Hi,
For the next few posts we will talk about a certain mineral.In this post we will talk about the mineral,ruby.A ruby is the second hardest mineral right before diamonds.Rubies can be red, purplish,pinkish, or brown.It's formula is AL2O3:Cr.It's streak is white.It's luster is Vitreous.It's melting point is at a wapking 2044oC

It is said that a ruby has a fire in it that never goes out.This makes it the symbol of love.That is why it makes a great ring.If worn on the left hand it will bring you happiness and joy.Some say it is the best of the 12 stones that were created by god.It is also said that if it changes color it means danger.Rubies are very similar to sapphires.They say the ruby is the king of gems.This jewel is most commonly used in rings and bracelets.
