Is this rock JADE?
Found another AMAZING rock on the Fraser river. Now lets cut it down, test it to see if it is Nephrite Jade or Gem Serpentine, and make something from it. In this video you will see me go through the whole testing procedure to determine between serpentine and Jade.

I was lucky to find a small piece of super high quality (nephrite) jade on the Oregon coast last year, about the size and shape of a pickle. I took off the rind, cleaned it up, polished it and sliced it in half to make two cabochons out of it. Ended up making it into a necklace, that's now known as the pickle stone. x) It's actually the highest quality nephrite I've ever seen, it's extremely translucent (looks almost like minimally milky green glass, with the typical magnetite inclusions). Gotta love that stuff.
It's everywhere in brookings oregon on the southern oregon coast, best jade spot in oregon!
Brookings has 4 rivers which all have different quality jade that looks similar but different, some rivers have glass clarity jade and others have way more but with lots of magnetite
@@GoldenBoy-et6of Yup, that's exactly the area where I found it! My girlfriend and I like camping and rockhounding along the southern Oregon coast, and I found several useful pieces but the pickle stone was the best one. x) What river would you say contains the highest clarity jade? I found some more or less good pieces at the river mouth of the Rogue, but I'm sure there's better stuff in other rivers.
As a gemologist I find the refractive index is crucial to identification of jade-like material
I love the fact that you never stop wanting to teach and giving everybody an education on what you're doing I can tell that you love it😂❤🎉🎉🎉🎉 thank you
You should make some of these slabs to hang in a window. Dark days it would look completely different than on sunny days. Beautiful work Dan
Measuring Volume of an Irregular Object: The best way to measure an objects volume is to tare a container of water on a scale and then carefully suspend the object in the water fully submerged using some tape or string. The scale will display the mass of the volume of water displaced. Therefore at room temp (more or less) the grams on the scale equals the volume of the object in cubic centimeters. This is what Archimedes actually discovered.
Why not measure volume directly using a graduated cilinder?
A 1 or 0.1 gram resolution scale will be far more accurate than a graduated cylinder measurement. By definition, 1 gram of water is 1cc or 1 ml (at room temperature - you could correct for exact temperatures, but the effort probably isn't worth the increased accuracy.) So... If you already have a scale that weighs in grams, this method is easy and accurate: 1) First weigh the dry rock alone, in grams. 2) Now place an empty catch pail on the scale and tare it (set the weight to zero with whatever is on the scale). 3) Next add the water tub, and top it off. 4) Carefully displace the water with the rock. 5) Carefully remove the water tub/rock 6) What measures on the scale is the grams/cc's of water displaced. (I wouldn't worry about a couple water drops on the water tub. Each water drop weighs about 0.03 grams, so a couple drops really don't matter significantly when we are looking at a rough density like +/- 2.9 g/ml.) 7) Density is a weight-per-volume measurement, so a divide the dry rock weight by the displaced water weight, and there you have the rock's density. It's faster to do than to explain! ;)
Tip, for easy accurate volume measurement: suspend the object on string and submerge into a partially filled bucket of water, on a scale - the scale will show the weight of the displaced water! (And for whatever you are holding the object with, like a cage or clip + string, you can tare its displacement out by submerging it down to the same line without the object attached). Awesome video Dan!
That's my favorite way to do it, because directly measuring the volume of water isn't as accurate, and this method also works for tiny specimens using a milligram scale 😁 I usually use a piece of my hair as the string for tiny ones
Yeah, Dan, I’m surprised that you don’t have a setup for doing sp.gr. more directly. Maybe that’s not actually a thing you need often. Anyway, fun vid. Love the jade stuff for some reason.
This. Doing the water displacement method can be terrible, imo.
I try and show people something everyone can do, and most likely they will just be doing it once, so they don't need a fancy setup. simple works for a one time thing.
Fair enough! I was a little harsh on my assessment. Carry on and keep doing what you're doing. Love the videos.
I went jade hunting on the Fraser River last summer. Amazing! I also found absolute jade boulders on another river nearby. 😍
Good morning from Bellingham.
Nephrite often contains tiny black crystals of magnetite, the source of the magnetism so often measured in nephrite. Incidentally, I have small bits of Fraser River jade totally free of inclusions, but not as green as shown in the slabs shown here.
Hi Dan, how about giving us a video of the gold rush history of the Fraser River and how they mined that placer gold back in the day from that swift current and if/how they went after the gold in the river bed. I guess regs don't allow it today.....I'm thinking there must be a lot of gold underneath that flow still. Did they ever go after it? Maybe another video about the Cariboo placer gold rush history. Keep up the great vids! Thanks
I love seeing how you use the scribes. Great education Dan. Thank you.
All of your geology and a few other channels on youtube have gotten me into Rock tumbling in my 40's. First batch is going now.
Hey Dan I luv watching u hunt and cut rocks I'm 63 years old and I have collected so many rocks that people think I'm nuts but rocks are my hobby I have so many different colored rocks I've petrified wood I have fossils I have arrow heads I just wish I could show u but I live in West Virginia anyway i wish i new witch ones were worth money but i don't and probaley will never know but im going to keep on collecting them because of the beauty of them and one day when i pass they will be tthrown out for some one else to find them and hopefully they will enjoy them like i do ?
