A ruby is a pink-ish red to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). Ruby is one of the most popular traditional jewelry gems and is very durable. Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, alongside amethyst, sapphire, emerald, and diamond.^[3] The word ruby comes from ruber, Latin for red. The color of a ruby is due to the element chromium.
Some gemstones that are popularly or historically called rubies, such as the Black Prince's Ruby in the British Imperial State Crown, are actually spinels. These were once known as "Balas rubies".
The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. The brightest and most valuable shade of 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. Ruby is the traditional birthstone for July and is usually pinker than garnet, although some rhodolite garnets have a similar pinkish hue to most rubies. The world's most valuable ruby to be sold at auction is the Sunrise Ruby.

The Black Prince's Ruby dates back to the middle of the 14th century as the possession of Abū Sa'īd, the Arab Muslim Prince of Granada. At that time, the rule of Castile was being centralized to Seville and the Moorish Kingdom of Granada was being systematically attacked and reverted to Castilian rule as a part of the Christian Reconquest of the Iberian peninsula. Abū Sa'īd in particular was confronted by the belligerency of nascent Castile under the rule of Peter of Castile, also known to history as Don Pedro the Cruel. According to historical accounts, Abū Sa'īd wished to surrender to Don Pedro, but the conditions he offered were unclear. What is clear is that Don Pedro welcomed his coming to Seville. It is recorded that he greatly desired Abū Sa'īd's wealth. When Abū Sa'īd met with Don Pedro, the King had Abū Sa'īd's servants killed and may have personally stabbed Sa'īd to death himself. When Sa'īd's corpse was searched, the spinel was found and added to Don Pedro's possessions.
In 1366, Don Pedro's illegitimate brother, Henry of Trastámara, led a revolt against Don Pedro. Lacking the power to put down the revolt unaided, Don Pedro made an alliance with the Black Prince, the son of Edward III of England. The revolt was successfully put down and the Black Prince demanded the ruby in exchange for the services he had rendered. He later returned to England with King Pedro's two daughters, Dona Constanza of Castile and Dona Isabel of Castile, and marriages were contracted for them to the king's brothers. It is assumed that the Black Prince took the Ruby back to England at that time, although it disppears from historical records until 1415.

During his campaign in France, Henry V of England wore a gem-encrusted helmet that included the Black Prince's Ruby.^[7] In the Battle of Agincourt on 25 October 1415, the French Duke of Alençon struck Henry on the head with a battleaxe, and Henry nearly lost both the helmet and his life. The battle was won by Henry's forces and the Black Prince's Ruby was saved. Richard III is supposed to have worn the gemstone in his helmet at the Battle of Bosworth, where he died.
