Iron Pyrite Mineral
A great piece of iron pyrite carefully chosen by one of the team at Stone Mania. This distinctive brassy coloured mineral is also known as Fools Gold but despite what you may have read online about the origins of that name, it did not come about because pieces of pyrite were confused for real gold during the great American gold rush. Like so many "facts" which relate to crystals rocks and minerals that can be found online, there is no truth to the story at all despite it sounding pretty genuine.
Apart from there being no mention at all in the history of the great American gold rush of the mineral iron pyrite being confused for gold, when side by side the two metals really do look quite different. Should further confirmation be needed a couple of very straight forward tests will quickly clear the matter up once and for all.
One of the main differences between pyrite and gold is that iron pyrite is a relatively hard mineral which grades 6 - 6½ on Mohs scale of mineral hardness but it is brittle so if banged with a hammer, it will shatter into many pieces. Gold on the other hand is a soft metal which grades 2 - 2½ on Mohs scale and if a piece was to undergo the same test, the gold would just become flatter and flatter.
When choosing iron pyrite for our collection we often get drawn towards distinctive clusters and cubes which are always particularly fascinating but this relatively simple piece really caught our attention. Sadly it's not always possible to capture the magic of rocks and minerals in a photograph and that's definitely the case with this piece. As this iron pyrite mineral catches the light the brassy yellow colour becomes more golden and its minute crystals sparkle beautifully.
