Ruby
Ruby belongs to the Corundum mineral family. The red variety of Corundum is known as Ruby, while other coloured stones in that family are known as Sapphire.
Although we think of Ruby red as a deep red colour, rubies can be any shade of red right through to a pink shade. The redness of a ruby depends on the chromium and iron content of the stone.
Although this type of gemstone is hard and durable, care should be taken to avoid fracturing or chipping rubies.
