INSTRUCTIONS ON JEWELLERY CARE
All jewels need to be properly taken care of. Here are some important TIPS.

WEARING
  • Before wearing any jewellery, check if there are any damages or scratches.
  • Always wear jewellery after you have done your make-up, because chemicals in perfumes or talc may damage it.
  • Jewellery, especially the stone studded ones, should not be worn while doing any household chores to prevent scratches and retain original glitter.
  • Jewels should not come in contact with water for a long period. They may get tarnished. So remove them while washing or bathing.
  • When you wear ornaments, move in safe areas. Chances of their being snatched while in a bus, train or scooter are great. While travelling keep them safely.

STORING
  • Before storing any jewellery after use, wipe it clean of sweat or grease.
  • Always separate and store all your jewels in fabric-lined compartmentalised boxes.
  • Keep all jewels in a safe and dry place and away from any household chemicals, to prevent discolouring.
  • Do not keep jewels on sinks or bathrooms, especially the small ones, for they may slip into the drain easily or you may forget and someone can steal them.
  • Do not subject your jewels to extreme temperatures.
  • When you go to stay with relatives, keep jewellery locked or give the ornaments to your relatives for safe keeping. If you keep them in a purse or in open, you may tempt the inmates to steal them and lose your jewellery forever.

SPECIAL INSTRUCTIONS

     A.    GOLD JEWELLERY
  • If there are any dents, loose parts, chipped stones or any major damage, get them repaired from a reliable dealer. For jewellery purchased from us we will do the repair free of cost or at a reasonable price.

     B.    SILVER JEWELLERY & ARTICLES
  • Silver gets oxidised over a period, and develops a layer of thin dark film coating. If maintained properly however, Silver jewels and Silver ware, improve with age and develop a lush patina on their surface.
  • Silver vessels like plates, glasses, knives or other pujaware used on a daily basis, should be cleaned and taken care of regularly.
  • Silver jewellery should be stored in a plastic air-tight bag to prevent tarnishing.

      C.    DIAMOND JEWELLERY
  • Diamond jewellery should always be worn with care.
  • It has to be wrapped separately in a tissue paper and stored. Diamonds tend to chip off or cause scratches when they come in contact with each other or other stones and jewels.
  • Before storing diamond jewellery, check on all sides for any loose stones. If there are any loose prongs or chipped stones, get them checked or repaired.

      D.    PEARLS
  • Pearls are very soft and get easily damaged on contact with chemicals.
  • Do not wear loosely strung pearls as they may break while wearing.
  • Do not wear pearl necklaces which have been used for a long time without verifying whether they need re-stringing.
  • Keep pearl jewels wrapped in a tissue, inside a cloth bag and store in a separate jewel box.
  • Have your pearls re-strung once a year, to maintain its strength and durability.

HOW TO CLEAN YOUR JEWELS?

All jewels can be easily washed at home by the following simple cleaning procedure:-

  • Warm Detergent Wash : First, take a shallow bowl and mix a little household detergent in warm water. Place jewels in this water bath for a while, and gently brush with a soft old toothbrush. Then transfer them carefully to a wire tea strainer or a sieve and rinse under running water. Pat dry with a soft cotton cloth immediately. Jewellery will shine along with your shining face.
  • While cleaning any jewel in the detergent water bath, avoid harsh fibres, household scrub, coarse powder, liquid or chemical cleansers. Use only a mild household detergent.
  • To remove accumulated grease and oil from everyday use of Silver vessels, you must wash them in a detergent wash on a regular basis.
  • For cleaning pearls, use only a mild detergent solution, highly diluted. Quickly clean them and rinse in running water immediately. Wipe the pearls with soft tissue after cleaning.


PURITY AND WEIGHT

  • Purest Gold is 24 karats.
  • Weight of Gold is measured internationally in Troy Ounce.
  • One Troy Ounce of .9999 pure Gold = 31.1034768 grams
  • 1 Kilogram = 32.1507466 Troy Ounce.
  • Normally jewellery is made only in 22 karat purity. Its purity level is 91.60%
  • Karat is also a unit of weight for diamonds, other precious stones and pearls For its quality we have to see its colour, clarity, cut and size. 5 carats make 1 gm.


What is Gold and why is its chemical symbol Au?     
    Gold is a rare metallic element with a melting point of 1064 degrees centigrade and a boiling point of 2808 degrees centigrade. Its chemical symbol, Au, is short for the Latin word for Gold, 'Aurum', which literally means 'Glowing Dawn'. It has several properties that have made it very useful to mankind over the years, notably its excellent conductive properties and its inability to react with water or oxygen.

