- We take a look at carnelian in this video.
I briefly cover the types and colors carnelian found in North America. I'll also get into the formation of carnelian.
Forgive the filmstrip intro music. It seemed appropriate, and made us crack up when editing this video. We figured you might find it amusing for the same reason we did. ;)
There is a full length article about cryptocrystalline quartz on my website.

The article has much more information than could be covered in a single video without the benefit of a full editing suite.

The MOST INFORMATIVE AGATE, CARNELIAN AND CHALCEDONY VIDEO! Thank you 🙏 !!
Thanks for watching. For reference, a deep red carnelian is the most sought after color. Red carnelian is highly prized for religious jewelry.
You are a great teacher for newbies to rock identification.
You have some awesome teaching aides! Those pieces are mighty fine!
👏👏👏 I learned a lot. Your way of speaking and teaching is very conducive to learning. I would never have guessed some of those were carnelian. 👍
Terryl Schumacher-Levy , agreed! Dghtr and I = new to rock hounding, we did agates when she was young but now she’s a mom and in 20’s = rediscovering lol!
This has to be one of the most helpful hounding video's iv watched yet so much key info all in a short video cheers David Briggs
This video was incredibly informative and helpful. After watching, I went and searched for some in some landscaping stones around my property. I found a couple! They’re awesome.
There’s even very faint water line banding on one.
Great video and extremely well said!! Instantly subscribed!
Thank you very much.
Awesome video again bro.. Love when we find it in the orange and reds.
Thank you, this answers many questions on some exact type stones we have in our (new) MN collection that we were unable to identify until this vid, omg!! We’ve been looking for better explanation on stones/ minerals, it’s amazing how limited and confusing existing info can be, so Thank you 🙏
happy to be a help.
Hey david this is another great video, I truly appreciate the knowledge and just seeing parts of your collection from your area. I have been finding nice carnelian like this in northern Oregon. I love the color these stones range, but mostly I find caramel colored agates, with the occasional deep red or orange. Maybe you could do a video on Jasper i.d. and the confusion of green jasper/ Oregon jade etc, that would be intersting to hear your thuoghts and see some of your jasper collection!
Love that 70's-80's warbly vhs tape intro music! Thanks for the video.Cheers!
I was going for a Jr. High science class vibe. I almost wore a balding comb over wig and lab coat. Almost ;)
Found something like this two years ago on the beach. Was round like a baseball. Was up on the shoreline taking a leak, looked down and there it was
Most enlightening. The different forms are amazing 👍😍
Glad you think so!
Cool, I just found a big carnelian in Sterling NJ. Also a smaller piece that has the chrystal pockets of carnelian in the vicinity of an archaic adz in Hamilton NJ. Being a flintknapper I come across a lot of cool specimens when quarrying for chert, Quartz & Argillite for the research into indigenous regional stone tool making industries. Tks for the video.

