Eland bone are both hard, white materials. However, there are a few key differences between the two that you can use to tell them apart. One of the most obvious differences is the texture of the surface. Ivory is smooth and polished, while bone is more porous and has a matte finish. Additionally, ivory is more flexible than bone, so it can be bent without breaking easily.
Another difference between ivory and bone is the color. Ivory is typically a creamy white color, while bone is more yellow or brown. The color of ivory can also vary depending on the age of the animal from which it came. Older ivory is more yellowed than newer ivory.
