These bone vertebra are approximately 5/8 to 1 inch wide and 1/4 to 1/2 inch tall. They have an antique off white color and each one has natural sets of ridges and ‘knot holes’ along the edge. They are very light weight, a similar feeling to balsa wood, technically they are considered to be calcified cartilage. Photos are stock photos, you will not receive these exact vertebrae but ones very similar. These vertebra would be especially great for use in a necklace, bracelet, earrings, or other jewelry. These vertebrae come from sharks that were used for food. Out of country buyers, my apologies but due to US export law, I cannot ship wild animal product out of country.
