Spiritual Meaning:
The necklace is an acknowledgement of honour and power. Prayer beads strung together are found in most religions to help with the recitations of devotions and prayers.

Psychological / Emotional Perspective:
Necklaces first arose from the wearing of a chain of office and, therefore, in dreams suggests a dignity or honour that has been conferred on the wearer. The composition of the necklace may be an important part of the interpretation of the dream.

Everyday Material Aspects:
A necklace suggests a special object, and thus translates into special qualities or attributes. There is a richness to be acknowledged. This may be of feeling or of emotion. An old interpretation of a man giving a woman a necklace was that he would soon ask for her hand in marriage.
