Loved this episode. Soon as I saw it I pulled out my Ethiopian opal and Mexican fire opal to study. More of these learning intensive videos.

I love that you have different people to sit on the table but still make the video coherent.. Gemologist or not, you all are very good speakers.. this epi is refreshing to watch. 🥰😍🤩😘

I love opal! I hate choosing “favorite things” because I’m usually fairly indecisive with that kind of thing, but opals succeeded in becoming my favorite gemstone because of how colorful and varied they are! So cool!

What a gem studded cast of characters in more than one way💎

Love this channel and everything geologic. I carve and cab opal and just wanted to add that your Rainbow Fish is unfortunately not a black opal, but a semi-dark opal instead. It's potch would be graded at best an N6 on the Body Tone Scale, which falls outside the N1-N4 range for black opal. It's still a beautifully carved stone, incredible actually, just not a black opal. Thanks for reading. Keep up the great work. You guys ROCK! LOL.

If only you had my 10ct-40ct opal cab collection ! That would be a fun video

Just wanted to let you know that those semi-black opals do have a separate name, being called semi-black or dark opals due to the darker color of potch. As an opal cutter myself I classify them on a scale based on the color of potch from White opal, light opal, dark opal, to black opal. As well as crystal opal if the potch is translucent.

Opals are my absolute favorite type of crystal to collect! I have precious opals from Australia, Ethiopia, Mexico, America, Honduras, Indonesia, Slovakia, and Brazil. I love how varied they are depending on where/how they formed! My favorite is my non-hydrophane 443 carat Ethiopian opal 😊

This is amazing! I learned something today about opals!! I mean, I knew the different types of opals but what I didn’t know that most Ethiopian opals are hydrophane and would stick to your tongue if you lick it. Haha!

My favorite gemstone of all. Because the light/fire is inside the stone. Almost hidden, but when the "light" hits it right...then you see it. Kind of like people.

I love, LOVE opals! My Honduran Matrix opal is definitely a star in my collection, though I also have some gorgeous andamooka. Boulder opal has grown on me, I didn't appreciate them as much at first. I have never heard of jelly opal before and I am absolutely in LOVE with them now.

The opal rainbow fish is a true piece of art ugh I wish I could have one

Opals are some of the most beautiful things nature has ever given! Awesome video!

This is amazing! I love opal and have been collecting a lot of Australian boulder opal specimens this year!

Man, black opal is my absolute favorite gem. It’s so beautiful.

October's birthstone: Opal.. Also a beautiful name for a girl. I love opals. They're just like Christopher said the perfect rainbow stone. I noticed that you guys didn't feature black opals from Nevada; they're just beautiful and one of my favorites among all the opals.

Love this episode as I've just done the GAA Queensland opal course. 100% my favorite stone

I love these videos so much , have a nice day :)

I love my black opal ring more than my diamond by far. 😃

I want an entire episode of Elizabeth licking different stones..that would be dope...

Great job with the sound balance on this video!

This is so awesome for me, I'm very excited to learn more about opals.

I appreciate the lick test info. So cool.

Wow, opal!!

Super glad I found this channel so now maybe I won't get ripped off when I'm buying different rocks and gemstones and crystals and all this stuff! Made the mistake the first round quite a few years back buying a lot of stuff from China thinking I was getting the real deal when what it really was, I believe was glass and maybe resin made to look like crystal quartz etc. I definitely learned from that

This was probably the best video on the entire channel.

Thank you for the video !!!

That was fun the orange fire opal was my favorite.

Opal is called the queen of gemstones, but I say it is KING.

Been binge watching this channel. Love your work!

Hyalite is one of my favorite gems of all time.

I enjoyed seeing the patterns of the Yowah Nut. Thank you for making a video focusing around many varieties of Opal.

I didn't think I was much of an opal fan but learning about all these I'm actually rather intrigued. Didn't realise they come in so many Colours. Some are really pretty! I might be converted haha

love your channel, so fascinating to watch as someone who has always loved gemstones and an aspiring gemologist! look forward to your next video ~

This video about opal is very interesting🤔 and it's perfect since it's October 🧡🎃 and my brother's birthstone, his birthday was yesterday.🥳🎂💎 There's so many types of opal that I learned and one of my favorites.🥰💙💎 It's odd that you lick👅💎 them for testing. Thanks, good video.🙂

Very cool and informative.

I want to know more about the orange piece!

I have _three_ favorite hues: green, orange & purple - all preferably in deeper shades; tbh, I love _all_ colors, but those are my top choices. If I'm selecting something in a different hue, I choose the deep jewel tones. I also have a very short list of metallics: copper & silver. So I _totally_ get the passion for opals. I've the same for opals as well & emeralds (my "birthstone") & topaz & amethyst. Geology rocks. 😊

I swear this would be my dream job❤ (with the exception of archeology)

Awesome video so many different tastes so much knowledge love the one that stuck to Elizabeth’s tongue 😂 such beautiful stones awesome awesome thank you all

Wonderful:)

