Andalusite will always have a special place in my heart because it was the final stone on my Gem-A Diploma exam. With time running out, there was something sooo reassuring about passing the dichroscope over the stone, seeing that huge shift in color, and knowing for certain what gem I had in front of me. What's your favorite thing about andalusite? Let us know!
Andalusite is one of my favourites! I first saw it on one of your live shows and I fell in love with it. It is almost as if autumn was trapped in a stone.
Ooooh, an episode on chatoyant gems would be cool! I always thought “cat’s eye” or “tiger’s eye” were their own types of stones.
Loved this video. Hiyah!!!!
The bracelet was beautiful, love the HiYa explanation of difference in pressure-lol -I had a good giggle. Love how all of you explain things ,so easy to understand. Continue the good work.
I loved the andalusite bracelet!😍
Loved the talk about degrees of metamorphism again and how that might dictate minerals found. That kyanite rough was particularly pretty
I live in central Massachusetts and just north of me is a town where you can just find chiastolite just anywhere, in stone walls that are just leftover, lining the woods, (they used to be marking fields and pastures but inn the mid 1800's the farmers moved to Ohio, etc, and forests grew up where the farms used to be.) Haven't found any yet. Nice low key hobby, looking for chiastolite in the woods.
Love the description of carbon being pushed aside by crystal formation to form chiastolite crosses or trapiche emeralds. Great visualization.
Love the video and really interesting!
I've really been enjoying this channel and love the presenters. Have you ever done a video on the important value differences between readily available commercial cut stones and quality cut (or custom cut) gemstones?
Yay, new episode! I am addicted to your videos! Thanks for sharing this beauty and your knowledge with the world!
the sphere is so cool
Andalusite is so pretty. They have just beautiful color and to have rutile inclusions Is wonderful! The many other forms of it are fascinating!
Loved the Hai-yah! Explanation 😂 Britney is so funny. Love all you guys on this channel. You make it so easy to understand. I love the oval tennis-style bracelet best. Those colours changing are gorgeous! ❤️
another banging episode of this fun pair. it sucks that i have my weed in front of me and i did not get stoned for this as it would have taken it to another level
I love this show so much! I always learn the coolest things. I work at a little mom and pop jewelry store and we have one andalusite ring. I love taking it out and watching the play of light. It's nice to know more about it.
I would love to see more on the trapiche emeralds! That was fascinating!
We'd love to do an all-trapiche episode one day! But, in the meantime, here is an episode on emeralds where we feature our own trapiche emerald: th-cam.com/video/G4HGWycr3Ao/w-d-xo.html
Andalusite - One of my favorite gems. I first learned about Andalusite from your channel. Very impressed with the Sillimanite Thanks for the episode.
The bracelet!
So fascinating as I was only discussing this stone yesterday. Great share. Thank you. 😮
Thank you! I loved the video! It was very informative and I look forward to more of your content. I just subscribed and liked.
This was so incredibly interesting.
What a fascinating stone! Your channel is great because this is exactly the kind of stone I wouldn't give a second glance to without the knowledge (due to lack of flashy colours) but now that you explain what's so special about it, this is one of the most fascinating stones I've ever heard about! Can't wait to see it in person one day at a gem show.
Very good
a great master plan
.I bought a 10.45 carat "alexandrite" online for around $10. I knew it wasn't going to be real. What I got was a sludgy pale brown stone that glints weird golden green tones by daylight. LED light turns it pretty brilliant golden green. Thanks for your video. I'm now pretty sure it's andalusite. I'm thinking of making a video showing it, if I do then I will link it here (if they let me)
Only knew about chiastolite. Now I want both variants in my collection!
Chased down the wonderful flat light you guys use. Cool tool.
i love this channel so much
I love this channel, I plan to go to the gem and mineral show next week because of this channel!!
Awesome! Let us know how it goes!
Have a few of them, amazing the color display from different cuts. Iolite another
Mooooooore pleochroism
Very cool! I realize I have strands of these stones, cut into tiny faceted drilled stones and some Briolettes. I will have to check with a dichroscope! ^*because maybe not but the colors sure match. Also, it is one of my favorites. I kept calling it’a fall colors stone. I actually thought the strands were tourmaline but watching this, I believe they are andalusite.
Fantastic!
I just bought an 8.6 carat andesine, and would like to see a video on that. Thanks
"A lot of Hi-YAH!!" 😂 Thats the technical term for continental tectonic meetings.
And Andalusite pushing the carbon into its orthorhombic system is so cool.
Im wearing a Chiasolite necklace right now ;)
My favourite duo ❤
I like that it takes alot of "HIYAAAHH" to be created
I'm obsessed with dichroic trichroic and color change gemstones they are my obsession so in 2009 they found iolite intergrown with sunstone if you cut it into pieces you would have sunstone and iolite but having them intergrown made it my favorite gem now before it was iolite then sunstone now it's iolitesunstones that they found in India can't wait for another find
Are they blue and orange?
@@cherylj7460 they are mostly but they have the rainbow of sunstone but mostly that orange and then the blue violet iolite but can go to more blue green or more violet purple
Okay I’ve had a large stone that came from the right kind of deposits that I thought was weird quartz but im thinking it might be this I’ll have to go find it!
I was given a lot of faceted cut stones and a decent amount of them look like Andalusite/multi-colored tourmaline. I have a Refractometer/dichroscope along with some other gemological tools, how do I tell the difference?
Very interesting, I love gemstones, minerals, and sparkly stuff. HOWEVER, "Contact Metamorphism" is NOT the correct designation for the kind of metamorphism that forms andalusite, kyanite, and sillimanite. The correct term is "Regional Metamorphism," and yes, it does result from the hyah! hyah! of smashing continents. Contact Metamorphism is the term for a more localized metamorphism that happens when magma intrudes into other rocks, heating and baking an aureole of altered minerals around it.
Andalusite looks like zultanite ♡
Can you please also give some indications regarding the value of the stones you are presenting, price per carat polished stones and unpolished (rough). Low and high. Thank you.
❤❤❤
I bought a matching pair of gems from Jtv way back in 2009 or 2010.
Misty was showcasing them and called them "Zultanite" I think?
I dunno. Maybe I'm not remembering correctly in my old age. LOL
They shifted between a raspberry iced tea color to a sage green, with a variation of khaki in the middle.
Absolutely loved em.
Zultanite is a trademarked name for certain pieces of diaspore, a gem with color change properties. We’ll be covering it in a future episode.
hay ya
Like it's meant to be set in silver or the more modern metals colorful niobium etc. A futuristic sort of gem
I'm still waiting for the gemstone beads episode 😊
Give us time!
@@gems take all the time you need. Make sure it's a long episode.
Love from Australia 🇦🇺 ❤️
Hi channel. We have like this a stone. 100% sure that is Andalusite. But we dont know that the price. Please details
Can you guys talk about Sphene an its proprieties?
Great idea!
Sir I have block stone
I have a gemstone like that sir the color is green yellow redish brown here in the Philippines
Those terrible cuts hurt 😢 But beside that I like the format 😊
Jewelers 1st rule, never touch a stone with your hands. Leaves an oil residual on it. Always use a tweezers, ALWAYS.
We haven't seen any videos by Natalie, where is she?
Natalie left the gem industry to pursue other interests. We wish her well.
Nah. Only positive comments so... I would like other stones over this one. Brown doesn't do it. Love this channel though.
