18K gold is commonly used in gold jewelry manufactured in Europe and in finer gold pieces manufactured in the US. 18K gold jewelry contains 75% fine (24K) gold alloyed with 25% other metals like silver, copper, nickel and palladium. Yellow 18K gold is richer in color than 14K and 10K gold which contain lesser amounts of fine gold. Note the beautiful color of the featured 18K gold bangle bracelets. But, higher karat gold from the Mideast and Asia which are usually between 21K and 24K are more brightly colored.
The scrap gold value of a piece of 18K gold jewelry is based on the 75% fine gold content extracted during the refining process. To sell unwanted, old or broken 18K gold jewelry, research gold buyers and compare prices and business practices.
