The mitre is decorated with enamel panels containing portraits of the three-figured Deesis, the guardian angel, St. Zachary and St. Elizabeth, St. Sergei of Radonezh, and the Patriarch Nikon. St. Elizabeth was the patron saint of the empress, while Sergei and Nikon were the founders of the Troistse-Sergiev Monastery. The Trinity is portrayed on a lozenge-shaped panel in the center of the mitre.
The mitre is made of gold brocade. It is decorated with sparkling brilliant-cut diamonds and rubies and smooth, carefully selected pearls. It was clearly a royal endowment, the work of the finest court craftsmen. It is therefore not surprising that the mitre includes pearl-embroidered images of the two-headed eagle under a crown with an orb and sceptre in its claws -- the state emblem of Russia.
