- Ivory - Ivory is a hard white material that comes from the tusks of elephants, mammoth, walrus and boar, or from the teeth of hippopotamus and whales. The ivory from the African elephant is the most prized source of ivory. Although the mammoth is extinct, tusks are still being unearthed in Russia and offered for sale.
Ivory has been used since the earliest times as a material for sculpture of small items, both in Europe and the east, principally China and Japan.
In Asia ivory has been carved for netsuke, seals, okimono, card cases, fan supports, animals and other figures and even as carved tusks.
In the last 200 years in Europe ivory has been used to carve figures, for elaborate tankards, snuff boxes, cane handles, embroidery and sewing accessories, in jewellery and as inlay on furniture. Its more practical uses include being used for billiard balls, buttons, and a veneers on the top of piano keys.

Under Appendix One, international trade in Asian or African elephant ivory between member countries is forbidden. Unlike trade in elephant tusks, trade in mammoth tusks is legal.
Since the invention of plastics, there have been many attempts to create an artificial ivory
- Mother-Of-Pearl - Mother-of-pearl, technical name "nacre", is the inner layer of a sea shell. The iridescent colours and strength of this material were widely used in the nineteenth century as an inlay in jewellery, furniture, (especially papier mache furniture) and musical instruments.
In the early 1900s it was used to make pearl buttons. Mother-of-pearl is a soft material that is easily cut or engraved.
Nowadays it is a by-product of the oyster, freshwater pearl mussel and abalone industries.
