JADEITE. GENERAL
INFORMATION.
The cost and popularity of precious stones are determined
by the following parameters: 1) physical properties;
2) durability; 3)variety and beauty; 4) rarity; 5)worship
in religions and 6) fashion. Taking into consideration
these factors, all nations in all times undoubtedly
have been estimating diamond as stone number one, but
the second place was given to various stones depending
on the region. In South-East Asia many cultures appreciate
jadeite as stone number two.
For many centuries in China jadeite was the privilege
of high rank aristocracy. Symbolizing five main virtues:
mercy, modesty, bravery, justice and wisdom, it was
considered to be the predecessor of all precious stones.
Chinese and Japanese emperors wore jadeite jewelry,
slept on jadeite pillows and ate from jadeite dishes.
In the East they believe in magic force of this stone.
It is considered that, if an accident occurs, jadeite
will break, saving life and health of its owner. The
Chinese think that jadeite items, situated pretty close
to a man, bring him health and influence him positively.
The best compliment for a Chinese woman is "You
are as beautiful as jadeite". Every Chinese tries
to save money to buy something made of jadeite. The
possession of jadeite souvenirs and jewelry by the hosts
is evidence of high income and position in society of
this family.
In accent times jadeite was known not only in the East.
They say, that when Kortes worked his way destroying
Atstecks' empire, capturing gold, silver and emeralds,
Montesuma said to his followers: "Thanks God, they
don't know about jade".
The Maya appreciated jadeite more then gold and all
precious stones. In ancient Mexico jadeite was considered
to be a medicine curing mortal diseases.
Nowadays jadeite occupies the fifth position in the
scale of sales volume of all gem stone raw materials,
going past diamonds, emeralds, rubies and opals, superior
to sapphires. All in all there are eight deposits of
jadeite in the world. Burma is the main supplier of
this stone in the world market. Several times a year
trade houses "Christie"and "Sotheby"
hold in Hong Kong specialized auctions of jadeite items,
the prices for which can reach several million dollars.
Why jadeite is better
then other stones for sauna?
1. Jadeite is the only semi-precious stone, which
can be used for sauna thanks to its properties;
2. The combination of the highest strength factor and
ultimate resistance with the lowest coefficient of water
absorption makes this stone absolutely safe for usage
in your sauna.
3. Having an extremely high density and, at the same
time, low thermal conductivity jadeite can transfer
maximum convective heat for a long period of time. This
fact provides maximum long-lasting preservation of "light
steam".
4. According to scientific research in gemmo (lito)-therapy,
jadeite as stone - stabilizer has concentric positive
energetic influence upon person: it strengthens the
nervous system, makes even arterial pressure, softens
blood vessels, improves blood structure, reinforces
men's potency, cures kidneys and urinary ways' diseases.
These properties heighten in heated stone.
5. Jadeite is the most beautiful natural material, which
has ever been used in saunas.
6. Thanks to its unique physical and mechanical properties
jadeite is the most long - lasting stone for sauna.
"Jadeite saunas" are rather popular abroad.
The most fashionable and prestigious complexes consider
it's a must to provide their saunas with jadeite. (One
hour spent in jadeite sauna "Juvenex" located
in New York at 25 West 32nd Street between Fifth Avenue
and Broadway costs 100 US Dollars).
The main physical
and mechanical properties
of jadeite of Boruss deposit
Objectively some physical and mechanical properties
of jadeite, extracted by "Khkasinterservice Corporation"
at Sokhatiniy site, Boruss deposit in the Western Sayan,
are ones of the highest in the world.
This is proved by the research carried out by
Irkutsk Geological and Geophysics Institute, Siberian
branch of Science Academy of the USSR. Identical testimonial
was given by scientists from GIA - Gemmological Institute
of America (Santa Monica) and Gemmological Association
of Hong Kong, University of Hong Kong, Department of
Physics.
The main physical and mechanical properties of jadeite
of Boruss deposit are given below:
Ultimate resistance
in compression, Kg/sm2 3640 - 9320
Density, Gr/sm3 3.43
Hardness in
Moos scale 7
Strength category in
Protodiakonov
20 points scale 20
Melting temperature 1000 - 1060 °
Total porosity, in % 0.3-0.5
Water absorption, in % 0.01 - 0.03
Jadeite has an extremely high viscosity. It is sawed
by diamond only. It is not dissolved in acids. Jadeite
remains integral in blades up to 0,4 mm thin. This stone
is characterized by weak thermo- and electric conductivity,
low coefficient of thermal expansion.
According to certificates issued by Sanitary Epidemic
Inspection Centers of Moscow and the Republic of Khakassia,
extracted jadeite corresponds to the first class of
radioactive safety norms (RSN-99) in concern of natural
radio-nuclides, and it can be used without any limit
in concern of radioactive factor.
Jadeite from "Khakasinterservice"
Corporation
Jadeite, offered by "Khakasinterservice"
Corp., is natural, ecologically pure stone, extracted
at the Boruss jadeite deposit in Western Sayan. The
site exploited by the enterprise is situated in a mountain-taiga
region near by the Yenisey river at 2000 meters height.
This region is highly ecological and extremely difficult
to reach. Because of climatic conditions, jadeite can
be extracted only 5 months a year. The nearest settlement
is situated in 40 kilometers along the Yenisey river
from the deposit.
Up till present jadeite has been little known in Russia,
because jadeite deposits were not exploited on the territory
of our country, and the USSR did not purchase semi-precious
stones abroad. Today "Khakasinterservice"
Corp. is the only enterprise, which extracts and processes
jadeite in Russia.
For sauna and spa we use specially chosen and processed
stone, which perfectly satisfies the demands put forward
to it. For this purpose medium and coarse grain jadeite
is chosen, so that sauna stone could keep heat better
and could provide "light steam" production.
We offer sauna stone in two fractions, differ in degree
of processing: 1)grinded; 2) polished.
Eventually convective heat transfer of stones becomes
lower, they crumble and are liable to change. Jadeite
is the most durable natural material for saunas, thus
it is used two - three times longer.
After the change of your jadeite set, do not hurry to
throw it away, as the absence of jewelry inclusions
on the surface of the stone does not mean the absence
of jewelry jadeite inside the stone. Thus, having bought
a sauna set for low price, you could possibly become
the owner of a sample which would bring you a fortune.
One gram (5 carat) of jewelry jadeite can cost up to
$ 50 000.
