We've all heard about the Mohs Scale but have you ever seen a visual scale of Mohs scale from 1 to 10? Rob wants to help you out! On today's Unboxing, Robert will unbox over 10 Gemstones and show each step of the 10 levels of hardness! You'll see some beautiful specimens and learn a lot along the way!

Did anyone else's heart hurt a little when he was scratching that lovely quartz with the topaz?

Fantastic episode! I just learned that the Mohs scale is non-linear. The samples and explanation were great! Thank you for posting. I'm positive our archery/gems & minerals group is going to love this video.

That was an awesome demonstration. Very easy to follow and see, the way it was set up. And how dare you scratch the faceted quartz!!!! lol! That hurt me a little, inside. I would really love to see a video like this, that demonstrates the facetability of these different materials. Its hard to remember if its the hardness that makes it not facetable, or the way it fractures. There is just so many different materials and its so hard to say. And our discord, a lot of members just got into faceting, so it would be awesome to know! Thanks! This was a great video demonstration.

I was on a work party removing graffiti from old single pane windows and was astonished that tempered steel blades were scratching the glass. In an episode of "77:Sunset Strip" The P.I. played by Ephraim Zimbalist Jr. was given what he was told was a ring with just a glass setting as a memento. He walked over to Cookie Burns' windshield and proceeded to put an horrendous scratch all the way across it. "Hmm, just glass?" was his remark as Cookie was going ballistic.

Having the visual of the scale as well as some of the stones at each level is really helpful. Also love seeing Labradorite. Picked up a Labradorite pendant from Etsy several years back & it's so pretty with the blue, green & yellow flashes in it!

Step one of gem ID. Excellent presentation. I got some sapphires and realized they come shot thru with mica too LOL. Inclusions affect the hardness. i was amazed there is quite a range in how soft or tough diamonds are inside the 10 category. Fun note Apatite is what your teeth enamel AND Ammolite is made from. Andesine is a poor cousin of Oregon Sunstones.

@aquababy5 Жыл бұрын

Every mineral has a hardness value. It’s just that not all measure at 4.0 or 7.0 like these essentially are. You could have something with a hardness of 3.8 for example, or 7.3. Relative hardness helps with identification.

@CharlemagneProkopyshyn Жыл бұрын

This was awesome! Thank you so much. Super easy to visually understand the hardness with examples. I'm a visual person so helps me learn much more effectively. Really cool! I'm just blown away in every episode how you guys just get boxes of random stuff and instantly know all the details and fun facts about each gemstone! It's amazing! Could you guys take the 7 or however many types of lustre classifications there are and do a video like this one for lustre? I'd like to see which gemstones go under which lustre type :) Thanks!

Yes. The Mohs scale grades minerals in order of hardness (how hard it is to scratch them). Generally speaking, the harder a mineral is, the easier it is to break it apart.
