The cross is the first example of jewelry made in the Kingdom of Asturias that has reached our days. Its current appearance is the result of careful reconstruction carried out after the damages the cross underwent in August 1977 after the robbery of the Camara Santa . Its squared dimensions (46.5 centimetres (18.3 in), 45.7 centimetres (18.0 in) wide and 2.5 centimetres (0.98 in) thick) are typical from Greek crosses. The cross is formed by two pieces of cedar wood with, at the center, a round disc.

The Cross of the Angels became the symbol of the city of Oviedo around the 15th century, although it is said that even earlier, in 1262, it was used as a seal of the city. This is reflected in an engraving in the old city walls where the cross, with the Greek letters alpha and omega hanging of his arms, is used as a sign of consecration. Nowadays, the cross is present in the coat of arms of both the city of Oviedo and the Roman Catholic Archdiocese of Oviedo.
