As a rule, an oklad covers up the entire icon, with the exception of several parts, such as faces, hands, and feet. An oklad is more than a decoration and a shield against sunlight and mechanical damage. It symbolizes one's gratitude to Jesus Christ, the Mother of God, or the saint for their help. Each material used for making an oklad has its symbolic meaning: gold symbolizes God's grace, silver stands for purity of the soul and holiness, whereas gems point at spiritual virtues.
