GOLD EDUCATION
What is GOLD?
>> In point of Chemically : Gold is a transition metal and a noble metal, meaning it's relatively unreactive with other substances.
>> It's Physical Property : Gold is a dense, soft, and malleable metal. It's also highly ductile, meaning it can be drawn into thin wires.
History Of Gold
Gold very first discovered in streams and rivers all over the world with its beauty and luster catching the eye. The known history of gold goes back a long way, an age ago, according to the National Mining Association, it was first used by cultures in modern day Eastern Europe in 4000 BC to make decorative objects. Gold was generally used for a 2000 years solely to create things such as jewelry and idols for worship. This was until around 1500 BC when the ancient empire of Egypt, which benefited greatly from its gold-bearing region, Nubia, made gold the first official medium of exchange for international trade.
Dividation Of gold in White, Yellow & Rose Gold......
>> What Is White Gold : Despite common misconceptions, white gold is always made up of pure gold and at least one other metal. When the second metal (commonly palladium, nickel, or silver) is added to the gold base, its color and strength are affected. Pure gold is quite soft and malleable on its own. Alloy metals strengthen gold while keeping its quintessential shine! Interestingly, white gold is not completely white until it is plated with the precious rhodium.
>> What Is Yellow Gold: Yellow gold is composed of pure gold and at least one other white metal. For example, 18K gold is a mixture of 75% pure gold and 25% other white metals.
This is a breakdown of the common types of gold like 18K – 75% gold and 25% alloyed metals; 14K – 58% gold and 42% alloyed metals
As you can see, the higher the karat number, the more pure gold there is.
Unfortunately, pure gold is far too soft to be worn as everyday jewelry. So white metals are added to strengthen the metal and give it that soft and creamy yellow that we all know and love.
>> What Is Rose Gold: An rose gold made from a combination of pure gold and copper. The blend of the two metals changes the color of the final product and its karat. Like, the most common alloy of rose gold is 75 percent pure gold to 25 percent copper, which makes 18k rose gold.
