explanations are simplified and concise enabling you to quickly learn how

Pearls
A pearl is an organic gem that comes from a living thing. It is produced
when an irritant finds its way into the oyster's shell and lodges itself
inside. The oyster secretes layers of conchiolin and nacre to form a lustrous
pearl. Out of 10,000 oysters, one might produce a natural pearl. Because of
their rarity, the Japanese have perfected a culturing process that implants
starter beads in the oysters and then the oysters are cared for and
nurtured for 2-4 years. Pollution, inclement weather, and disease cause a high
mortality rate resulting in sporadic annual harvests and accompanying shortages
of larger sizes and higher qualities.
Cultured pearl values are determined by five factors: color, luster, shape,
surface quality, and size. Varieties include saltwater Akoya, Tahitian, South
Sea, and freshwater.
Gemstones
There are five essential characteristics of gemstone quality. These
characteristics combined with rarity, durability, and beauty determine the
value of all gemstones. A better understanding of these technical aspects will
greatly assist you in making the best choice when shopping for the best value
in gemstone jewelry.
Gold & Platinum
Gold and platinum are among the world's most precious metals. They combine four
basic characteristics that have made them treasured possessions since earliest
of times: lustrous beauty, easy workability, rarity, and virtual
indestructibility.
