The Crown of Thorns is an enduring Christian symbol of the Passion of Christ. His was the ultimate sacrifice and he was mocked by the soldiers as "The King of the Jews" as they led him to the cross.
Keep this silvery crown in your pocket as a reminder of faith. How about adding it to a necklace, or creating one with a simple chain? Its design lends itself easily to artwork and shrines. You might even add a ribbon and turn it into a bookmark, maybe to keep your place in the Bible.
It measures 7/8 inch in diameter (about 23 mm).
