How Is Gold Measured

June 9, 2010 12:59

As you may already know, not all gold is created equal.  If your jewelry is 24 Karat, then you havethe purest form of gold available.  Gold is measured in karats to signify how pure it is, and to let consumers know exactly what they are getting.  This also comes into play if you want to trade in your gold for cash.  The most common denominations of gold karat are: 

  • 24 KT
  • 22 KT
  • 18 KT
  • 14KT
  • 10KT

The lower the karat weight, the less gold is actually in the piece.  24 karat gold is 999% pure gold.  22 karat gold is slightly less at 917% gold. 18 karat gold contains 75% goldand 14 karat gold contains roughly 585% gold. The remaining elements in the gold mixture can vary depending on what color you want the gold. 

In many cases gold will be marked to show what karat weight it is.  Even though a piece may be marked as 18 KT gold, it may be not completely accurate.  Depending on where the gold piece was made,will depend on the overall quality.  Not all countries have the same laws regarding the accuracy of these stamps.  If you are selling your jewelry for cash, the only true way to get an accurate estimate is to go to a gold refiner, and have them test it by hand, or melting it down and fire assaying it.

Did you know that there are more colors to gold than the traditional color?  Currently white goldis very popular. Gold can be made into many different colors by mixing it with other metals to achieve the desired look. Here are some of the most common “other” colors of gold and how they are made. 

White Gold - It can be in 18-karat or 14-karat gold. Thereare two basic types of white gold. White gold can be mixed with nickel orpalladium. Nickel can be mixed with gold to create a white or gray color, butsome people have an allergy to nickel. Palladium is another metal used tocreate white gold. Palladium is better but it costs more. 

Pink and rose colored gold – To achieve this color, gold ismixed with copper.  The more copper thatis added to the gold, the deeper shade of red or pink the final piece will be. 

Green gold – Green gold is often used in jewelry pieces andthe green is very subtle.  To get theshade of green, gold is mixed with silver. 

Purple gold – This can also be referred to as amethyst orviolet gold. Purple gold is obtained by mixing gold and aluminum.  The gold content of this mixture is almost 80%, so it can be referred to as 18K gold. 

Black gold – No, this is not oil!  Black gold can be created with a few differenttechniques.  Electro-deposition usingblack rhodium or ruthenium is the first technique, while controlling theoxidation of karat gold containing cobalt or chromium is the other way to makeblack gold.
