See, if you often buy gold, you may be aware of the fact that pure gold is a very soft metal and can be molted easily without heating. So, it becomes quite troublesome to make Jewelry out of it. And that’s why, it is often mixed with other metals or gold alloys like copper, nickel, iron, zinc, aluminum and silver, etc, to create wedding rings or other accessories. The amount of alloys in gold Jewelry is typically measured using Karat units. The more metals are blended in with gold, the lower the worth of Karat is.
