What kind of dinosaur is ruby from the land before time?
Ruby is an Oviraptor.
What is the chemical symbol of the ruby?
Ruby is a form of the mineral corundum, which has the formula Al2O3.
A ruby is a natural gem?
A ruby is a naturally occurring crystal of the mineral corundum. Rubies can also be created in laboratory settings as well. The chemical composition and crystalline structure is identical.
Properties of a ruby?
The chemical composition of ruby is aluminum oxide (Al 2 O3). Its specific gravity is 3.99 to 4.00 and refractive index range is 1.760-1.768 to 1.770-1.779. Ruby's hardness on Mohs scale is 9. It's the next hardest mineral after diamond.
Chemical equation for gemstone?
Gemstones are naturally-occurring minerals and do not have a specific chemical equation like a chemical reaction would. However, they can be described chemically based on their mineral composition. For example, the chemical formula for quartz, a common gemstone, is SiO2.
What is the composition of a ruby?
Ruby is the name given to red corundum, which is a mineral composed of aluminum and oxygen.
How dense is a ruby?
The density of a ruby varies depending on the specific composition and quality, but on average it ranges from 3.9 to 4.1 g/cm^3.
What is the chemical composition to a ruby?
The chemical composition of ruby is aluminum oxide (Al 2 O3). Its specific gravity is 3.99 to 4.00 and refractive index range is 1.760-1.768 to 1.770-1.779. Ruby's hardness on Mohs scale is 9. It's the next hardest mineral after diamond.
What is the chemical composition of garnet?
Garnet is a group of silicate minerals with the general formula X3Y2(SiO4)3, where X can be calcium, magnesium, ferrous iron, or manganese, and Y can be aluminum, ferric iron, or chromium. This composition gives different garnet species their unique colors and properties.
Why might it be important for a mineralogist to distingish between a ruby and a garnet?
They are two completely different stones to start with. While there are garnets that have a deep red color it has more of a brown cast to it and, owing to its chemical composition being mainly silicon and oxygen, is softer than ruby. While Garnet is used in jewelry it is a semi-precious stone. Ruby's chemical structure is based on aluminum an oxygen and ranks 9 on Moh's Hardness scale, just under diamond. Ruby is classed as a precious stone and, depending on the quality, may cost as much as diamond. Short answer is, if a mineralogist mistook garnet for ruby or ruby for garnet, and was verifying a sale, he could cause a loss of money on either side.
What is the refractive index of ruby?
The refractive index of ruby is typically around 1.76 - 1.77. This value may slightly vary depending on factors such as the composition and quality of the specific ruby sample being measured.
What is synthetic ruby?
Ruby's chemical make up is AL2O3:CR, that means that every molecule in it has 2 atoms of aluminum, 3 atoms of oxygen connected to an atom of chromium. In the 1800's chemists figured out that by combining aluminum oxide with chromium at high heat they would get synthetic ruby. The process has been modified through the years but, chemically speaking, synthetic ruby is the same as natural ruby. From a retail point of view they are worlds apart and man-made stones must be marked as such and cannot be sold as ruby.
What chemical element make up ruby red?
Ruby is not a chemical compound and so does not have a precise chemical structure. It consists mainly of Aluminium Oxide Al2O3, and also contains chromium which gives ruby its characteristic red or reddish brown tint.
