The present value of pearls—which has advanced enormously since 1893—is due to the extended markets and the increased wealth and fashion in Western countries, rather than to diminished fisheries. The oriental demand still consumes the bulk of the Persian and Indian output, and the vast increase in wealth among the middle classes in America, Europe, and elsewhere, has increased the demand tenfold over that of a century ago. While women no longer appear ornamented from head to foot as in the sixteenth century, pearls are in the highest fashion, and the woman of rank and wealth usually prizes first among her jewels her necklace of pearls.

ORIGIN OF PEARLS

ssss1

Heaven-born and cradled in the deep blue sea, it is the purest of gems and the most precious.

S. M. Zwemer.

The origin of pearls has been a fruitful subject of speculation and discussion among naturalists of all ages, and has provoked many curious explanations. Most of the early views—universally accepted during those centuries when tradition had more influence than observation and experiment—have no standing among naturalists at the present time. And although much information has been gained as to the conditions accompanying their growth, and many theories are entertained, each with some basis in observed fact, science does not yet speak with conclusive and unquestioned authority as to the precise manner of their origin and development.
