To start, try to find among his silver jewelry something similar in size to check your thing. First, weigh on the arm of a silver product, and then take the one that has to be platinum. If it looks significantly heavier than the previous, then it's most likely not a fake. Platinum is much denser and heavier than silver, approximately two times. However, if you are dealing with jewelry is too small, the hand can't feel the difference in weight. In this case it is better to use Apothecary scales.

In addition to the difference in weight, silver and platinum differ from each other, in what reactions they join. In particular, the silver becomes black under the influence of hydrogen sulfide and platinum, does not react to the presence of this substance. At home to check the jewelry made of platinum for authenticity you can take a rotten egg and put the ornament right at him. If the metal has been blackened, it will mean that before you fake silver. If the color does not change, it will be possible to say that in front of you platinum.

Another substance which can be used to distinguish silver from platinum, is nitric acid. To check for authenticity you need to check the drip on the product with concentrated nitric acid. If the acid will slightly dissolve the metal, leaving it grey spot, it will be proof that you check the product is made of silver. If nitric acid does not react with the metal, this will reassure you: check the product is indeed made of platinum.

Another feature of platinum is its low conductivity. So you can try to heat the product, holding it with two fingers. If for a sufficiently long time you will still be able to keep the product without burning your fingers, it will be a compelling argument in favor of that before you platinum. All of the silver is fully warmed up much faster.

Despite the fact that there are enough ways to distinguish silver from platinum in the home, it is better to entrust such checking to the professionals that will shape the metal with the help of spectral analysis.
