I've been following this channel for a long time and I don't believe you guys made a gem/mineral family tree video! I would love a visual example of the groups and species, love your videos!
The color range of opal from blue to red is dependent on the diameter of the spheres. 1,500A is blue and 3,500A is red. You can fit about 20,000 spheres inline and it would be the length of the period at the end of a sentence. I was speaking to a scientist who studied under someone who wrote a paper on how opal was formed. He suggest that opal filled the cavity of slime mold. Also a lot of people think Australian opal was created millions of years ago, some of it was. But there is evidence that some of it was probably formed around 12,000 years ago. The light body colored piece of opal looks to me like it could be Andamooka opal? Great show, Tks!
Trashcan mineral makes me laugh every time. Tourmaline is the most relatable gemstone. That Chalcopyrite/Calcite specimen is so fantastical, it looks handmade. So spectacular.
All kinds of Beryl i would love to see next! It is fascinating that a mineral can create so many different gemstones, some more valuable than others, and other more pretty than valuable. This episode was a good one, love the sparkle of the calcite, and tourmaline is always pretty. They all were. Thank you for sharing!
That was certainly a colorful and shiny episode and contained so many of my favorite things! It was awesome! And you mentioned the ammolite being prevalent in Alberta, Canada, but ammonites and baculites with ammolite are also found in the US, in Montana! Along the Yellowstone river! Ammolite is so beautiful and just amazing in its colors! Thank you for sharing!
I'm loving the subtle changes with Brittany. She looks a lot more cool, relax and confident in her hosting now. She use to sound like she's whispering. Now, she looks and sounds really highly educated
That was so interesting and loving to watch as always! There is something I would love to see more because I've watched the other videos about it but it's about Tsavorite. It's gorgeous, it's resistant, it's rare but so unknown! It's only beginning to be known in jewelry while it's more resistant and clear than emerald we see everywhere. So yeah if you do have more content about Tsavorite I would absolutely love that 💚
I first learned about other stones beside the big three Emerald Ruby and sapphire from you website. I kinda grow up watching JTV. Keep up with the awesome videos guys.
Thank you for introduceing Goethite, I often find this rainbow banding in iron stone geodes and didn't know what it was. It would be interesting to find out how it's formed Thankyou again for a fantastic show
Hi! I love gemstones, I have a question about purchasing a Rubellite necklace. It is a bit more money than what I wanted to spend but do gemstones lose or hold their value?
I have a block of this blackish grey, very spiky crystal formation with tons of tiny reflective surfaces which have a rainbow metallic sheen. It's quite brittle and shards off easily. There's no 'host' rock that I can tell. I'd love some educated guesses, anyone? Tia.
how much do yall know about biogenic opal? it gets identified wrong pretty much 99% of the time. and by my experience cutting a six ray star gemstone is easier then biogenic opal
Can you please do a video on Astrophyllite, Arfvedsonite and Anthophyllite. I have several specimens that were sold to me as Astrophyllite, but then thought (based on several UA-cam videos and hundreds of Google Image examples) that what I had was Arfvedsonite. However, I have since learned about Athophyllite, and I am about 95% sure that this is what I have. I am also sure that the vast majority of what is sold as either Astrophyllite or Arfvedsonite is actually Anthophyllite. It would be good to get a reputable source for a video showing the differences, as sharing the Minedat and Epigem info pages is a bit hard for some of my customers to follow.
I've heard that minerals will actually replace the cells of, (say a fossil or petrified tree)? Is this true or has the wood just expanded to have absorbed the mineral or silicate? Great show, 🫶🙃
It is true! One example, silicification, is a process where organic matter becomes saturated with silica, often from volcanic material. The cell walls of the specimen are progressively dissolved and silica is deposited into the empty spaces. In wood samples, cellulose and lignin are degraded and replaced with silica, transforming the specimen to stone as water is lost.
I would love to see an episode all about dentritic stones, like dendritic quartz, opal, agate, jasper, calcite and even fluorite!
From now on Britney gets to bring her opal with her in all future videos (if she wants to)
I've been following this channel for a long time and I don't believe you guys made a gem/mineral family tree video! I would love a visual example of the groups and species, love your videos!
Fluorite was definitely the first mineral that made me fall in love with collecting! So many amazing colors they can be.

I'd have to say Rob and Brittany are the real gems of this episode. They just keep getting more polished and refined as their experience grows.
This was awesome!! My favorite was the huge opal!! The ammonite was awesome too and that cabochon was amazing!!👍👍😍
I'm loving the subtle changes with Brittany. She looks a lot more cool, relax and confident in her hosting now. She use to sound like she's whispering. Now, she looks and sounds really highly educated
She looked high in this video.? 😂
Love the ammolite. 🥰
Gem woods are the best of both worlds and the apple in my eye.
The ammolite is a dream piece for me

Ammonite is by far my favorite gemstone! And I didn't know that about the volcanic event that helped creating it. Fascinating.
But I also love fluorite! 🥰
Loved this video. All the shiny rocks 💖
Rob’s shirt and the Fluorite are almost the same colours stripes!

Okay Rob, I love the Pokémon reference at the end lol
What a great episode! Thoroughly enjoyed it. Thank you for posting it.
All those colors!!! And totally LOLed at the Shiny Pokemon remark :P
The big opal makes me think of the surface of Venus as in CS Lewis's 'Perelandra'
Thank you for introduceing Goethite, I often find this rainbow banding in iron stone geodes and didn't know what it was. It would be interesting to find out how it's formed
Thankyou again for a fantastic show
The large opal looks like a landscape in Africa
It’s a beautiful piece. I looks like a pastel painting.
Come dig Aquamarine, tourmaline, red Beryl and topaz....
Hi! I love gemstones, I have a question about purchasing a Rubellite necklace. It is a bit more money than what I wanted to spend but do gemstones lose or hold their value?
Wow gorgeous opal...when are y'all doing more geode giveaways??
Straight up have a rainbow jadeite I love it but afraid to wear
✨Think again!~✨ - Britney, 2023
Yes, not even my dogs look that adoringly at me when it's dinner time😂😂😂
What makes the silica form into spheres?
I have also aquamarine and other gemstone 💎💎💎
My favourite there is the Goethite.
Ps. Roberto, you need yo put sunscreen on when out in the sun 🌞 😅

WOW
Still waiting for a feldspar episode!
So pretty 😍
how much do yall know about biogenic opal? it gets identified wrong pretty much 99% of the time.
and by my experience cutting a six ray star gemstone is easier then biogenic opal
"Full on purr-poe" ❤
Now correct me if wrong here but isn’t Australia the biggest deposit found of the full spectrum of color old growth opals.
Yes, most precious opal comes from Australia.

I can’t wait to pronunciation correct go-e-thyte to grr-tite to someone and feel intellectually superior. Muahahaha
