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,

. 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 disappears from historical records until 1415.
