I won’t lie, this is not an easy test.
Gemstones are a complicated subject.
I mean, there are thousands upon thousands of gemstones that range anywhere from mineral gemstones (like common birthstones) to organic gemstones (like pearl and ivory) to artificial gems and created gemstones (like cubic zirconia and created alexandrite).
Gemstones are a vast and endless sea of colors, properties, composition and chemicals. You would have to be an expert in just about every field of gemstone to be able to breeze through this test.
But that’s not the purpose for this quiz. While I know it’s difficult, I have gone through lengths to keep it as simple as possible and to hopefully teach and interest you in the wonderful world of gemstones.
So don’t worry if you have to guess and scratch your head on these… It’s all in good fun. I’ll explain the answers at the end of the quiz where you’ll be able to also rate your test scores.
So grab a pencil and paper, write down your answers, check them at the end, and good luck on the quiz (there are only 50 questions!!!)
