Lake Superior agates are defined as being red, orange, and yellow in color, because they are stained by iron found in the region. Most of these pictures don't look like Lake Superior agates.

Are you 5 years old or something?

lake superior agates come in more varieties than orange red and yellow. these are all lake superior agates. from your lack of knowledge i would assume you are not from the area and simply read a blurb on this type of agate somewhere and then decided to tell the internet what they are, like a 5 year old. should i have coddled you when you proceeded to tell me about something you don't know much about?

I'm from central Iowa, and I find Lake Superior Agates in the rivers and streams here. I also find agates that are NOT Lake Superior agates, because not all agates from this region are Lake Superior Agates.

Take those for example. They are NOT lake superior agates. They are known as Coldwater Agates, named after the quarry they were first discovered in.

How about that one? It was found in Northeast Iowa by my neighbor. It's also NOT a Lake Superior Agate.

Or that one? Still not a Lake Superior Agate, but found in a stream in Iowa, in the area where Lake Superior Agates are known from.

Oh see, now that is a fun one! See, now it has a bit of yellow in it, but guess what. That's just staining from minerals in the river. When I cut a nice face on to another one just like it, it was just the blue and gray colors, because it's a Colwater Agate from the site where I find those.

So, now lets talk about YOUR pictures.

Your first one you can't tell if it's an agate at all. It may be chalcedony, but chalcedony and agate are not synonyms like many people seem to think. Agates are banded. You can't tell if that one is banded at all.

Your second one looks like it's formed in Sandstone, much like the Coldwater Agates I find. I would label it as that if anything.

Your third one looks to be a Carnelian Geode, but not an agate. Carnelian is a type of translucent chalcedony that is red or orange in color. If there is any banding on that one, it's hard to see on your picture.

The fourth picture would need to be cut to see if it was carnelian, agate, or something else, you can't really say based on what you see.

The fifth picture is actually a Lake Superior Agate. Congratulations! You got one right!

The sixth picture is just a blue agate. Not sure what name it would be given. Some people say that Lake Superior Agates can be blue, but I think that's just because they find blue agates in the Lake Superior Region, or ones that have more clear bands that appear to be gray or blue when viewed next to the red and orange ones.

And your last picture just looks to be a piece of quarts that happens to have some small areas of agating on it. It appears to have a rougher crystal structure with only a thin outer layer of chalcedony.

So, if you want to come back and actually explain to me why you think your pictures are Lake Superior Agates, I would love to be educated. I would really hope you don't just come back at me with some random blurb you read about Lake Superior Agates though.

I knew you would have some mega response to that like the scholar that you are. Have you ever heard of a tube agate? Or an eye agate? A simple google search will educate you, but I have the feeling in some way you will continue to believe what you want to believe to make yourself feel better. If you can't tell what it is based on the picture, then maybe sit out the comment section or say "hey thats neat, i don't know what that is." and carnelian agate found in MN...cmon guy. Blue agate? Just give it up, they come in more colors than 3 basic versions. There are gray lake superior agates, white ones, yellow ones, yes even RED ones. I am sorry that they came in those colors and some of them tricked you.

In an effort to resolve this bizarre argument you conjured I am going to drop some links to books about Lake Superior Agates. Your local library is a good way to read about this stuff for free as well.

I knew you would have some mega response to that like the scholar that you are. Have you ever heard of a tube agate? Or an eye agate?

Yep, eye agates have circle bands that look like eyes, and tube agates are basically elongated eyes, that have bands running around the tubes.

If you can't tell what it is based on the picture, then maybe sit out the comment section or say "hey thats neat, i don't know what that is."

Or, I could address that you don't know what they are either.

carnelian agate found in MN...cmon guy.

I'm not even sure what you are trying to say here. Are you saying that carnelians are not found in MN, or are you assuming that carnelians are always agates, so a carnelian agate in MN must be a lake superior agate?

In an effort to resolve this bizarre argument you conjured I am going to drop some links to books about Lake Superior Agates. Your local library is a good way to read about this stuff for free as well.

I am going to assume you have read all these books, since you are referring me to them. Can you tell me which one shows agates like the ones you posted so I can check that one first?

EDIT Btw, I own a copy of this book, which was highly recommended to me by a number of people. https://www.amazon.com/Collecting-Agates-Jaspers-North-America/dp/144023745X/ref=sr_1_1?ie=UTF8&qid=1467953667&sr=8-1&keywords=collecting+agates+and+jaspers

I can see this will not end based on what I say, so literature is probably the best way to resolve this. I would read this one. There are basic images of the different varieties. Google images actually does a great job of showing you the different types as well.

I have the damn things in my hand, I feel like I have an advantage on ID'ing them. I am going to take more pictures, to make you feel more comfortable so that one day people like me can post in peace. I don't expect an apology from you because I don't think you are the type of person to give one when your wrong. Knowing you're wrong though does ease the pain.

Do carnelian agates form in MN? Who knows, depends on how you define them. They are found in many places around the world, MN is not known to be a hotspot for them. I personally was under the impression they were mostly found in OR. Can you find Red Chalcedony in MN...yes. Could some rock hound from OR have dropped a carnelian agate off in MN? Yes it has probably happened. I would say if you have banded red chalcedony found in glacial till from the lake superior region it's safe to say its a lake superior agate. Going out on a limb with that one. I would even go as far as saying if you have banded chalcedony of many varieties and colors from glacial till from the lake superior region you more than likely have a lake superior agate.

Google images is NOT a great resource to learn terms, because if people misidentify things enough, the misidentifications will show up wrong in the search.

https://www.google.com/search?q=water+moccasin&source=lnms&tbm=isch

Take that for example. Mixed in with those pictures of Water Moccasins are pictures of non-venomous water snakes of the genus Nerodia, as well as at least one picture of a Copperhead.

Except it IS a hot spot them, if you are going by "Carnelian Agate". What I initially said was that one of your rocks was just a carnelian though. Carnelian is translucent red or orange chalcedony, which is created by iron in the area. Carnelian very often is part of the bands in a Lake Superior Agates too.

.I would say if you have banded red chalcedony found in glacial till from the lake superior region it's safe to say its a lake superior agate.

Yep, probably, but the one I called carnelian in your album was not banded. I said if it was banded, it's hard to tell by your pictures.

would even go as far as saying if you have banded chalcedony of many varieties and colors from glacial till from the lake superior region you more than likely have a lake superior agate.

I agree, you would more than likely have Lake Superior Agates, but that still doesn't mean that the ones in your pictures are Lake Superior Agates, because, like you said though, they don't have banding.
