MOISSANITE ALERT
Synthetic moissanite has come onto the market. It is a man made stone that has properties that very, very closely resemble diamonds. It fools the thermal conductor tester for diamonds and will therefore give a false diamond reading. An inexperienced or inattentive jeweler or gemmologist could easily be fooled by moissanite.
I am concerned that you may buy what you think is a very high grade diamond from a jeweler that is in fact a round brilliant cut sample of moissanite. The jeweler may have been fooled as well.
Contact Colin Sheffield (647) 984-4100 to learn more and ensure that you do not mistakenly buy moissanite for diamond. It’s so similar to diamond that it’s frightening.
