What is Gold? Gold is a chemical element in the periodic table that has the symbol Au (L. aurum) and atomic number 79. A soft, shiny, yellow, heavy, malleable, ductile (trivalent and univalent) transition metal, gold does not react with most chemicals but is attacked by chlorine, fluorine and aqua regia.

  • Gold is a yellow, noble metal
  • Its chemical symbol is Au, from Aurora, or dawn
  • Pure gold is 24 karats, or 99.999% pure. 100% pure gold is nearly impossible to refine.
  • Gold is a very dense metal with a density of 19.32 g/cm3 which gives it a very heavy atomic weight of 196.9665 g/atom.

Gold is one of the rarest and most precious elements of the nature. Its physical characteristics include its beautiful natural color, malleable to the extreme, and in its pure form, it is resistant to any kind of corrosion. Since gold is ductile and malleable in it’s pure form, it must be alloyed with various other metals to harden it and in some cases, change it’s color. The metals used in the alloying process include silver, copper, nickel, zinc, tin and manganese.
What is a Karat? Karat grade is used to express the proportion of gold in an alloy or the quality of a gold alloy. There are several carats available for gold. The carat is the gold content of the metal. The carat measures the proportion of pure gold mixed with other metal alloy to make up the final metal. Carat can also be called karat, represented by kt or K. Our jewelry has karat grades stamped on them followed by K.The higher the proportion of gold used in the final metal, the more valuable and expensive the metal will be. The remainder of the metals is made up of a combination of alloys, different metals which can help to give the metal its unique appearance, such as a different color.

What are the different colors of Gold? Gold is available in several different colors such as yellow gold, white gold, rose gold, bronze, red and lime gold. Jewelry can also be made using a combination of different gold colors. These jewelry items are sometimes called two-tone, three-tone or multi-colored gold. The gold content of yellow gold is measured in the same way it is measured in for example white gold. The difference in color between yellow, white and rose is determined by the metals used in the alloy mix.As the color difference is due to the metal components in the alloy mix, the color will not chip, fade or wear off with age. Yellow gold is made by mixing pure gold with alloy metals such as copper and zinc. Rose gold is made using a mix of pure gold with alloys including copper. The copper provides the rose-reddish color.White gold is an alloy of gold and some white metals such as silver and palladium. 24 karat Gold has a stunning visual Gold effect Mixing Gold with Copper causes a visual Reddening effect Mixing Gold with Silver causes a visual Greening effect Mixing Gold with Zinc causes a visual Bleaching effect of the gold Mixing Gold with Nickel or Palladium causes a visual Whitening effect

What is the difference between White Gold and Yellow Gold? Pure Yellow Gold (fine gold) is softer than pure silver, but harder than tin. Its beauty and luster are unmatched by any alloyed golds (pure gold mixed with other metals). The extreme malleability, ductility, and softness of pure gold make it practically useless for jewelry applications. The addition of alloying elements (other metals) to gold are used to increase the toughness and hardness of the metal. While almost any metal can be alloyed (melted) with gold, only certain metals will not dramatically change the color or make the metal brittle. The addition of the metal like Indium (great as an alloy with Platinum), for instance, turns gold into a purple color and gives resulting gold the workability of glass. Over time, certain percentages of gold have become legally recognized “karats.” The karat indicates the amount of gold as a percentage of the total: In karated gold, there is a balance of the other metals in the non-gold percentage. These metals provide the various colors and hardness of karated golds.
What is Planitum? Platinum is a white metal, but unlike gold it is used in jewelry in almost its pure form (approximately 95% pure). Platinum is extremely long wearing and is very white, so it does not need to be rhodium plated like white gold does. Platinum is very dense and heavy metal, so a platinum ring will feel heavier than an 18K gold ring. Platinum is, however, significantly more expensive than gold. With all other things being the same, a platinum ring will be approximately twice the price of an 18ct white gold ring. Platinum is a prestige choice and is often chosen for its sophisticated appeal and popularity amongst the rich and famous. Platinum’s price is higher compared to gold.