Why would someone throw them out.. There's a few apps on the app store that can help you identify what kind of rocks you have.
You are just AWSOME Dan!!! You're one of the person i wish to meet one day, soon hopefully !! You got siuch a huge knowledge that you give through your experiences!! Just REALLY REALLY LIKE YOUR PASSION !! THANK YOU SO MUCH !!
I ordered some ocean picture stone & black jade from Dan & I can’t wait to start cutting, shaping and polishing ❤️
And a geology lesson of the day!
That stuff looks so nice I just had to buy a chuck of it from ya, stoked to see it up close.
This was awesome to watch for someone who loves gemstones and colored rocks. Thank you so much.
Beautiful find Danno. I would cut a few 1/8 " slices, bond them with silver solder, & make a nightstand light.
Always entertaining, and love the geology
It is much easier to weight the water that got out than try to guess the volume based on such scale. Scales on such containers are often quite a lot off.
Hello Dan: Jade is so flicking beautiful. You are always a winner. Thanks for another awesome video. Regards South Africa 🇿🇦.
Dan, you’ve had me on the lookout for a variety of minerals and gemstones in Arizona and I just learned that we have a lot of high quality red jasper with bands of hematite! I immediately went out to my rock collection and happened to have a fist-sized piece of the stuff! 😂 Who knew?! Thanks for sharing your lapidary and prospecting knowledge with us!✌🏼
We had the Polar Express blow through southeast Nebraska with snow and -20(F) actual temperatures. Pipes froze - AGAIN! A little shop time is always a good alternative.
This was fascinating! More please!
Nice work, Dan!
Winter prospecting is where I have found my biggest nuggets! A little snow doesn’t make the gold disappear!
Quality production....Great job Dan🤝
Awesome! Thanks for the explanation!
Thank you for the video. I like learning the process.
beautiful jade
Kool Dan... Wish I was in your classroom. I'm an old "Tinkering Geezer " but my backyard is about as far as I go.
Dan. Thank you
Great video, thanks for teaching....some beautiful green there.
That was cool. Shane about the flaw in the stone. The thin pieces that the light went through could be turned into tiles that are back-lit.....that would be epic and seriously expensive......Worth it though. Cheers Danny Boy. All the best to you and your family.
It is so cool. At 13:30 it reminds me of the universe with stars shining. AWESOME..
Good Morning Dan
Hey Dan, Just letting you know there is a youtube channel called Gemstones (if you wanna look it up) its a great channel that talks about many kinds of stones,minerals and other types of stones you might be interested in, they recently did a video on Jade and many kinds people use as a look alike or even stones they dye to look like jade. Thought you might like the episode because they also tell other differences between Jade and serpentine. Keep up the great stuff :)
Great video Mr. Dan!
Thanks Dan!
AWESOME!
those sparkels vains looks like gold !
Pretty honest results!
That is a beautiful piece of Jade. Just gorgeous!
Very cool Dan!
Dan you are a very good educator for the Rockhound industry!
I live in the Okanagan as well! I just started prospecting this summer, I love your vids! I hope to see you out some time!
Much love from Texas!!😎😎 love your content!!
One of the best educational video makers on jade
Great video
Thank you Dan for sharing this delightful video six stars brother
Thank you for your thoroughness! You're right, either way, that is a fantastic stone!
You got snow, we have new snow today, too.
There is a lot of Nephrite jade where I live. Dan should come visit me sometime and I will take him jade hunting! Also jasper and serpentine are abundant. That is a beautiful stone with an interesting pattern internally. The jade I find where I live doesn't have nearly as complicated of an internal structure or inclusions like that. I love the variety of jade. Dan should also do a video hunting/mining Cassiar jade up in BC.
Learned a lot from that. Enjoyed
Beautiful,.,Tkzz for sharing,.,peace
You are so admirable personality and provide right information about jade
5:24 holy smokes that's beautiful!
well i did need to know about the from dave that information is Inportant to know and understand. thank you for sharing the adventure and information great stuff.
What's up Dan! Got to love it all.... mother natures miracles are so beautiful, you're in a great area for fantastic examples & circled with great minds..lots/most also have Prospectors Beards lol!..love it all! ⚒️⚖️👍🏔️✌️🤠
I really need Dan to come rockhounding with me so he can check out the amazing stones I have been finding!
Good evening from Copperhill Tn.
nice specimens Dan
The larger the piece the more accurate the measurement , ASSUMING the piece is free of cracks and voids and is the same mineral throughout . Of course you could always cut an exactly symmetrical cube of the material , measuring precisely 1 cm per side , and just weigh it . Water weighs 1 gram per CC ( cubic centimeter ) , so Nephrite should weight 2.9 - 3.02 grams if it is exactly 1 cubic centimeter . Since precise cubes of stone are not easy to come by , you get the volume indirectly by measuring the volume ( or weight ) of the displaced water . Then you weight the same piece when it is dry , dividing the weight by the volume . That is gorgeous stuff . Looks like you are looking up at a rainforest canopy when it's backlit . I would love to make some lamp shades of that stuff .
