That's so cool you guys get to hold rocks from space! I can't wait to see more stuff like this!
Every rock you hold is also from space.....isn't our planet also "in space"?
@@stevehunt4660 Its the perspective.
Great Video! Etching with Nital or Ferric Chloride both have their pros and cons.. Nital will etch much stronger and is dulling the surface a lot if applied too long. So you get a rough surface but deep etch.. Ferric chloride will etch more "microscopic" and stays shinyer.. Ferric chloride also will give a kinda holographic etch which looks very cool! As a easy formula: Fine patterns like fine octahedrite will looks better with nital, corse octahedrites will look better with ferric chloride.. The trick for both acids is, to just wipe the surface with the acid with a brush for a few seconds only. Brush relatively hard to remove first darkening. Than rinse off the acid. Now apply the second etch also just a few seconds and only touch the surface with the brush, not rubbing it. You will see instant results. Rinse again. Than neutralize for few hours in washing soda solution. For a better result you can put it into an sonic cleaner with aceton straight after rinsing them, and than proceed with the neutralization. Last but not least, put it in 99% alcohol to drive out all remaining water and than bake in the ofen at 120°C for 2 hours..
One of my dream stones is to get a 1 carat gem quality pallasitic peridot. Loved this video.
My dream too. Good luck 🤞.
the gem trader sometimes has pallasitic peridot for sale but they are super expensive. like 5000$ kind of expensive
@@somethinginthewalls388 - is Pallasite olive meteorite similar? I wouldn’t have thought it’s Peridot, but just wondered.
@@rogerhargreaves2272 they're generally more yellowish and can have some iridescent needle inclusions peridot from Earth doesn't have (this significantly rises the cost of the stone). they also have some minor impurities of some rarer metals.
@@somethinginthewalls388 thank you, that’s really interesting. 😀
The blackened crust on a meteorite is known as fusion crust. The crystals in a pallasite are known as olivine.
Ive seen many meteors in my 50ish years. Including one that did the air burst thing and left a persistent green trail across the night sky.
Love this. Great job Elizabeth!
Amazing episode and very educational.. 💛
Excellent! Great job. I enjoy watching and listening to you.
And, of course, I've seen many meteorites, including watching one that hit just miles from me. A friend with a ranch in WY saw one hit, rode out the next day and found it. He said it took days to cool and had it sitting next to his front door. When he moved, the movers stole it.
Elizabeth, you are out of this world.
That cheese was free.
Everyone at JTV is awesome, even the dude in the lab.
Have you had an episode with him using any instruments? I’d like that.
Thanks, this was really great information
I just found your channel. This was a perfect informational video. I just recently got back into collecting meteorites. I just love everything about them. Eventually I'd love to get into etching my own slices. I also want to get my own diamond blade saw to try my hand at slicing some meteorites. Thanks for the vid
My husband recently found a potential meteorite. I have now watched a lot of videos on CZcams. Yours has been the most informative and fun to watch. Thank you for taking the time to share.
Thanks!
I saw one come down in Cumberland co TN years ago. The trail across the sky was an amazing neon green. Could not have been more than a couple of miles from my house at the time.
It's so cool to know all about many kinds of meteorites and how they get their markings.😀🤩🌕 The experiment you did is very interesting.😯👩🔬🧪 It's was cool to see that video of a falling meter, wish I could see one.🌍🌠📹 Thanks for sharing to us and good video.😉💎🌌
This is a great video illustrating the different types of Meteorites that impact the Earths surface. I had a slice of the Gibeon Meteorite from Namibia made into a Pendant, it’s amazing to see the Widmanstätten patterns created by the slow cooling. Peridot in Meteorites is beautiful, it’s actually my birthstone. Brilliant video. Thank you.
Interesting pieces 🤔🦋😍
New favourite episode. Mite have to etch mine that I found🤔
💖SO COOL!THAT IT IS OUT OF THIS WORLD!👽
Highly interesting...
There is a lot of beautiful meteorites in the Arthur Ross Hall of Meteorites at the American Museum of Natural History in New York City.
..." I will show you irony in a fist full of peridote"
Awesome cool experiment fantastic information and knowledge sweet demonstration hmmmm by chance do you have a black diamond so they say are from space only awesome video thank you
can you feel some of the etching? i have this ring and it looks like meteorite ex i can feel some of the patterns. is it real or not and just engraved to look like one? its magnetic and it has inclusions, but the feeling is what gives me doubt.
