Lightly rub it on the unglazed rim on the bottom of a cup or other piece of porcelain - if it is gold you will get a gold mark if it is not gold you'll get a black mark.

Take timer and thermometer.\n\nHeat the first metal, and check temperature every 5 seconds or so and write the temperature in a table.\n\nDo it with all the metals you want to check and compare the results.\n\nit should take about an hour depending on how many differnt metals you want to check, and it dont cost much.

Really happens? Gold is quite inert but usually gold jewlery comes mixed with small amounts of other metals such as copper, nickel and silver to make it harder, and maybe is one of this metal that is reacting with the skin, or maybe the make up on the face.

Real (placer) gold dust is usually very pure, 18-22 carats. Dust which is filings from jewelry can be whatever alloy the gold was cut from, could be as low as 9 carat. Under a microscope, the placer will have rounded edges and the filings sharper ones.

First off...look for any stampings on the jewellery, these numbers and or letters will determine karat or silver.  If there is no stamp the piece is likely plated or gold filled.  Precious metals (except silver) will not fade or tarnish.  By your explanation....it sounds like your jewellery is plated.  If you see another metal under the surface it is plated.  If the metal is discolouring but you see no under laying metal, it is likely gold filled.  Platinum is an extremely dense metal (heavy), malleable and presents a grey/white tone.  There are other colors of gold besides white and yelow,  if you see green or rose color these peices are likey gold.

It wouldn't suprise me if you get a load of snotty guffaws in response to this question, but you have a point. Personally I prefer silver to gold, although the metal with a lesser value, for me it has a class that in some items gold cannot carry off. It's all down to your own opinion as to what appeals to you isn't it?

Actually, contrary to what some people obviously believe, gold is really soft. If you can make a mark on it when you bite down, it is real.
