation of a sapphire rutile inclusions can form. These rutile inclusions look like small crystalline growths inside of the sapphire.
