Rubies are part of the corundum mineral group.
Corundum is a mineral composed of aluminum oxide with traces of other elements that give it its various colors. It is commonly known for its gem varieties such as ruby and sapphire, which are prized for their beauty and hardness. Corundum is one of the hardest minerals, second only to diamond, making it ideal for use in various industrial applications.
Carbon and hydrogen are the two main elements that make up crude oil.
No, minerals are compounds made up of various elements. Elements are the simplest form of matter and cannot be broken down into simpler substances. Minerals are composed of specific combinations of elements that define their unique properties.
The elements that make up life include carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements are essential for building and sustaining living organisms.
100% of rubies are corundum. "Ruby" is a name made up by the gem trade for the mineral known as corundum, when it is red.
The mineral commonly used to make jewelry, decorative items, mechanical parts, and abrasives is corundum. Corundum is a crystalline form of aluminum oxide and is highly valued for its hardness, making it suitable for abrasive applications. Additionally, when corundum is colored by trace elements, it can form gemstones such as sapphires and rubies, which are widely used in jewelry.
Corundum is a crystalline form. This crystalline form is made up of aluminium oxide.
Carbon, hydrogen and oxygen are the only elements that make up sugars.
Corundum.
Some common items that contain corundum include sandpaper, grinding wheels, and some types of cutting tools. Corundum's hardness and toughness make it a popular material for abrasive applications.
Rubies are part of the corundum mineral group.
An abrasive material called emery is made up of corundum, which is a naturally occurring form of aluminum oxide. Corundum is a very hard mineral that is commonly used in abrasives for grinding, cutting, and polishing applications due to its durability and hardness.
Sapphire comes from the corundum mineral family, which is an aluminum oxide (Al2O3). Corundum consists of pure aluminum oxide, it also contains trace amounts of other elements such as iron, titanium and chromium.
Corundum can be transparent, depending on its quality and impurities present. High-quality corundum gemstones, such as sapphires and rubies, are usually transparent and highly valued. However, corundum can also contain impurities that make it opaque or translucent.

***Pure corundum is transparent and colorless but most specimens contain some transition elements substituting for aluminum, resulting in the presence of color. Substitution of Chromium results in a deep red color; such red corundum is known as ruby.corundum is a dark red, blue and yellow colors