I recently have taken up the hobby of blacksmithing. Is there anyway of making that iron alloy, or are they only found in meteorites?
Part of getting the patterns is cooling the molten metal EXTREMELY slowly, thousands of years per degree change of temperature. You can make a basically identical alloy, but it wouldn't crystallize properly to get the patterns. Even a meteorite WITH the pattern, if you melt it and let it crystallize on earth it won't have the patterns.
هاذا رائع ❤️
I almost got hit by a large meteorite - it was in No Name Key, Fl, in 1993. Now I can look back on it and laugh, but at the time it was terrifying. The meteorite landed in the water around 3/4 mile north of No Name Key Bridge, but meteorite material was raining down all around us, hitting the street, tearing through the palm fronds, etc. People say that meteorites are not hot when they hit the earth, but we watched them glowing red hot and starting small fires. The one that hit the water, the big one, glowed orange in the water until the color slowly faded away as it obviously cooled.
I found rock like a diamond crystal with different colours and sizes.But I don't know how test if it's a diamond.
didnt you guys have a show on tv where you sold gem stones and rocks i use to watch it all the time you still do that or not
I might have a few
A comète.. i saw this summer...it was blue
❤❤❤❤❤❤❤
Widmanstatten patterns
I found stone so heavy and had a patern
Not yet
If only you knew what was really in the center
It's a Tootsie Roll in the center - duh.
@@hannahpumpkins4359 I was talking about holo earth
@@hannahpumpkins4359 there is a name for it , not mantle core and I read a book on it .. it’s called Agartha
She’s smart
Don’t leave Jtv Elizabeth, your the only cool person on this channel.
🤔
A girl that talks to you like this is worth marrying
She's rather easy on the eyes too
Lol...I was thinking the same. Her intelligence is attractive. Wish I could be like her.
Hence the big rock on her left hand.
Earth core is made out of metal? How do you know that for sure? What repeatable observable experiment was conducted?
Link please!
Good question! They act like they have all the information about certain things and clueless about others. I have found an old pirates treasure of many different things and have taken him into the jewelry store because I'm clueless and so are they. Gemologist and geology and archeology have a big lockdown on us citizens. I was at an upscale jewelry store yesterday when the owner came up in his $3,000 suit and asked if he could help me. I showed him an amazing metal meteorite extremely smooth and I brought it in with a magnet on it. He said he had no clue what to do with this thing and he said it's a cool item but yeah I have no clue. I asked him what school he went to because I'm about to become a gemologist and I do not want to attend the school he went to because they learn nothing! They act like they can only work with cut gems and they've never seen it raw. I'm not kidding! These gemologists are bizarre to say the least.
Because they made it that way! It's almost like we're listening to the makers of these planets. She had a wizard of Oz helper in the background telling her what to do. These guys don't get to have minds of their own, they're heavily schooled in secret cult of knowledge. I'm about to mix geology and gemology together and blow their minds. A gemologist is actually going to understand what a raw diamond looks like!
We geologists are pretty sure about it as we know for sure mass of our planet, crust's density and (i guess ) mantle's density.
All we had to do is calculate estimated density of the core (and we know its volume thanks to geophysics). Best match is iron-nickel composition. And a little bit of sulfur and noble elements.
Also Earth's magnetic pole hints us that its core has to be metallic
@@deborahalbertson8166 - For the love of all that is good, please stay far away from the field of gemology.
Heheh and the earths core is supposed to be liquid molten VERY hot metal right??
PleaSe show me a molten liquid magnet. @@naughtyfins6810
i have a metoerite of may house ..
Pallasite is my favorite gemstone. Wish i could afford to incorporate a big long strip of it down the top of my fuel tank. But at $200 per gram, that accent piece would likely cost 10x more than what it cost to build the bike in the first place.
you forgot baking soda in the water.
I have Real Meteorites
Are they from Uranus?
Asteroid belt and Moon
What happened to Nat?
She left and works with GIA I think
Dh Davis rough diamonds. CZcams. I do alot

Phil Schneider, before his murder said the Alien metals. Instead of 105 there is 150 metals.40 45 metals are Goverment top secret metals.
LMAO!!!!! And CERN is opening a portal to hell, right?
rubbish
enlighten us then, oh special geenyus.
