What is the chemical name of Ruby Sapphire?
corundum
The Chemical Makeup Of Sapphires. Sapphires and rubies are corundum, which is an aluminum oxide (Al2O3.). Corundum has a regular crystalline structure formed by repeating patterns of arrangement at the atomic level.
What is the scientific name for ruby and sapphire?
A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). Other varieties of gem-quality corundum are called sapphires. The word ruby comes from ruber, Latin for red. The color of a ruby is due to the element chromium.
What chemicals make rubies?
Rubies are made of the mineral corundum, which is aluminium oxide. Pure corundum is clear, but a trace amount of chromium in rubies is enough to give them their characteristic red colour. All other types of corundum minerals are called sapphires and come in a variety of colours.
What are rubies and sapphires known as?
The three other types of precious stones – rubies, sapphires and emeralds – are all referred to as “colored stones”. Scientifically speaking, rubies and sapphires are the same mineral (corundum). Both are made of alumina and oxygen, but they just differ in color.
What is the Sapphire’s chemical composition?
aluminum oxide
Sapphire is a variety of corundum or aluminum oxide and Al203 gives its chemical formula—that is, two parts of Aluminum to three parts of Oxygen.
What mineral is topaz made of?
silicate mineral
Topaz (/ˈtoʊˌpæz/ TOH-paz) is a silicate mineral of aluminium and fluorine with the chemical formula Al2SiO4(F, OH)2. It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue, golden brown to yellow orange.

What is Topaz made of?
Topaz is an aluminum silicate containing fluorine and has a chemical formula of Al2(F,OH)2SiO4. It is formed by fluorine-bearing vapours given off during the last stages of the crystallization of igneous rocks. It typically occurs in cavities in rhyolites and granite, in pegmatite dikes, and in high-temperature veins.
What is a blue ruby?
Corundum is an aluminum oxide that commonly forms hexagonal barrel-shaped prisms that taper at both ends or as thin tabular hexagonal plates. Red corundum is called ruby, blue corundum is called sapphire, and all other colours are called fancy sapphires.

How are rubies and sapphires the same colour?
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.
Is the mineral corundum the same as the Ruby?
Both of these gemstones have the same chemical composition and the same mineral structure. Trace amounts of impurities determine if a gem corundum will be a brilliant red ruby or a beautiful blue sapphire. It is surprising that “impurities” can produce such wonderful results!
Where can you find Sapphire and Ruby in Australia?
The basaltic, volcanic rocks in Eastern Australia are a major source of corundum, sapphire and ruby, however, the minerals are rare and not commonly mined directly from these rocks. This is because it is very expensive to extract small gems from hard rock and many of them are broken during mining.
