Chemical equation for gemstone?
Gemstones are minerals and compounds found in nature, and they do not have specific chemical equations associated with them. However, I can provide you with examples of chemical compositions for some well-known gemstones: Diamond: The chemical composition of a diamond is pure carbon (C). Ruby: Rubies are a variety of corundum with a deep red color due to the presence of chromium (Cr). The chemical formula for ruby is Al2O3:Cr. Sapphire: Sapphires are also a type of corundum but can come in various colors. The blue color in sapphires is often attributed to the presence of iron (Fe) and titanium (Ti). The chemical formula for blue sapphire is Al2O3:Fe, Ti. Emerald: Emeralds are a type of beryl with a green color that is primarily due to the presence of chromium (Cr) and sometimes vanadium (V). The chemical formula for emerald is Be3Al2(SiO3)6:Cr, V. Amethyst: Amethyst is a variety of quartz (silicon dioxide, SiO2) that exhibits a purple color due to impurities of iron (Fe) and aluminum (Al). These examples highlight the chemical components that contribute to the distinct colors of these gemstones. Keep in mind that gemstones can have varying compositions and impurities, resulting in a range of colors and properties.
Are rubies used in electronics?
Yes, rubies are used in some LASERs. These LASERs are (not surprisingly) called ruby LASERs.
Rubies and Sapphires are chemically known as?
Aluminium oxide and Corrundum
What is the compositon of ruby?
The main component of rubies is the mineral corundum.
How do rubies get their color?
The red color is caused mainly by the presence of the element Chromium.
Why are rubies red and sapphires blue?
Both rubies and sapphires are made of corundum (aluminum oxide) which is colorless on its own. Ruby is made red by trace impurities of chromium. Sapphire is made blue by titanium and iron. However, sapphire does not have to be blue. Any gem-quality corundum crystal that is not red is considered sapphire.
What metal impurity makes rubies red and emeralds green?
Chromium plus corundum = ruby, chromium + beryl = emerald.
What is the composition of chromium oxide and aluminium oxide in ruby?
Ruby is aluminium oxide; chromium is only a natural dopant, in traces. The concentration of chromium is not constant in rubies.
Tiny amounts of what element cause rubies to be red?
That element is called chromium.

What are some special characteristics of a ruby?
Rubies are a type of corundum mineral, known for their vibrant red color, which is caused by the presence of chromium. They are one of the hardest gemstones, measuring 9 on the Mohs scale, making them very durable for everyday wear. Rubies are also believed to symbolize love, passion, and vitality, making them a popular choice for engagement rings and special occasions.
Why rubies and sapphires different colors?
Ruby owes its red color to Chromium and sapphire to Titanium and Iron (charge transfer concept)
What is ruby made of?

Ruby a mineral or a rock?
Rubies (and sapphires also) are compounds of a crystallized mineral called corundum that consists mostly of aluminum oxide (Al2O3).
Why are saphires and rubies different colors?
because of different internal chemical composition .
