Ruby

A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. Ruby is considered one of the four precious stones, together with sapphire, emerald and diamond.

Prices of rubies are primarily determined by color.The brightest and most valuable "red" called blood-red or "pigeon blood", commands a large premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Cut and carat (weight) are also an important factor in determining the price. Ruby is the traditional birthstone for July and is always lighter red or pink than garnet. The world's most expensive ruby is the Sunrise Ruby.

Max & Ruby

Max & Ruby is a 2002 Canadian-American animated series that is aimed at preschoolers. Created by children's book author/illustrator Rosemary Wells and based on the world of her Max and Ruby books, the episodes present stories about Max, a rambunctious and determined preschool-aged rabbit, and his older sister, Ruby, a patient, goal-oriented, sometimes restrictive rabbit. A pilot episode for this series aired in 2001 and the program appeared as a regular series on October 3, 2002. According to Rosemary Wells on the Nick Jr. website, "Max & Ruby celebrates the relationship between Ruby and her younger brother, Max, and the universal nature of sibling relationships."

Rosemary Wells, the author of the children's books the show is based on, says: "We don't see Max and Ruby's parents because I believe that kids resolve their issues and conflicts differently when they're on their own. The television series gives kids a sense about how these two siblings resolve their conflicts in a humorous and entertaining way." For the first season, Jamie Whitney was the director, and the first episodes were mostly written by Kate Barris and Patrick Granleese. While some of the stories were adapted from the books, the number of TV episodes eventually surpassed the number of books written by Wells.
