What does the moonstone symbolize?

The Moonstone stands, in the first place, as a symbol for the exoticness, impenetrability, and dark mysticism of the East—Gabriel remarks that the stone "seemed unfathomable as the heavens themselves" and "shone awfully out of the depths of its own brightness, with a moony gleam, in the dark." In the second place, the Moonstone is associated with femininity and even feminine virginity, through its associations with the moon and with pricelessness. The theft of the Moonstone from Rachel Verinder's bedroom by her nearly betrothed, Franklin Blake, can be read as a metaphor for her deflowering.
