nacreous

It is seldom as much as half an inch in length, and has a nacreous interior.

It is an essentially beautiful and satisfying contribution to modern painting, this nacreous cubism of Marie Laurencin.

Two kinds of shell-substance are at once distinguishable in an oyster-shell, an outer brown, and an inner pearly or nacreous.

The interior is nacreous, and of a greenish colour, with a white patch round the columella.

Shell not nacreous, without umbilicus, with prominent spire and polished surface.
