Red Crystals are commonly known as Ruby's, they are formed in the chimney of volcanoes after eruptions and are very valuable.

A single twenty-four carat ruby is worth twenty-seven thousand pounds.

Ruby's where also used by the Greeks to show there feelings two each other; as were all different coloured crystals.
That is a very expensive red crystal.
