Coral occurs in a variety of colors -- white, pink,
orange, red, and black. The rarest, and most
expensive, is blood coral, also called noble or
oxblood coral. Another popular variety is the
blush pink angel skin coral used in fine jewelry.
Coral was widely believed to have medicinal and
mystical powers. Even today, coral powder is a
popular aphrodisiac in India. It was long
considered the most potent of all gems for
averting the 'Evil Eye'. The Romans hung coral
beads on their babies' cradles; later the toddlers
were required to wear them around their necks.
Coral warned its owners of impending illness or
poison. It was also seen as an aid to fertility. And,
coral is supposed to promote healthy feet; ft's
considered the good luck gem of the ballet.
Coral should be simply wiped with a clean, soft
cloth. Do not use a home ultrasonic machine or
jewelry cleaners. It is sensitive to chemicals,
detergents, perfumes, and body acids. Protect ft
from scratches, sharp blows and heat.
As part of the fashioning process, some coral is
bleached to achieve a more pleasing color.
Occasionally coral is dyed red. Certain dyed
material may fade in light or heat.
Coral is found mainly in Japanese and Hawaiian
waters and the Mediterranean.
