Jesus Fish Christian Christianity rock. This is an example of a rock you will receive. Rocks measure approx 2 - 2 3/4 inches high by approx 2 1/4 inches wide by approx 1 inch thick, but some could be smaller or larger. Some rocks could have imperfections on them... variations in colors, or irregular shapes, or even some slight chips; however, these imperfections show us how imperfect we are compare to the Lord. Your rock will come in a bag and each of my rocks always come with a free gift. If you would like a specific shape or size, please contact me prior to purchasing; however, most rocks will have approximate measurements to the size above.
