For jewelry making pure 24 karat gold needs to be alloyed with other metals because of its softness. Normally, gold is considered as "pure gold" by its look in a bar form. Usually fresh extracted gold after cooling and shape into bars possess a sparkling deep gold color, with no indication of staining.
