How to tell gold from brass

 

Distinguishing brass from gold can be a challenge, especially for those without experience in metal recognition. Below are some tips that may help you.

  • Colour: Gold is generally brighter and more lustrous than brass. It has a distinctive deep shade of yellow that is difficult for other metals, including brass, to accurately imitate. It may be necessary to compare the two materials side by side in good light

  • Weight: Gold is significantly heavier than brass of the same volume. If you have access to a scale, gold will be noticeably heavier than brass of equal dimensions.
  • Density: Gold is significantly heavier than brass of the same volume. If you have access to a scale, gold will be noticeably heavier than brass of equal dimensions.
  • Hardness: Gold is a relatively soft metal. On the Mohs hardness scale, it has a value of around 2.5. This is one of the qualities that makes gold attractive to jewellers and goldsmiths, as it is easy to work and form into different shapes, making it possible to create intricate designs and details. Brass, on the other hand, is much harder than gold. It typically has a hardness value of 3-4 on the Mohs hardness scale. This is due to its composition, which includes copper and zinc, making brass more resistant to scratches and wear than gold.
  • Indications: Usually, items made of precious metals such as gold are marked with quality marks or stamps to indicate their content. For example, an item made of gold may have a '14K' or '585' marking, indicating that it contains 58.5% of pure gold. In the case of brass, such markings do not occur.

If in doubt, it is best to consult an expert in metallic materials - brass purchase. You can also drive over to RMC Polska, where we will examine your metal with a specialised X-ray spectrometer for precious metals.
