- At the top, two vert bay leaf garlands are extended under books, tied by a silver and gules lace.
- Over the axis, in the fashion of a pediment, a gules strip appears with the legend: UNIVERSIDAD AUTÓNOMA DE COAHUILA.
- As the base of the shield, an “asleep” sable eagle can be found, sustaining in its powerful claws the motto of the university with a gold lace.
- Shape of the shield: Spanish, masculine, traditional of states, kingdoms and sovereign institutions.
- Field: simple, because it only has one tincture on which the coat of arms of the university appears.
- Tinctures: gold, silver, blue, gules (red), vert (green), sable (black).
- The heraldic tradition pointed the next the moral attributes symbolized by these colors and tinctures:
- Gold means perseverance, faith and pureness, among others; those who have it on their shield are compelled to do good and to defend their nation “fighting for it until they have spilled the last drop of their blood”.
- Silver mandates to protect the weak and symbolizes pureness.
- Gules talks about value, boldness and fearlessness; those who wear it are forced to help the unfairly oppressed.
- Blue is the symbol of serenity, beauty and majesty, and those who have it on their shield are entrusted to assist the faithful servants of princes, which for us means to serve the Republic.
- Vert symbolizes freedom, hope and abundance; and compels those who use it to help the oppressed and the unprotected.
- And finally, the sable of the eagle which sustains the shield is the emblem of science.
