Rubies
What are Rubies?
Rubies are over 500 million years old and rank among the world’s most precious gemstones – large natural rubies frequently cost more per carat than colourless diamonds.
The word ruby comes from ruber, Latin for red. Rubies vary in colour from purplish red to orangy red. Rubies and sapphires share the same characteristics, crystal structure and chemical composition. They only differ in the trace element, chromium, from which rubies get their colour.