Very informative! Thank you for sharing your knowledge.
This video helped me a lot, very easy to follow. I liked your samples. I have a hard time looking at an ugly rock and distinguishing it to be something amazing on the inside. I found a 2lb purple rock and this guy kept bugging me for it, I finally gave it to him and later found out it was an agate. It was disappointing he never told me what I had. I just can't tell from the outside. Thank you for your knowledge, take care. 🐕🐾
Great video David! Thank you for the clarification!😊
Thank you for a very informative video. I had no idea that chalcedony was so versatile. 😍
A “product of quartz “,,agates /calcedony..love this visual info ! And any knowledge on formation and origination is greatly appreciated;)
Thank You for the information helps me to learn more
I just wanted one to go in the tea...I waited all video!
One did. I had to film another take. I'll look for the clip and get it in the next video. 😆
Great video. I find many little ones like the many you have shown in this video. I never know exactly what I have because as you shown they can look so different at time. Great video. Enjoyed the teaching :)
Thank you very much. I hope the cheesy filmstrip intro music wasn't too much. I'm trying to bring a little bit of my sense of humor into my videos.
@@DavidBriggsAdventures I enjoyed the video very much :)
nice video good info
Amazing video! Thank you so much for all the info.
I’m new to the world of gemstones, and find myself particularly drawn to carnelian. I’ve been reading all kinds of contradictory information as to how red/orange agate is different from carnelian, to the point where some people were saying that “regular reddish agate” is sold instead of carnelian. 😱 I’ve been having a hard time keeping up. I have a few pieces of orange agate with pretty evident parallel stripes, and others with no stripes but cloudier and with some darker inclusions. Shall I call them all agates or all carnelians (just kidding!)?
I’ve noticed that most ancient Egyptian and Roman carnelian artifacts have very few stripes (bands?). I guess it might have been a matter of preference, or they might have found stones with fewer bands. I know, I’m off on a tangent. It would be really cool to figure out what type of agate they bumped across more frequently.
I’ve also subscribed. 😅😊
Excellent
Any ideas on how to identify chalcedony? I think I found some but I’m in MA and I don’t think it’s prevalent here🙏🏾💜
Wow those were some awesome pieces of carnelians. When you were naming them from different locations had you actually gotten those from that location?
Yes. Gifts from Chefs I worked with around the world. Iran was the hardest one to get.
@@DavidBriggsAdventures oh wow that's pretty amazing and is a story in itself. How unique.
Hello my family own a mountain full of carnelian rocks, since me and my sister were gem enthusiast. We can differentiate it immediately, that is how the size of carnelian everywhere in the mountain except my relatives didn't know yet. How much do you think it costs, once they knew about this, they might start a quarry 😢
I LOVE THIS SO much! So which one is more valuable? I find these all over Northern California ❤️
Since it’s found mostly everywhere, I’m guessing that the stone (raw)
by itself isn’t very valuable- unless it has value as a specimen (so if it’s combined with something unique/ in host rock) OR it has potential as a polished stone for jewelry/tumbling (so color, clarity, unique patterns, lack of fractures?)?
It can be valuable. I tumble out samples to determine highest and best use. Rare specimens happen. Usually at or near the source of an extinct hydrothermal vent. I keep those as found. I usually collect every carnelian I can pick up because there is value in tumbled stones. I always keep a few really fine examples to hand out to clergy when I'm at events. I once gave a nearly clear ruby red carnelian to a visiting Islamic Clergy Member. First time giving one to a Muslim Minister. (Sorry for not knowing their title.) He was deeply touched by the gift. I had no idea of the cultural significance. I just knew red was prized, and he was a carver. He explained what such a bestowed gift meant in his faith and cultural understanding. It was a pretty interesting meeting as we chatted about carving and gem hunting. He was the first Iranian member of the Clergy I met, and I was the first gay person he ever met. I appreciate value, but I get so much more by the simple act of giving.
Just subscribed. Quick question. I live in Thailand, near Burma. I like to take walks around the public wooded areas and have found some carnelian, agates, etc. Is this stuff worth anything? I like it as a hobby but I am wondering if I can make some money on the side too?
Nearly worthless raw. Cut stone is always worth more.
make more ID videos! you did amazing!
Thank you. I'm working on a few ideas but I have to get some saw time in. My saw is pretty loud so I try to give my neighbors a break. Everyone is leaving for the season so I can fire the saw up soon.
I've got some stones very similar to your larger specimens but in colors ranging from orange and caramel to gray with brown or black stripes and some are even green/yellow or have no color besides staining whatsoever. I was under the impression they may be nephrite jade? My collection is from the upper-most part of northern California btw.
Oddly enough, my home is on the norther edge of the range of the stone you speak of. It's a unique stone in that it's slightly harder than a 7. The Asian Gold miners that worked this area discovered it. They worked several pieces that are in the Oregon State Geology Museum. It's so close to Asian jade that only an electron microscope or an XRF test can tell the difference. The miners we mentioned saw the value in what they found. The other miners thought they were nuts. When they finished working their claims, they loaded their gold in the bottom of their boats and laid the "worthless ballast stone" on top. When accosted the bandits would search being general bullies, and only find very sharp shards of stone. Finger cuts are discouraging.;) They made it home with gold and MASSIVE billets of jade. Talk about double happiness.
So the Moganite content varies accordingly! So you could have an agate which is 20% Moganite and you could have one with 80%, would that be a fair observation?
Great question. This ranks up there with the slight chemical difference between American and Asian Jade of the same appearance.
The in-situ Fourier transform infrared spectroscopy shows that while the thermal responses of H2O and OH in moganite display similarities to agate, the spectra are not completely identical. Absorptions in the O-H stretching region reveal that dehydration and dehydroxylation is a multistage process. Although hydrogen loss starts below 400-500 K (127-227 °C), hydrous species may well remain in moganite even at 1,060 K (790 °C).
Thanks for watching ;)
Thank you! much appreciated!
How does sprayed coffee tastes?
No different given it's sprayed with water dipshit.
Could have sworn I saw one of the little ones drop into your coffee mug😂
It nearly did. lol There I was trying to be all smooth and making a totally awesome "round the world" point, and "PLINK" 😃
You can't find them in southwest Pennsylvania. Basically, you can only find basic leaf fossils there. It's a desert.
I still don't know what I have. Can I send you a pic😁😜
A LO QUE HE LEIDO EL ROJO, O ROJO OSCURO ES EL QUE. MAS HARA EFECTO, O SEA SERA MAS EFECTIVO.
Say friend... why are you spritzing water over your coffee... screw the rocks... save the ☕
Thanks for watching. I really enjoyed making that video. I was channeling my inner George Carlin. Things we share in common no matter how distant our origins.
👍👍❤️❤️❤️💎
Love yr attitude I do it cuz they r pretty lol
We show people that none of the superficial labels applied to the shell we wear in this life matter in deciding to explore nature. I thought a world of carnelian was a nice comparison.
