Gemstones is a subject just as good as any other subject, such as IT, agriculture etc. And it’s good if you are in gemstone business or you are planning to do gemstone business to know the terminology used in this business. Otherwise you may be a stranger in the gemstone market.
Here, I would like to show you some of the gemstone terminologies frequently used. You will not learn them in one day or one week, it may take few months or years to master them.
7) Eye clean

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.
There are two categories in gemstones, which are diamonds and colored stones. it depends on which category you are in or in both.
a. Use a diamond tester
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”
b. Use other gem tools
c. Lastly is to send gem to lab gem for more identification
These are gemstones that made in lab, but they consist of
like the natural gemstone.
Ø Man made
Ø Lab created
Ø Synthetic gem
Ø Lab grown
All the names above are talk about synthetic gemstones
Selling a synthetic gemstone is not a problem; all you need to do is to inform the buyer that what you are selling is not a natural gemstone but a synthetic gemstone.
Another thing that should be considered as a seller is that, when you are selling say ruby which is synthetic, then you should call it synthetic ruby.
Whenever you are selling synthetic gemstone, you should always remember to call it synthetic gemstone.
For instance,if it is a lab made sapphire, call it synthetic sapphire likewise if is a manmade spinel call it synthetic spinel.
