Encased and preserved in this delicate half-circle brass frame is a single real mustard seed. This necklace is classic and elegant. It serves as a meaningful reminder that even our tiny steps of faith can move mountains. The mustard seed is known as a symbol of faith. “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; and nothing will be impossible to you.” Matthew 17:20 Chain is gold plated brass. Materials are tarnish resistant. The symbolism of the botanical is printed on a tag that is attached to your jewelry.