Nothing beats opals

Opals rock! I hope to get more. There's so many opals Fire opal can be Yellow, Orange, Red, White and Blue. Opalite there's two kinds. The natural one that's green and opaque and can have chatoyancy I believe. The second kind is the synthetic glass that looks rainbow and is incredibly dirt cheap like 1 dollar or 5 dollars There's Opal With dendritic inclusions which gives it the name Dendritic Opal There's also Peruvian opals which I think are common opals I've seen sky blue, peachy baby pink ones, green, Turquoise and lime green ones and they can even be stripped with Carmel and or can have dendritic inclusions . I'm sure there's others too :) Some color opals like common opal can have cat's eye chatoyancy. and very rarely some opals can have both opalescence ( Play of color ) and Cat's eye Chatoyancy and the rarest opal is Star Opal! Only found in Idaho and they have play of color and a very distinct asterism which is caused by the diffraction of light from imperfections in the arrangement of silica (SiO2) in the stones. it can be any color and it's extremely rare. It can be 3 rayed or 6 rayed. I hope to get one one day. I really enjoyed this video and learn some different opals :D

I like when she says “lick”

Another cute video people!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Thank you

That ring is SO beautiful. I would feel like a goddess if I wore that

The back of the Yowah nut opal reminds me of abalone shell

I love this video. I have fire opals, black opals, boulder opals, and Ethiopian opals 🥰.

Nice admin!

Opals are best! Screw diamonds and the other peasant stones~

I too have caught opalidis. Forever addicted hopeless in ❤.

Now it's a super spreader opal haha.

Great overview of opals! How about fire opal vs precious fire opal?

Hi JTV, great video! I'd love to collect opals someday, they're probably my favorite gemstone. How much would a sample like the one at 13:00 cost? Seems extremely expensive looking.

great video i would have like to see some Louisiana or Nevada opal tho

Very talented

Collect black opals 🤤 loveeeee themmmm!!! my husband and I got a custom engagement ring so we could get a black opal

💜💜💜💜gorgeous, my birthstone, love the black, purple, and blue. I've got the rainbow type.,my daughter and I collect

Suddenly have a burning need for jelly opal!!!

Opal, my birthstone 💎

Watching this from my underground house in the opal capital of the world. Coober pedy..

Nice

So I have a brown rock that looks slightly like quartzite or maybe even… feldspar. I found a ton of irony quartz in that area. However after I shaped this one, It now has a ribbon-like opal effect on one corner of one side. It was found at the bottom of a lake in Idaho. Just curious what I might have if there’s any gem experts that can tell what I have just by that description, that would be rad! Lol love your videos by the way, I’ve learned a lot already. Thank you ❤️

I just got a tiny .25 pear shaped tanzanite thats supposed to be jtv old stock. The polish is just a tad heavy and the lines arent perfectly straight. They do however meet up perfectly under 20x . i will end up hitting it with 300.000 grit rouge but its spectacular!

I missed u guys, don’t know why youtube doesn’t recomen u anymore :(

New stone I gotta find. Chinese letter writing black opal

I love precious Opal a looooooooooot

Ople is the best. I just can't get over my mama saying that it's bad luck to wear Oples that were not a gift. Where did ople and bad luck come from???

Black opals have black potch. Light to dark grey potch are termed Dark opals.

I want ALL OF THEM

Nice information, please, what kind of beautiful stone are you wearing?

Black Opals are my favorite to work . I buy rubs. A window is polished into one side to see any play of color . A gamble for buyer & seller. Win some lose some. Takes lots of practice with cheaper rough 🙋🌷🐥✌️♥️

Oooohhhh

wheew thought my jeweler hated something I said when he told me to lick rocks 🤣🤣🤣

So I had a small opal that would change color with temperature, when it was cold it would appear milky white with faint rainbows and when warm it would be clear with the rainbows more visible. Did I have a real gemstone or something else? I was hoping this phenomenon would be mentioned but it wasn’t so now I’m wondering if my opal was even genuine?

I have a Blue and White Opal/Black Tourmaline/Pyrite sphere

I forgot to like subscribe and ring the bell. Oh well maybe next time.

Most of black opal is found in lighting Ridge. And there are more people from different countries mining for opal in lightning Ridge than Aussies.there is also dino fossil, pine cone, yabby button and many more opalised objects.

i have a big fire opal that is more red then orange. i had it as a gift for determining some stones for somebody. i chose it because it looked like a strepsil candy for your throath. later someone held it to a lamp and i saw it was opal because you could see some lights in it.

If you don't lick rocks are you even a geologist/mineralogist?

Where's the large faceted fire opal from?

Can doing the lick test effect the color since saliva and bacteria enter the stone, similar to yellowing teeth?

😍👍

great great video, what is the best way to contact you guys if im interested in gems selling or buying them? thanks a lot this video really helped

I like stone opal my favoret jemtone

This was fun! Does the opal taste good? Lol

Rock lickers unite!

Not me licking every opal specimen I own...

I have a really weird question for the smartest most knowledgeable geologists out there. Is it mica inside an opal that give it the color? And, let me just say, I love your ring,

Wow, that opal after concretion is so pretty 😍 almost as pretty as Rob 😏 he's always a cutie and very fun on camera

Please you Give the price of ea stone

I had an opal pendant and I exposed it to a UV light....it cracked in half. Is that normal?

How do you like the beach?

I’m an opalholic!

Good stuff 👌 A non matrix opal is a mineraloid silicate, You never mentioned koroit, Nor Brazilian opal, Nor wood opal, Shell 🐚 fossil opal, Indonesian opal, Dentric opal there's more, Oh well, We'll presented video thanks 👍.

I love opals! My favorite is Ethiopian opal. Thank goodness I have such an inexpensive taste I'll try licking one :)

If hyalite fluoresces it actually means it contains uranium

My brother birthstone is a black opal. 12:08 i thought she was holding a diper for a sec

Ahh, today iv learnt to lick stones
