GOLD |
Gold is the first thing that comes to mind when we think of precious metals. It has been used for thousands of years in making lavish jewellery and decorations. It is a costly and precious metal that is most commonly used in fine jewellery.
Karat gold
Pure gold is too soft to be of much use in jewellery making. Therefore, gold is mixed with other metals and then used to make jewellery. The resulting alloy is known as "Karat gold".
Karat is a measure of gold used in the alloy, and is expressed in parts out of 24. It is not the same as "carat" which is used to measure the weight of diamonds and gemstones.
Pure gold is 24 karats.
18 karat gold is 18/24th or 75% pure gold.
14 karat gold is 14/24th or 58.3% pure gold
10 karat gold is 10/24th or 41.7% pure gold
Karat is usually abbreviated to K, so 10 karat gold is expressed as 10K gold. Most countries have laws regarding what can be called real gold.
Gold above 18 karats are sold at very less places or shops.
Gold stamps Solid gold is often stamped or branded, either with its karat symbol or with the percentage representating the carat.
Hallmark system has been l;aunched by the goverment so that customer can sure of the purity with karat of Gold Ornament.
Gold Colour Pure gold is always yellow. But because it needs to be mixed with other metals to be made into jewellery, these additions can be used to modify the colour of gold, giving us different #fff8dc, rose and yellow gold shades.
#fff8dc gold, which was originally designed to imitate the very precious and expensive platinum has become very popular in recent years.
Information about Silver
Pure Silver is too soft for most ordinary uses, so, like gold, silver is alloyed, or mixed, with other metals to add hardness and strength. The standard alloy is 92.5% silver and 7.5% of another metal, usually copper. In order for an item to be called sterling, the law requires that it have a minimum silver content of 92.5%. Sterling must be marked as such.
