Necklace was made with a real mustard seed in resin. Each necklace comes with a note about the history and signficance of the mustard seed (text below).
THE MUSTARD SEED:
The mustard seed is a symbol of faith and luck. Mustard seed necklaces were first popular in Victorian times. Then in the '40s and '50s, they became popular again as good luck charms.
The mustard seed is used in the Bible as a reminder that even a little faith can move mountains.
". . . if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; nothing will be impossible for you.”
