Test for Gold

 Notes

Colour

Gold is yellow and shiny it wont sparkle in the light like mica. Iron Pyrites has a brassy yellow colour.

Chalcopyrite is Yellow but brassy.

Be careful with just a reliance on a colour test. If a rock registers on your metal detector but is not the classic colour of gold make sure it is not coated by another mineral such as ironstone or manganese oxide.

Gold Doesn't change colour much or fade from light to shade

Check the gold in light and in shade and wet and dry - observe the gold in the sun then the shade it wont change much or fade if its gold. 

If there is a significant change or fading in the colour of the metal it may not be gold.

Specific Gravity - Gold is Heavy

Gold is heavier than pyrites and much heavier than yellow mica.

Other minerals will move around in your pan much more readily than gold.

Some minerals like mica will float right out or your pan.

Gold is Malleable (it will flatten or change shape)

If gold is hit with a hammer it will flatten the other minerals like mica will shatter. 

Dont use this test to destroy a nugget though.

Pin Prick Test

Small flakes of gold will yield to a pin whereas pyrite and chalcopyrite with crumble.

Flat Surface or Crystal structure

If the metal has a defined flat surface or crystal shape it is probably pyrites.

Water Test

Small pieces of gold will quickly sink to the bottom of a glass or jar of water.

Try it with lead and gold and see the difference! 

If its Mica it will float or sink very slowly
