We usually used Sapphire as synonymous of blue colour.sapphire is beautiful beyond blue, in every colour but red, red being the domain of the ruby.
Sapphire others colours are just as beautiful and rare than the blue but they are usually offered at more modest prices. Yellow, orange, lavender, and other pastel shades are especially affordable.
Not realising that ruby and sapphire were actually the same mineral, our ancestors left us with a dilemma: how should pink shades be classified? Long ago, it was decided that all gemstones of the mineral corundum should be referred to as sapphire, except the red colour, which was called ruby.
But Pink is really just light red. The International Colored Gemstone Association has passed a resolution that the light shades of red should be included in the category ruby, since it is too difficult to legislate where red ends and pink begins. In practice, pink shades are now known either as pink ruby or pink sapphire. Either way, these gems are among the most beautiful of the corundum family.
