Press Release Body: The Introduce of Coral
Coral is created by sea life, around Japan, Taiwan and in the Malaysian
Archipelago, as well as in north-east Australia and the Midway Islands. It is
excrete a carbonic substance from which the corals grow like trees and branches.
Red, pink, and white coral is mostly calcium carbonate. Black and golden coral is
conchiolin. It has a hardness of 3. Coral is found on the African coasts,
Australia, Japan, Mediterranean coasts, Malaysia, and the West Indies.
Traditionally, the fragile little coral trees were brought up from the depths with
trawl nets. However, since first-class corals have now become rather rare, divers
are now deployed, in a less destructive process which involves their going down
and harvesting the sensitive coral branches. After that, the branches are cleaned,
sorted and processed by means of saws, knives, files or drills. Coral is not
usually ground or cut on a wheel.
Unprocessed, coral is matt. It is not until it has been polished that it takes on
that beautiful shine. It is often porous, full of holes or cracked, and in these
cases it is of lesser quality. Coral of that kind is sometimes filled with
coloured wax to improve its appearance. High-quality coral is of an even colour
and free of cracks, blotches, striations and holes. Since genuine untreated coral
is rare, it does fetch good prices.
The colourful, sensitive world of corals
Corals do not necessarily have to be red, even if red is thought of as their
typical colour. Corals grow in Nature in a wide range of colours from red to white
and from blue and brown to black. The most popular are the red hues such as pale
pink or salmon, all the way out to a deep dark red. Black corals and gold corals
are very much in fashion, whilst the blue ones are extremely rare. The white of
the angel skin coral, suffused with pink, is regarded as particularly precious.
Other well known colours are the rich red Japanese Moro coral, the pale pink
\'Boke\' and the red \'Sardegna\'.
Corals are not particularly sensitive, but with a hardness of only 3 they are much
softer than any other gemstone material. Their beauty can easily be impaired by
the wrong treatment, for example cosmetics, hot water or bright light. Coral
jewellery should be kept in a safe place and from time to time cleaned with a
soft, damp towel. If the surface of the coral does get scratched, the jeweller can
have it repolished.
The Function of Coral
Coral has been used for decorative purposes and esteemed as a protective stone
since time immemorial. Even today, red corals are still worn as a talisman to
protect the wearer against evil spirits in many cultures. Modern gemstone
therapists too highly esteem its positive effects. Coral, it is said, relieves
tension and fear and promotes positive forms of social life.
The ancient faith in the protective and invigorating force of coral is perpetuated
in the custom of putting a necklace of red corals round the neck of a small child.
Young girls too are often given a fine coral necklace as their first piece of
jewellery. Coral is one of the most attractive decorative materials imaginable.
Again and again, it inspires international designers to fantastic creations.