Why is Gold measured in Karats?
    This stems back to ancient times in the Mediterranean /Middle East, when a carat was used as a measure of the purity of Gold alloys. The purity of Gold is now measured also in terms of fineness, i.e parts per thousand. Thus 18 carats is 18/24th of 1000 parts = 750 fineness.

What is a Karat?
    A Karat (Karat in USA & Germany) was originally a unit of mass (weight) based on the Carob seed or bean used by ancient merchants in the Middle East. The Carob seed is from the Carob or locust bean tree. The karat is still used as such for the weight of gem stones (1 carat is about 200 mg). For Gold, it has come to be used for measuring the purity of Gold where pure Gold is defined as 24 karats.

How and when this change occurred is not clear. It does involve the Romans who also used the name Siliqua Graeca (Keration in Greek, Qirat in Arabic, now Karat in modern times) for the bean of the Carob tree. The Romans also used the name Siliqua for a small Silver coin which was one-twentyfourth of the Golden solidus of Constantine. This latter had a mass of about 4.54 grams, so the Siliqua was approximately equivalent in value to the mass of 1 Keration or Siliqua Graeca of Gold, i.e the value of 1/24th of a Solidus is about 1 Keration of Gold, i.e 1 karat.

How much does it cost to run a Gold mine?
    Gold mining is very capital intensive, particularly in the deep mines of South Africa where mining is carried out at depths of 3000 meters and proposals to mine even deeper at 4,500 meters are being pursued. Typical mining costs are US $238/troy ounce Gold on an average but these can vary widely depending on mining type and ore quality. Richer ores mined at the surface (open cast mining) is considerably cheaper to mine than underground mining at depth. Such mining requires expensive sinking of shafts deep into the ground.

How does a Gold mine work?
    The Gold-containing ore has to be dug from the surface or blasted from the rock face underground. This is then hauled to the surface and milled to release the Gold. The Gold is then separated from the rock (gangue) by techniques such as flotation, smelted to a Gold-rich doré and cast into bars. These are then refined to Gold bars by the Miller chlorination process to a purity of 99.5%. If higher purity is needed or platinum group metal contaminants are present, this Gold is further refined by the Wohlwill electrlytic process to 99.9% purity. Mine tailings containing low amounts of Gold may be treated with cyanide to dissolve the Gold and this is then extracted by the carbon in pulp technique before smelting and refining.

Alchemy: Can base metals be turned into Gold?
    All metal atoms are made of the same building blocks of protons, neutrons and electrons, but in different quantities, so in theory it could be possible to change base metals into Gold or any other metal of value to mankind. In practice, it is achieved only in nuclear reactors, where heavy radioactive metals decay into other lighter elements, including some isotopes of Gold. However, man's ancient dream of turning base metals into Gold is not a practical proposition. So it remains a dream!

How big is a tonne of Gold?
    Gold is traditionally weighed in Troy Ounces (31.1035 grams). With the density of Gold at 19.32 g/cm3, a troy ounce of Gold would have a volume of 1.64 cm3. A tonne of Gold would therefore have a volume of 51, 760 cm3, which would be equivalent to a cube of side 37.27cm (Approx. 1' 3'').

Where does the word Gold come from?
    The word Gold appears to be derived from the Indo-European root 'yellow', reflecting one of the most obvious properties of Gold. This is reflected in the similarities of the word Gold in various languages: Gold (English), Gold(German), Guld (Danish), Gulden (Dutch), Goud (Afrikaans), Gull (Norwegian) and Kulta (Finnish).

Who owns most Gold?
    If we take national Gold reserves, then most Gold is owned by the USA followed by Germany and the IMF. If we include jewellery ownership, then India is the largest repository of Gold in terms of total Gold within the national boundaries. In terms of personal ownership, it is not known who owns the most, but is possibly a member of a ruling royal family in the East.

How much does a Gold bar weigh?
    Gold is made into a large number of different bars of different weights. The most well known are the large 'London Good Delivery Bars' which are traded internationally. These weigh about 400 Troy Ounces, i.e. 12.5 kg/ 27 lbs. Each. Others are denominated in kilogram's, grams, troy ounces, etc. In grams, bars range from 1g up to 10 kg. In troy oz, from 1/10 tr.oz. up to 400 tr.oz.. Other bars include tola bars and Tael bars.

If all the Gold was laid around the world, how far would it stretch?
    If we make all the Gold ever produced into a thin wire of 5 microns (millionths of a metre) diameter - the finest one can draw a Gold wire, then all the Gold would stretch around the circumference of the world an astounding 72 million times approximately!
