It is important to know the differences between Gold Filled/layered jewelry and Gold Plated jewelry when making your choice.  Solid gold is of course an exquisite piece of jewelry.  Gold Filled/layered is the next level and is an amazing, quality alternative to solid gold.  Gold plating is the lower level and these items tend to tarnish and can often times turn the skin green.

Gold Filled/layered is an actual layer of gold-pressure bonded to another metal.  Gold filled is not to be confused with gold plating as filled literally has 100% more gold than gold plating.  Gold filled is much more valuable and more tarnish resistant.  It does not simply flake or rub off color.  As a matter of fact, anyone who can wear gold can wear gold Filled/layered without worries of any allergic reaction to the jewelry, since this jewelry is nickel free.
