Pearl - White
The pearl! What images it conjures. White-winged trading schooners, swaying palm trees and beautiful island maidens. To a degree, at least all of this is
- or was - true. However, there is much more to the pearl than this nineteenth century image.
The history of the pearl goes back thousands of years and it occupies several unique niches. For one thing, the pearl is the only gem that is used as it is found. While other gems require cutting and polishing before they can be used, the pearl requires no such work. Also, the pearl is in a special class known as organic gems. In addition to pearls, this class also includes certain corals, amber and, to a lesser degree, such materials as ivory and even tortoise shell.
The history of pearls credits them with magical properties as well as their value in the gem world.
Of course, we all know how Cleopatra dissolved a pearl in wine, then drank it. Though one may wonder what type of wine was strong enough to dissolve a pearl, other persons greatly supported the curative powers of the pearl.
In 1602, Italian physician, Arnobio, in his "Tesoro delle Gioie" gives a recipe containing thirty-four ingredients, including pearl, which he affirms will cure
"all the ills that flesh is heir to." Fortunately, for gem lovers everywhere, the pearl is appreciated far more for its beauty than for any curative powers.
Today, the natural pearl is almost unknown, its place having been taken by the cultured pearl pioneered in the 1890's by Kokichi Mikimoto. The rise of the cultured pearl industry gives the buyer the advantage of being able to choose the size, color and quality of the pearls they purchase.
In ancient days, it was believed pearls were ruled by the planet Venus, making them the ideal gift of love.
