The name ruby comes from ruber, Latin for red, and describes the purest beauty of red imaginable.
The red color of ruby is caused by tiny
amounts of the element chromium. The best shade of red for ruby is often
given the name "pigeon blood red", but ruby can be any shade of
red up to almost pink.
Rubies have a famous place in science
and technology. The world's very first lasers were made using artificial
ruby crystals. They are still used for this purpose in certain
applications. Some ruby crystals show the fluorescence (actually
very short term phosphorescence) that makes a laser possible.
