This symbol represents the blessing of the Moon Goddess, and the three teardrops represent the triple aspect of the goddess: Maiden, Mother, and Crone.
According to the Triple Goddess concept, the three roles represent youth and innocence (Maiden), maturity and motherhood (Woman), and wisdom and the later stage of life (Crone). This completely aligns with the triple aspect symbolized by the three teardrops mentioned in the question.
