Agate, Jasper, and Chalcedony: What’s the Difference?

Geologist here ; jasper and agate ARE chalcedony.

This has been very helpful! My parents collected agate but they were all somewhat clear, some very clear with deposits that formed little scenes. Usually pale blue white and cloudy. I had no idea that there were so many kinds. I walk my dog along the river rock beds and today picked up about 10 lbs of jasper, agate, chalcedony and some nice chunks of petrified wood. There is a lot of petrified wood and Jasper among the river rocks. You could spend a day picking through a few square meters and gather 10s of pounds of nice pieces.

I was never a huge fan of agates until recently, when I acquired a flower agate palmstone with lots of druzy. Now I am totally in love 🥰 !

I appreciated the clarifications and similarities you mentioned. It really helped. Thank you for listing and going through the books, the resources, you use. Will be taking a look, thanks again!

Thanks for introducing the very basic things about rocks to identify them . I have so many confusions regarding their identification, now you made it so clear , great video 😊

Thanks for going through these categorational challenges. I am just beginning my journey into true rock hounding, and I’m glad to see that one of the books I am planning to get is on your list. Take care, have fun, and always stay safe. ⛏️⚒️

Thank you so much for taking the time to speak about the difference between the stones. I appreciate your help very much.

Superb! Great quick tips. Will rewatch w my flashlight! Glad to find this handy and informative vid. You're Greattt at this YouTube info. Perfect flow- not slow and boring monotone; glad to find another agate girl!!

Thank you for the detailed explanation. Now if I could only figure out how to identify Jasper from other common rocks. Great video !!!

Wow, this video is so very helpful. I saved this one. Great information, love those books. Thanks for sharing an example of each rock, that really makes it easier. My daughter said your work is amazing! Awesome rocks by the way!

Awesome video with TONS of value for a newbie, so informative well-produced thank you!

This video will surely help me in my rock hunting along riverbeds etc. Thsnks so much!!

I know this is a older video but it was so helpful. Thank you for the great videos you put out.

Keep growing the channel. You're a big help to me. I've even told some people about you.😎

Omg thank you SO much for this! I live in North East Ohio and I find tons of agates, chalcedony and especially jaspers where I am specifically. Great video!

Brilliant, thank you, I needed some clarity about this.

Super fun and informative. Thank you❤

Good vid. I just got started in the hobby. Have a huge piece of rock that I found on my farm that was just tan. After years of sitting outside by the porch I just realized it was not an ordinary rock. Lol think it’s a huge piece of chalcedony. Honey colored if you shine light through it. And this thing is HEAVY!! Thanks for the tip on the flashlight.

Awesome Video. Thank you from Northern California. And yes every state has Geological books for each state. Smithsonian books are cool also.

Thanks for the info. Also, I appreciate the peak inside the books. I’ve been wondering whether or not to get one you showed. Now for sure I’m getting it. You did a really nice job. The other I struggle with is banded chert. So many rocks with similarities 🤪. I’m in WI. I see all of these, all the time. I’ve got sooo much chalcedony in my possession atm 😆. Thanks for the 🎥. Stay Crystal 💫
