A lovely old Victorian belief held that the mustard seed symbolized faith. For this reason, the small golden seed was encased in glass and worn as an amulet. This sterling silver replica of an antique pendant is inscribed on the back with an excerpt from the Bible that reads, "If you have faith as a grain of mustard seed... nothing shall be impossible unto you." Matthew 17.20. 18" with 1/2" pendant. Sterling chain.
