The Coat-of-Arms of Archbishop Yllana was designed by Cardinal Andrea de Montezemolo. The colors in the four parts indicate the faith (blue) as the beginning of grace coming from God and pervades everything, to which the human will responds to (silver) in the practice of the virtues.

• The star indicates the light of sanctifying grace;
• The rose represents the Virgin Mary, mother and help of all Christians (here the rose represents Our Lady of Peñafrancia, the patroness of the Bicol region, to whom the archbishop-elect, just like every Bicolano, has a special devotion and attachment);
• The undulating waves indicate water, which penetrates everywhere it passes making life flourish, as the pastoral work of the archbishop-elect is indicated in the motto "to Preach (proclaim the Gospel, announce the Good News or evangelize) and to Serve".
• The book indicates the Gospel, as the word of God, which inspires, teaches and guides every action of life, be it in evangelizing as in serving.
