"Faith as small as a mustard seed..." Let this dainty real mustard seed necklace be a reminder of this Biblical passage. I pour 3 thin layers of acrylic resin in the sterling silver or gold-filled frames and a real mustard seed lies within. The charms hang on a sterling silver or gold-filled chain with spring ring clasp. The mustard seed charm measures about 11mm in diameter. With proper care, this timeless piece of jewelry can last for years to come. Mustard seed placement may vary inside frame. While I do my best to avoid bubbles in the resin curing process, tiny bubbles may occur. Necklace comes packaged in a soft, reusable drawstring bag. Free NIV Matthew 17:20 Bible verse card included. Model is wearing a 17-inch chain in pictures. Complimentary polishing pad is included, which works like magic to bring jewelry back to life if it's not looking its best over time. Gently rub it on the gold or silver parts of the necklace and pendant piece but be sure to avoid rubbing the clear resin part of the charm.
