If theres pearl and mother of pearl, then there's more than 1.

Alas Ken, Mother-of-Pearl is formed on the inside of the shell, not in the body of the oyster. Most shellfish have a coloured, shiny layer on the inside of their shell, so it is pretty, but not prized as a gem-stone. Mother-of-pearl jewellery can be bought quite cheaply on most Mediterranean island sea-fronts.

Mother of pearl and abalone SHOULD be in this question. Leaving them out is unacceptable. Toss this question!

Agreed. There is abalone and Mother of Pearl. The question is worded badly and should be removed. I wish there was better vetting here.
