Ruby is the red-colored stone in the corundum mineral family. 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 on the body it is then called a ruby stone.
The lighter color of ruby is a pink sapphire. Though there is no fixed globally ascertained line which distinguishes the color of ruby and pink sapphire or how much reddish colour there should be to make the pink sapphire stone go in the ruby stone category. What is seen in the certifications of globally recognized labs, like GIA, IGI or Gubelin and GRS is a visible red color should be there to qualify the corundum for being a ruby.
Purple red is another confusion where the gemologist needs to see properly the presence of visible red color for the corundum to be a purplish red ruby or it goes for a purple sapphire certificate if not much red is visible.
Al2O3 is the mineral species corundum, which all sapphires belong to. The chromium present in corundum is responsible for the color. The amount of chromium present in a ruby is more than that in a pink sapphire, so that distinguishes a pink sapphire from a ruby. A pink sapphire can even be more color saturated and vibrant than some rubies, so they need to be differentiated on the 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 gemstones. Where the ruby goes through a thermal enhancement process in a furnace in a controlled manner to enhance its appearance. Heat is a commonly accepted treatment in ruby gemstones. On the 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.
The natural ruby in clear transparency is a very rare stone. Rubies generally come filled with inclusions, much more than any sapphire or emerald minerals found in their natural state. Even a 2-carat ruby which has a 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 the 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.
