Ruby is the red color in the mineral family corundum. The rest of the colors of corundum are termed as sapphires like blue sapphire, pink sapphire or yellow sapphire but if the major color is red of whole body it is then called a ruby stone.
A lighter color ruby is a pink sapphire. Though there is no fixed globally ascertained line which distinguishes the color of ruby and a pink sapphire or how much the color red should be there to make the pink sapphire stone to go in the ruby stone category. What is seen in the certifications of globally recognised labs like GIA, IGI or Gubelin and GRS is a visible red color should be there.
Al2O3 is the mineral species corundum where all.sapphires belong to. The chromium present in corundum is responsible for the color in corundum and amount of chromium present is ruby is more then that in pink sapphire so that distinguishes a pink sapphire from a ruby. A pink sapphire may even be more saturated and vibrant with more color present then some ruby, so they need to be differentiated on basis of color as pink is pink sapphire and for ruby the red color should be seen.
Heat is the most common treatment in ruby gemstone. Were the ruby goes through a thermal enhancement process in a furnace in controlled manner to enhance its appearance. Heat is a commonly accepted treatment in ruby gemstone. On other hand unheated and untreated ruby gems are those which are in their 100% original form as they were when extracted and just cut and polished to be beautiful gemstones with no alteration to their structure or flaws.
Ruby transparency and inclusions
Natural ruby in clear transparency is a very rare stone. Rubies generally come filled with inclusions, much more then any sapphire or emerald minerals found in natural state. Even a 2 carat ruby which has good red color is rare to be free of inclusion so inclusions are accepted well in this precious gemstone.
Opaque rubies do not fall in gem category and are very cheap but if there is transparency and luster in the stone it demands high prices irrespective of minor to moderate inclusions.
