Ivory vs. Bone: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 17, 2023
Ivory is dense, hard, white material from tusks and teeth of animals, while bone is a rigid organ forming a skeleton.
Key Differences
Ivory, sourced primarily from the tusks of elephants and the teeth of certain other mammals, is known for its fine texture, durability, and creamy white color. In contrast, bone, which makes up the skeletons of most vertebrates, has a more porous structure and is generally off-white.
The use of ivory has been prized throughout history for art and decorative items due to its smoothness and the ease with which it can be carved. Bone, while also used in crafting, is more commonly associated with practical tools or utensils, and lacks the premium status of ivory due to its more common occurrence and different aesthetic qualities.
Ivory's extraction, often linked to the endangerment of species, particularly elephants, has led to international bans and significant ethical concerns. However, bone, usually harvested from animals that are used for a variety of other purposes (like food), does not generally involve the same ethical implications, except in cases of endangered species.
When it comes to authenticity verification, ivory tends to be denser and has a specific crosshatch pattern, known as Schreger lines, visible in cross-section. Bone, however, shows a more porous, less dense structure under similar examination, which helps in distinguishing between the two materials.
In terms of maintenance, ivory, being more sensitive to environmental conditions, can crack or discolor over time and requires careful preservation. Bone is also susceptible to damage over time but is generally more resilient to environmental changes compared to ivory.
