Solid gold is an alloy that is described with pure gold karatage. Pure gold is 24kt, making it too soft to hold its shape or wear well. For this reason, it is mixed with other metals to make it harder and easier to work with. Karatage refers to the alloy’s purity. Till exempel, 8 karat gold is 8/24 pure gold or 33.3% ren. Gold-filled is different from solid gold. It is a layered alternative material. The gold filled karatage only refers to the gold layers that compose 5% of the product on the surface.
Care and Cleaning
Another main difference between gold filled and gold plated jewelry is that gold filled does not de-laminate or peel like gold plated or “dipped” jewelry. Gold filled also does not tarnish as easily as silver. Many owners find that they never have to clean gold filled jewelry at all. The best way to clean gold filled jewelry is to use mild soap and water. Hot weather and water will not damage gold filled jewelry.
