means The legendary entrance to heaven, imagined as glistening gates where souls are judged worthy of admission.

from Rooted in the Book of Revelation, which describes the heavenly city of New Jerusalem as having twelve gates made of twelve pearls, each gate a single, massive pearl. Pearls, prized since antiquity as rare treasures pulled from the sea, became shorthand for otherworldly splendor — something too perfect for ordinary hands. The image of Saint Peter standing guard there is a later folk addition, built from his role as keeper of 'the keys to the kingdom of heaven' in the Gospel of Matthew, rather than anything stated outright in scripture.
