These two pieces of Ivory are joined together to form the surface of one key because the material is brittle and more difficult to manufacture large pieces.

Ivory piano keys appear to have a pattern on the surface of the key that looks similar to the grain on a piece of wood.

Plastic Keytops

Plastic keys can be cleaned to near perfection without many blemishes and void of variances in the color.

The surface of the Ivorite key is less smooth and provides consistent friction which reflects less light when trying to see a reflection from the surface than in plastic piano keys.

The wear and tear you see below will not be the same from a piano that has Ivorite today, this is because the chemical composition of the material has seen significant technological advancements.

International trade ban on Ivory

Read about the ivory trade on Wikipedia: Ivory Trade

Pianos manufactured in Western countries discontinued the use of Ivory keys in the early 1970’s as ethical concerns began to arise, only a few decades before trade bans.

International trade bans have prohibited the sale of Ivory since 1989 and as a result, all modern pianos do not include Ivory due to ivory trade bans.

It’s much more common for antique pianos to have ivory keys because it was a preferred material to use for pianos, however it’s no longer legal to produce new pianos with ivory keys anymore.

Old Ivory keytops can be kept and saved for use on minor repair especially if it was required before the early 1980s, but cannot be directly sold as a raw material.

If the ivory keys on a piano are in good shape, it does not necessarily mean that it is worth a lot more, what’s more important is if it does not need additional key work to fix chipped keys which is costly.

Elephant tusks are where ivory keytops come from and is most commonly used for piano keytops.

Solid ivory is a cement dentine material similar to dental bone in that it is much more dense than regular bone.

Believe it or not, Elephants are an endangered species which is why it is critically important to continue the Ivory trade ban for all intents and purposes.
