A shelly concretion, usually rounded, and having a brilliant luster, with varying tints, found in the mantle, or between the mantle and shell, of certain bivalve mollusks, especially in the pearl oysters and river mussels, and sometimes in certain univalves. It is usually due to a secretion of shelly substance around some irritating foreign particle. Its substance is the same as nacre, or mother-of-pearl. Pearls which are round, or nearly round, and of fine luster, are highly esteemed as jewels, and compare in value with the precious stones.

That weakness invited Nazi aggression in Europe and the imperial Japanese attack at Pearl Harbor. Frank Gaffney
I would prefer to live forever in perfect health, but if I must at some time leave this life, I would like to do so ensconced on a chaise longue, perfumed, wearing a velvet robe and pearl earrings, with a flute of champagne beside me and having just discovered the answer to the last problem in a British cryptic crossword.
