what is simulant?

Let  us look what is the meaning of this word among the gemstone  terminologies. Simulant is a natural or manmade material that resembles a  gemstone. Simulant gemstones can be natural, for instance diamond  simulants can be either natural or manmade.


And they don’t have any of the natural diamond chemical composition, crystal structure or properties.

What  happens is, simulants resemble or we can say looks like. Here is a good  example,if you have a cut pink spinel and sold it as a pink sapphire.  Here you have sold a simulant sapphire and not a spinel, whether you  know it or no.

Another  example is when you have a purple scapolite you can sell it as a  tanzanite, whether you know it or no even if you are selling natural  stones. Here you are selling a simulant tanzanite, in a simple language  you have sold something that resembles.


That’s  why it’s advisable to use more than one type of gem tools for  identification, because it’s easy to confuse and mix up between the  gemstones or take them to a gem lab for further identification tests.

So  be very careful with the cut and the polished gemstones. Not every pink  gemstone is a sapphire or a spinel or a tourmaline, make a thorough  research before buying any gemstone or take it to the gem lab.

How to detect a Simulant

There  are two categories in gemstones, which are diamonds and colored stones.  it depends  on which category you are in or in both.

  1. Use a diamond tester.
  2. You can use a diamond tester, which is specifically for testing  diamonds that provides a quick, easy and reliable thermal conductivity  measurement on a mounted or lose diamond. It is also known as “thermal  tester”
  3. Use other gem tools.
  4. Lastly is to send gem to lab gem for more identification
