The blue sapphire is a gem of the corundum family. Sometimes white sapphires, rubies, and blue sapphires are found in the same mine, and that is why there is a mixture of colors in the crystals of these gems. Ruby is harder than white sapphire (known as pukhraj), and blue sapphire is harder than ruby and it is hardest of all.
