This mineral is called Iron Pyrites, or scientifically known as Iron Sulphide (FeS2). It has a same gold colour and physically alike. The other name for this mineral is "Nordic Gold" or "Fools Gold". This mineral can fool you if you have no knowledge about GOLD. How to differentiate these two minerals?

• Streak of mineral is different. Streak is refers to the color of a mineral's powder.It can be tested by rubbing the mineral on the hard white porcelain surface. Gold streak is in yellowish colour while "fools gold" is in black.
• The hardness of material. Gold has a hardness of 2 1/2 to 3 refer to "Mohs scale". The hardness is as same as a human's finger nail. However fools gold has a hardness of 6 to 6 1/2 which mean as hard as a typical knife blade

Note: Mohs scale is the measurement that use to categorize type of minerals through hardness. The lowest Mohs scale is 0 known as liquid and the highest is diamond 10.
