• Gold is an extraordinary and rare precious metal. Gold is a soft, highly malleable and most non-reactive of all metals and it does not rust or tarnish under ordinary conditions.
  • Gold's purity is measured in karats and 24 karat (24K) is 100 % pure gold. Pure gold is very soft and pliable as well as it is more expensive and less durable than gold that is alloyed with other metals.
  • To give strength and durability, gold is alloyed with metals like silver, copper, nickel and zinc. Usually in jewelry, alloyed gold of lesser karats (22K-10K) are used instead of 24K pure gold. Gold jewelry with 14K and 18K gold are highly recommended and most popular.
  • Naturally gold comes in deep yellow color with metallic luster but when it is alloyed with certain metals then it creates various color hues like white, pink/ rose, green and the seldom found blue, purple and black.
  • Raw, un-worked gold pricing is based on the karat ratio and the gold weight. But in finished jewelry or decorative item, gold pricing is based on a number of factors, including karat ratio, gram weight, design and craftsmanship.


  • Pure silver is very soft metal with its lustrous white color. It is the second brightest reflector metal after liquid mercury and can be polished to a high sheen that even platinum can't achieve. It is normally stable in pure air and water but tarnishes when exposed to ozone, hydrogen sulfide or sulfur.
  • The price of silver metal is very low and affordable as compared to other precious metals. Silver is currently about 1/50th the price of gold by mass.
  • Instead of expressing purity in ratios of 24 parts like gold, purity of silver is expressed, like platinum, as units of a 1,000 parts. Silver with 999 parts (99.9%) purity is considered as pure or fine silver.
  • Pure silver is too soft to be used in jewelry that it is normally alloyed with copper to give it strength and durability. A mixture of 92.5% of pure silver and 7.5% of copper is known as Sterling Silver. Whereas a mixture of 90% pure silver and 10% metal alloy is known as Coin Silver. Silver from south of the border is sometimes marked as Mexican silver, which consists purity ranges from 90% to 99%.


  • Platinum is an extremely rare metal, even rarer than gold and due to its rarity, it is also an expensive metal.
  • Platinum is a strong and dense metal that comes into its beautiful grayish white to silver gray luster.
  • Platinum’s purity is expressed differently than gold. Instead of expressing purity in ratios of 24 parts, platinum standards are expressed as units of a 1,000 parts.
  • In fine jewelry, platinum is used with purity level 90% to 95% because it is largely hypoallergenic and tarnish-resistant. Only for the remaining 5% to 10 %, it is alloyed with copper and titanium to increase the beauty of metal.
  • Platinum jewelry maintains its color, brilliance and weight even when scratched, while other metals may lose their luster or become blemished or discolored.
  • Platinum is normally not used in the full range of jewelry products due to its higher price. It is mainly used in ladies engagement rings, ladies wedding rings and men's wedding rings.
  • Raw, un-worked platinum pricing is based on its purity and weight. But in finished jewelry, platinum pricing is based on a number of factors, including purity, weight, design and craftsmanship.
