That looks exactly like it chris1956! Now, did they get it right? Don't know but I know what I'll be searching for! More of that type Mohwakite or some Josephine's Crown that is as spot on as that one. The sample is definitely gold color, the photos on the screen look exactly the same in person. I think it is pyrite. I did the pin test, not soft, didn't fleck off, pin didn't want to budge and slid across the gold color parts. Good job finding that one!

My guess doesn’t go beyond “rock”. However, I like reading the mystery unfolding from everyone else. Pretty rock!

Mohawkite and Josephine's Crown look so much alike, I think it will be hard to figure out which it is by pictures. Mohawkite has a hardness of 3 - 3.5 and Josoephine's Crown has a hardness of between 5 - 6. That may be the best way to tell which it is. The short bus! I haven't heard that in a coon's age. Yeah, I'm originally from the Chicago area.

Don't know. rockjunquie has more experience than I do. On your latest photo (top one) the metal looks more like pyrite. Is that the true color or is it more of a silver color? The specimen I have is very silverish but you can see what looks like native copper that shows through the clear quartz pockets. The specimen I have had a clear coating put on it. I have another section of it in the basement somewhere that isn't coated. If I recall, I think it kind of tarnished on the silver part (I will try to find that tomorrow and see what it looks like). Of course, I only have the opinion of one person in the mining department at Michigan Technological University (40 years ago) that my specimen is in fact Mohawkite (we thought it was silver when I found it). Maybe my specimen really is silver? When I look at online pictures of Mohawkite, a lot of them have that pyrite look to them and pyrite can be found in Mohawkite but that could be other minerals that give it that color. Also, keep in mind that Mohawkite does contain arsenic. Holly crap! Take a look at this picture below that I found on the internet. Look familiar? Although who knows if they got it right. www.reddit.com/r/Keweenawrockhounds/comments/k7a21p/500_gram_piece_of_mohawkite_i_got_for_a_steal_at/Looks like you found its twin.

Yeah, I'm originally from the Chicago area. I agree. Pretty hard to tell from the pictures. I will see if I can find my uncoated specimen and check the hardness. 3-3.5 is pretty soft.

In my experience, mohawkite has a white quartz background. The pattern is called snowflake. I have NOT seen it WITHOUT that pattern, which is rare for mohawkite. Apparently, the material that is not snowflake is difficult to cab. Though, I haven't personally tried it or seen it.

I think I meant that, yeah. I thought chatoyant meant it caught a shine....I'm getting on the short bus and going home. (Short bus may just be a Chicago term) tribeunited before you get off that short bus check out a nice piece of moonstone the good stuff is also chatoyant giving a cats eye effect I have some set in a silver ring Cats eye Moonstone in 3 rings not very good at showing the cats eye in this picture but trust all 3 are plus I also have a few others that I cut

hummingbirdstones - I'm glad someone here knew what I meant by the short bus! I'm special! I lived in Chicago until I moved here (Tennessee) a few years ago. So I'm a city girl living in BFE. I still can't believe how early everything closes here.....Where are all the night owls in the country? Everything closes at ten here, I'm just getting started around then! Thanks for the scratch test info! Ok, here are my scratch results. Did not scratch with copper. (Copper left a trail on it) Did scratch with knife, rather easily though. Easily as in, I could deeply gauge it with a knife if I wanted to. Can someone interpret this result? dreamrocks Very cool looking cats eye! Is that blue green or just blue? Pretty!

Here are photos of my uncoated piece that I took today. I did a scratch test today also (got to get one of those testing kits). Copper penny (1956) did not scratch. Zinc coated penny (1982) barely made tiny scratches. Knife blade easily goudged it. Based on this I am thinking the piece I have is closer to that 3 to 3.5 area for Mohawkite but I don't think I have a lot of confidence in this. Just to make this more confusing, there is another mineral from the same mine called Domeykite which is very similar and can even be included within Mohawkite.

Probably need an actual testing kit (would be a good thing for you to get anyway with all the materials you have). Another thing you could do is a streak test. I found something on the internet for Mohawkite that said it should streak grayish-black to brownish-black. Didn't see anything for Josephine's Crown. I read once on this forum that you can use the underside of a toilet tank cover to do this if you don't have a streak plate.

OMG chris1956 - Yours tested identically to mine! Good idea on the real test kit, and thanks for the toilet tank tip. I keep asking my husband, "Do you have any ceramic tile???" I never considered the toilet tank- brilliant! This forum is awesome! Domeykite! Another new name I've never heard of. I was almost convinced I had one of everything, then you have to point out ones I haven't seen. You're the best I'm going to look that one up now. Thank you!

Thanks Mr. 1dave! I'm so glad you're here to guide me towards more informed ID's! You rock 1dave! (Rock pun intended) I agree with you about moving back there - no way! But I miss aspects of it nonetheless! Roosters and crows! Holy cow, you did move to the country! Anyway, thank you! I appreciate your help!

This is for you chris1956 - I found it! Remember when we said we wanted to verify the accuracy of that slab twin you found? If you noticed in that post, when the buyer was asked how he knew if it was Mohawkite, he never directly answered that question? Well, I think we can both be sure now - check this out! Mohawkite LInk
