nacre

The floor was made of mats woven from strips of shell-nacre, bound at the sides with an inch border of pink coral.

The specimens collected by Mr. Schoolcraft, vary much in the color of the nacre.

He lifted a small hammer and struck a velvet-voiced bell that stood on the Arabian table of cedar inlaid with nacre and ivory.

Purplish bivalves and enormous nacre-lined conch shells lay upon the tables.

In the lower part is a dark clay with Pholadomya margaritacea, still preserving the pearly nacre.
