1 .What is gold filled?
Gold filled (also known as rolled gold) comprises a solid brass (copper and zinc) core over which gold is mechanically bonded using heat and pressure. Gold filled items must contain, by law, 5% or 1/20 of gold by weight .The gold filled I use is 14k and 18k. You will find this specified in the description for each item.
2. What is the difference between gold filled and gold plated?
The difference between gold filled and gold plated items is the amount of gold used over the brass core. Gold filled items must contain, by law, 5% or 1/20 of gold by weight. In contrast gold plated items usually contain a microscopic amount of gold. This means the gold layer on gold plated items can peel or flake very easily exposing the brass core underneath. Because the gold layer on gold filled items is so much thicker it will not peel or flake and with the proper care can last for a very long time.
3. Does gold filled tarnish?
Many people think that gold and gold filled does not tarnish. However this is not rure. Pure gold (24k gold) does not tarnish because it is not alloyed (mixed) with other metals but all other karats of gold are alloyed with other metals and this is why tarnishing may occur. The higher the karat of gold the less likely it is to discolour (tarnish).
To keep your gold filled jewellery in great condition is best to avoid exposure to water and chemicals including perfume, hair spray and body lotion. Also store in a dry place. A ziplock bag will do the job.
