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.

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”
Use other gem tools.
Lastly is to send gem to lab gem for more identification
