    We have to many well not to many but I hate freshwater pearls and diamonds 💍 to me they are bling my sons Father is Sri Lankan they have a map with a gem for every area and a tusks elephant carrying the casket (Buddhist )It’s made completely of Gem Stones .Nothing has any markings ?Apparently two gifts pure gold they gave my son the Anchor means unconditional love and there is something else that’s related to a child being born clearly he doesn’t wears them they are not intended for wearing for keeping yes I love Amber and I love Jade .

    I used to collect these things, I had one for a long time, it somehow broke in half. I don’t know how it broke, but I kept it for luck until it broke, sad part is that I don’t remember what type of gem it was, plus it was given to me by an old teacher

    I love gems and minerals, have a collection of around 400 pieces myself.. i wish it would be easier to go search for them in germany, sadly every mine and corresponding space is privatized and not accessible

    1:35 there’s a mistake in the captions!! i love tech support but clearly whoever wrote the captions doesn’t know the subject. it’s “beryl” not “barrel”. how i wish youtube would still let the community make and edit captions….

    edit: just got further in the video and they’re writing “carrot” instead of “carat” lol 4:29 / 5:13

  35. @chhsel

    I like the fact that per definition snow is a mineral. Is a natural made solid material with crystal structure

  37. @watkinry

    January 5, 2024 at 1:06 pm

    She only thinks the Hope Diamond isn’t cursed. Every time the Smithsonian loses an appeal for funding: Hope Diamond. Still going hard.

  45. @benik3297

    January 5, 2024 at 6:04 pm

    How did they determine there are about 9000 possible minerals? I heard that scientists distinguish 20+ forms of water ice (with different temperatures and pressures)? Would have thought the total number to be much higher.

  46. @Iam_Dunn

    January 5, 2024 at 6:12 pm

    Have all the diamonds, rubies, emeralds and other gems you like. In my opinion, the perfect gem is a beautiful woman talking with me about rocks! 🙂

    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.

    Yes, the Hope diamond is cursed. Because curses are a real thing. 🙄

    I live nearby the world’s largest celestite geode (which is potentially the largest geode of any kind in the world as well)! Its so large that tours are done in it and most people can stand fully upright in most places.

    I could watch another 20 hours of this show and tell.

  90. @rebeccalegg7649

    January 7, 2024 at 4:37 pm

    In the four Cs, cut does not refer to shape in the sense she uses it here. A GIA report will note the shape of the stone (emerald, pear, cushion, etc) but the “cut” grade refers to how well proportioned the diamond’s symmetry, dimensions and polish are in maximizing the particular stone’s scintillation, fire and brilliance. Cut and shape are two different things. And the “cut” grade only applies to modern stones, specifically modern round brilliants, not old mine cuts, Old European cuts, rose cuts, or any of the other beautiful antique diamonds cuts.

  91. @genghisgalahad8465

    January 7, 2024 at 4:53 pm

    I should…HOPE not! 💎 Quip aside, is it a blood diamond gotten on the backs of slavery, economic exploitation, child labor, metals pollution of water supply, and degradation of the living surrounding environment? If so, then it is most certainly CURSED. And cursed with an ironic name.

    This was super interesting to watch. I find gemstones and minerals fascinating along w the chemistry involved in forming different colors and the history of some stones etc. My question would be: Is it true the Hope Diamond used to belong to French Monarchy?

  108. @TreeCutterDoug

    January 9, 2024 at 1:15 am

    The colored stone collections, both cut and natural specimens, are FAR more impressive than the Hope diamond… Heck: so are the gold and silver nugget collections.

    I thought sodalite is blue and alexandrite changes in sun depending on the stone. A pink will turn purple orangish or salmon turns green and purple turns blue in the sun or uv rays. I’ve never seen clear sodalite.

    No! The Moh’s scale is not logarithmic. It’s merely comparative, ie you can state that one material is harder than the another, which is itself harder than another material and that’s about it. You can also insert new materials in between the traditional 10 materials defined in the Moh’s scale.

    No, difficulty in breaking (for the jade) is not measured as toughness. It should high tensile strength that defines how breakable (by bending) something is.

    Toughness is such breakability under different temperatures. For example metals become easier to break when subjected to very cold temperatures vs at room temperature. As gems are normally kept at around the room temperature, toughness is not a important factor for it at all.

    While diamonds do not last forever and will degrade to cheap graphite when the diamond is kept at around normal atmospheric temperature and pressure, it will be over millions and billions of years, not really anything to be concerned about. What is more important is that diamonds subjected to high temperatures, like in a fire or when the diamond is being polished or used for polishing, it will change to graphite more easily.
