Nugget Shooter 4,502 Posted November 19, 2010 Here is a cool one for ya...Streak black/greyMagnetic... Share this post Link to post Share on other sites
Bedrock Bob 3,074 Posted November 20, 2010 Damfino. How heavy is that rock Bill? Specific gravity more or less. Gotta have more than streak to ID that rock. With nothing but streak to go on I would call it magnetite. Can you scratch it with a knife? Share this post Link to post Share on other sites
Goldfinger 43 Posted November 20, 2010 I would say it's magnetite also. But I have never seen any with that type of "crystallization".Steve Share this post Link to post Share on other sites
Nugget Shooter 4,502 Posted November 20, 2010 I guessed Magnetite as well, but have never had it officially verified...Will not scratch with a knife and very heavy.Here is a shot in the sunlight this morning... Share this post Link to post Share on other sites

Goldfinger 43 Posted November 27, 2010 Hi Johnno-Hope everything is going OK with you. Not posting as much as you used to.The first one is pyrite.My guess on the second one is mimetite. Hard to get a close up of the crystal structure... More or less went by the color... second choice would be vanadinite.The third one looks like galena.Steve Share this post Link to post Share on other sites
Johnno 58 Posted November 27, 2010 G'Day SteveYeah I've backed off posting a little bit, not from not wanting to but I got a little bit extra on my plate at the moment and I'm trying to deal with it. Funny thing is, the more you deal with it, more gets thrown onto your plate. It's a vicious circle. But I try to keep smiling. Lately I've resorted to toothpicks, it makes me look like the Joker. :( Yes, the 1st one is Pyrite. A really nice specimen. And the last one is Galena, another nice specimen. One hell of a heavy piece.But as for the 2nd one, I have no idea. But I can tell you now if you don't pick it up from it's matrix base, it's like picking up a cactus. Those crystals will penetrate your skin and it's a heavy piece coming in at 5 lbs. It was given to me without any information and I really would like to nail it down.Here's some more close ups for you to ponder over.CheersJohnno Share this post Link to post Share on other sites
Goldfinger 43 Posted November 27, 2010 Johnno-Sorry to hear about your troubles. We all go through those every once in awhile. I've been going through some myself lately. Just hang in there and I'm sure everything will work out OK in time.If it's that heavy, I'm going to stick with my original guess of Mimetite since it's a lead mineral and should be quite heavy like yours is. I've also seen it in that same orangish color although the close ups of the crystallization are throwing me off somewhat. I'm sure some other guys will chime in. Assuming there's not any damage, that specimen should be worth a pretty penny,mimetite or not...Steve Share this post Link to post Share on other sites
Hoser John 1,238 Posted November 28, 2010 Johnno I'd email Crystal in Laguna Beach with a pic,when it comes to the unknown or outta the ordinary they rock!!! Seen a few pieces before but old age and hep c took them memories away with the cure-John Share this post Link to post Share on other sites
Nugget Shooter 4,502 Posted November 28, 2010 Beautiful specimens Johnno! Keep them coming.... From a google search mimetite...This is from AZ Share this post Link to post Share on other sites
Nugget Shooter 4,502 Posted November 28, 2010 How about this from Morocco...My specimen is not so spectacular, but same mineral from AZ. Share this post Link to post Share on other sites
Goldfinger 43 Posted November 28, 2010 Azurite. That was too easy. Nice photo of the specimen from Morocco. Steve Share this post Link to post Share on other sites

Goldfinger 43 Posted November 28, 2010 Not much to go by on this one colorwise- but I've got a hunch. Going to say smithsonite. If not I have another mineral in mind.Steve Share this post Link to post Share on other sites
Johnno 58 Posted November 28, 2010 G'Day Bill, Steve, John and EveryoneThanks for all your input. I will see what else I can find in my box of trinkets, they might not be spectacular and an easy ID but this is a great thread and needs to keep going. I might even take a picture of my waterfall, it's 6 foot high and believe it or not made up of rocks that I'd picked up in the desert. The vertical walls of the waterfall is done in sliced rock containing fossils. Who knows, I might have a fortune in that waterfall... Yeah right. CheersJohnno Share this post Link to post Share on other sites
Goldfinger 43 Posted November 29, 2010 Well- that mimetite specimen is worth a few hundred dollars if it's any help to you. Who knows about the waterfall? You might have complete skeleton of the Archaeopteryx in it. :inocent: Steve Share this post Link to post Share on other sites

Goldfinger 43 Posted November 29, 2010 I have no real clue on it and don't remember where I even picked it up. Have allot of mineral specimens gathered over the years visiting old mines etc.Is it heavy for its size? That's a clue for a lead mineral. If so, my first choice would be smithsonite, then cerrusite.Steve Share this post Link to post Share on other sites
Haderly 83 Posted November 29, 2010 My WAG would be quartz crystals (druzy) over azurite and maybe a little malachite and chrysocolla. These are some really nice examples http://www.nuevomundoimports.net/druzy.html Share this post Link to post Share on other sites
Goldfinger 43 Posted November 30, 2010 Bill is an very knowledgeable rockhound himself so if it were druzy quartz ,I'm sure he could indentify it. That's why I think it's something a little more scarce then druzy. Could be wrong though... Looks like it but......Steve Share this post Link to post Share on other sites

For it's size anyway bout what you would expect.My WAG would be quartz crystals (druzy) over azurite and maybe a little malachite and chrysocolla.
