The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. Ruby is the red variety of corundum, the second hardest natural mineral known to antiquity. Ruby Mineral Facts:. Its red color results when chromic ions (Cr 3+ ) replace some of the aluminum ions in the crystal. The brightest and most valuable shade of red called blood-red or pigeon blood, commands a large premium over other rubies of similar quality. Chemical formulas such as \(\ce{HClO4}\) can be divided into empirical formula, molecular formula, and structural formula. Rubies are also used in applications where high hardness is required such as at wear-exposed locations in modern mechanical clockworks, or as scanning probe tips in a coordinate measuring machine. A perfectly translucent Ruby is rare. However, even here these properties depend on the way the atoms are bound in the mineral's crystal structure. Different solutions and mixes have shown to be successful, however mostly lead-containing glass-powder is used at present. Sapphire, ruby, and pure corundum are α-alumina, the most stable form of Al2O3, in which 3 electrons leave each aluminium ion to join the regular octahedral group of six nearby O2− ions; in pure corundum this leaves all of the aluminium ions with a very stable configuration of no unpaired electrons or unfilled energy levels, and the crystal is perfectly colorless. These heat treatments typically occur around temperatures of 1800 °C (3300 °F). Chemical Formula: Al 2 O 3 The mineral is nearly always a practically pure oxide of aluminum of the composition Al 2 O 3, in which there are 52.9 per cent Al and 47.1 percent O.The impure varieties usually contain some iron, mainly as an admixture in the form of magnetite. The basic chemical formula of corundum is AL2O3 (aluminum oxide). Ruby, Sapphire, and Fancy Sapphire. Ruby is the traditional birthstone for July and is usually pinker than garnet, although some rhodolite garnets have a similar pinkish hue to most rubies.