Greetings from the other side of this gem Thanks for the very interesting post as always 👍🏽🤙🏽🖖🏽
Your jade material looks exactly like the stuff I'm pulling out of the creek near where I live, it makes sense because I'm just south of you in Washington state.
Light scratches at level 6, with deep grooves at level 7. Beautiful stones regardless of the outcome, (still watching). OPS is great too!
Good stuff ❤
That's a lot of saws... Very cool.
Mine is Green/Black combo of carved owl. Cut slices of leaves are pure clear color of Jade made into a tree. Volcano poking through a Reef. Easy in the Pacific. And Old Reefs are in Colorado in the high mountains and other places in the west.
Nice green rock 😀
✨✨✨✨✨✨ Depends on the Jade 🤟jade hardness is 6/7 Good test
Hey Dan, Jade or not the rock is still interesting ! This planet we live on is simply a mass of interesting. thanx Dan Take Care
The Imperial Jade Standard (carving grade nephrite) greatly overshadowed BC serpentinite. It's a hard, durable, highly translucent and excellent lapidary stone. It's widely available along the Fraser River. Much of BC is serpentine in contact with other host rock types, but only serpentinite is formed in the absence of calcium. In BC, nephrite can occur in one of two ways. The first being serpentine in contact with a calcium rich mineral (eg) rodingite, listwanite. Technically a pyroxene. However, BC is a subduction zone, thus sedimentary (or otherwise altered) pockets of mud from ancient oceans may be uplifted to show at the surface as lenses between contacts. Technically, this is an amphibole and the greater process governing the volume of nephrite in BC, usually indicated by asbestos in one or more forms. Jadeite though similar in formation, is chemically different.. entirely. It is a combination of sodium and aluminum, thus a pyroxene, while nephrite is calcium and magnesium as an ultramafic amphibole. Although scratch testing and specific gravity tests are very good aids for ID, they're not singularly definitive insomuch as totality in a point score system. The nephrite at Jim Creek is harder than the serpentine, but softer than the serpentinite, especially stuff that's high in chromite. Up there, nephrite scratches slightly below 7, serpentinite up to 7.5. The calc-silicate of the rodingite is much harder at 7.5+, even though it's accessory vesuvianite within is only 6.0 mohs (or less). At my Royal Jade claim, we see all three occurring together. One is a "semi-nephrite" with shredded tremolite, clinozoisite and titanite, and is associated with listwanites (quartz-calcite-magnesite). The other deposit, a south dipping band of semi-nephrite occurs between a listwanite on the hanging wall and a clinozoisite-carbonate contact reaction zone on the footwall. Royal jade is the hardest in BC at 7 mohs or greater, despite low translucency and grey(ish) coloration. It polishes to a incredible glistening lustre. The best ID for jade, is understanding the differences between these alterations in situ, as opposed to single factors after the fact with placer boulders. Interestingly enough, Ocean Picture Stone formed by brecciation of listwantite and serpentinite, but the absence of chromium, asbestos and the presence of other minerals resulted in something quite different from jade.
Dan seems like one of those people that literally noone on earth dislikes him. hes just disarmingly pleasant
I would absolutely love a genuine jade ring please.. could you make some and throw on the website 😁💚 I've been searching high and low for a jade ring ✨✨✨
I don’t know what it is but I love it
This marbled dark green gives the slabs an extremely ancient, antediluvian appearence. Just like from a Lovecraft story.
Between you and MBMM's channels I get more information then PBS.
Thanks! Loving the Ocean/Dana Blue, jade videos. Would like to see some Man jewelry come out of your stones.
So the main piece you worked with on this video, passed the hardness test, and gravity test but you still will not say it’s definitely jade. Is there some other test that is maybe beyond your capabilities that would be conclusive?? Great video!
Thanks!
Welcome! And thank you.
Hi Dan, I'd love to see some of this jade cut with a waterjet into shaped jewelry and display pieces. I wonder if there's a waterjet channel somewhere that might like to do a collaboration.
My God Dan that is the most beautiful pieces of Jade I have ever seen! I wish I had the money to purchase it.
Dan as always u ROCK man 👍👍💪💪💯💯
That's a very cool rock.
You rock 2!!!
Cool . I think I found some jade but haven’t done any tests. 😊
i would love a video on boulder jade
Good morning
I've been finding a blue-ish colored jade in Minnesota.
Dan, I don't see measurements on your site for the slabs, they'd be useful!
Nice rocks! I'd like to see how you make stuff out of them.
Something that would sell really really good would be guitar picks made out of the jade you find. I make them by making about 1.5-2 mm thick slices and making picks. They sell really well at $10 per.
you always did want that green lantern ring lol. that power ring.lol.
very nice
Dan we got Black jade here in south aussie at Cowell the Japanese bought the mine yrs ago and i was lucky enough to buy a great stone mounted on a 18ct neck chain ,please check out Cowell jade mate cheers and Ty for the great vids mate
Love it keep them coing❤🌎
Dan The Man 💪😎
I love these lapidary videos. Thanks. This had to be a bear to film.
