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.
Hence, figuratively, something resembling a pearl; something very precious.

Pearl Harbor caused our Nation to wholeheartedly commit to winning World War II, changing the course of our Nation's history and the world's future. Joe Baca
History demonstrates that previous military drawdowns invited aggression by our enemies. After World War I, America drew down forces until the U.S. Army had fewer than 100,000 men in uniform. That weakness invited Nazi aggression in Europe and the imperial Japanese attack at Pearl Harbor. Frank Gaffney
Some calamities - the 1929 stock market crash, Pearl Harbor, 9/11 - have come like summer lightning, as bolts from the blue. The looming crisis of America's Ponzi entitlement structure is different. Driven by the demographics of an aging population, its causes, timing and scope are known. George Will
When reflecting upon it today, that the Pearl Harbor attack should have succeeded in achieving surprise seems a blessing from Heaven. It was clear that a great American fleet had been concentrated in Pearl Harbor, and we supposed that the state of alert would be very high. Hideki Tojo
Nothing is over until we decide it is! Was it over when the Germans bombed Pearl Harbor? Hell, no! John Belushi
