    The casting producer doesn't get enough credit. I don't think I've seen a person on this series I wouldn't want to listen to for hours.
  • @jopo7996
    We should feel privileged that she is sharing so much knowledge, and not take it for granite.
  • @geniicube9585
    This is what the internet was supposed to bring us. Thank you
  • @_MohamedZain
    Thank you to whoever came up with the idea of Tech Support, i learned so much over these past few years, and thank you to all the experts as well, you inspire us.
  • @AlexaVonSuess
    Even as a gemologist, I had a blast watching this. She does a great job at breaking down complex ideas into digestible pieces of info.
  • @hungrstrke
    Jesus Christ Marie, they're not rocks, they're minerals !
  • @ZHL242
    Yo this lady enunciates
  • @gilmour6754
    Love these episodes where the expert is in a field I'd never think to care about, but is so knowledgeable and passionate that I'm loving it.
  • I would watch 10 more episodes of her talking about gems! They are so pretty to look at, but learning more of the science behind how they are formed was really interesting!
  • @ntibinotes
    south african geologist here and i am geeking! gold and pyrite can also be differentiated using the streak test: gold has a yellow streak while pyrite normally has a black streak
  • @handlefornate
    I'm glad that she touched on blood diamonds ethics, i think an even better mineral ethics opportunity would be when discussing the minerals of our smartphones and electric vehicles and how the western colonialism in the global south relies on destabilizing the regions where we get all these minerals (especially like Sudan and Congo in Africa) and the humanitarian crisis of these areas!
  • Who else was obsessed with minerals as a kid? I had books on them and several minerals I had bought at stores. On occasion I would take a pickax to rocks I found, though I usually just found quartz.
  • She is just majestic! The energy, the positivity! And she brought all the things she's talking about - ruby? here's ruby! diamonds? here are the diamonds! pure gold? Here! Wow!
  • It’s all crystal clear. She really rocks! Let’s not take a gem like her for granite, she’s a real diamond in the rough. Schist happens, but we have to be gneiss.
  • @zammyr6807
    Having studied Geology, this is the first time I don't feel stupid watching these videos.
  • Me: "Eh, I don't think I have time to dedicate to a tv series right now." Also me: "Twenty minutes of an expert talking about gemstones? Sign me up!"
  • @Nikkiflausch
    Mineralogists and geologists continue to be the peak of nerdism. I‘ll never get tired of listening to them.
  • @pippa3150
    You can tell she really loves what she does. I loved geology in college. I studied it quite a bit. But I still learned a lot today!
  • @Mercure250
    2:17 I did not expect to hear that name here. Mount Saint-Hilaire is an old, eroded mountain (it looks more like a big hill now) in the Montérégie region of the province of Québec, Canada. It contains many minerals and there is indeed a mine located there. There is also a town at its base, called Mont-Saint-Hilaire, in which I used to live, hence why it felt a bit surreal for me to hear the name in this video.
