Can any of you tell me what this is?  A gift from my father when I was young.  He traveled all over the world so his location does not help.  It is about the size of a large hand.

Hi Carol, welcome! That is a very nice specimen. Steve may move this post to the Mineral and Gem forum as it was accidentally misplaced in the wrong forum here, but I wanted to help out anyways. For future mineral id info- post rocks and minerals here:https://www.detectorprospector.com/forums/forum/51-rocks-minerals-gems-geology/

Anyways, my guess is a type of hematite (iron oxide crystal) known as specularite.  There are better photos that better match it on the internet (google specularite or look here: https://www.bluegems.com.au/shop/minerals-jewellery-gems/a-hematite-and-quartz/), but minedat has good physical info about it.


Glad you like rocks and minerals too!  😀

Almost looks like Silicon Carbide but with less colors.  I hope someone knows what it is.

Yes, there are many dark semi metallic minerals that can look like this. It is maddeningly familiar but I can’t quite put my finger on it. This chromite is close, but still not it. There are some hints of color to the black that hint copper ore like bornite, but that does not quite fit for me also, not colorful enough. It needs a closeup and very sharp photo, that would show the actual crystal habit or form, to narrow this down.

Any rock that black I would see it it attracts a magnet

And give it a good scrape on a streak plate. Still bugs me. If I was looking at it with eyeballs it would probably come to me, but the photo obscures just enough that it is not clicking for me.

      Out detecting the other day and had a signal on the Monster that sounded like your typical hot rock but when I dug the hot rock out it didn't look like my typical hot rocks in this area?  So I took the time to flip the rock over and ran the coil over the other side of the rock and the Monster said GOLD!  So after some scraping I see nothing and I'm too busy hunting and throw the rock in my pouch to bust it open later at home.  Needed to go into my pouch for something tonight and found the rock I'd already forgot about and scraped the piss outta it and saw nothing, ran coil over scrapings and the rock and still a gold signal but no sight of gold?  Took rock inside and took the steel wool to it and finally saw the glint of a little gold so proceeded scrubbing cautiously and found the little flake.  This guy almost got away.  Moral of the story...if it sounds like gold you might want to pack it home for a THOROUGH check.....

      Found this brass tire stem and cap down deep. I don't know what it is off of or how old it could be. Strange it was in the water.

      Meteorite or rock?

      Found this today kind of looks like possibly a Chromite meteorite but not sure so hoping some one could help. Browsed some pictures of
      small Chromite meteorites on google images and seen some similar.

      Dimension is about 1.5" diameter and about 40 grams heavy.
      Not magnetic checked with magnet and my Garrett Pro-Pointer II detects nothing
      Found in London, Ontario, Canada

      Any help would be great

      Can you tell me what it is? I found this in Central Florida and the only "rocks" we have here are fossilized corals. But it was near the "landscaping rocks" pile people in FL buy and litter their property with, so it could be part of this pile and in that case brought from out of state. It is very heavy and feels solid. 2 corners are chipped and some different yellow material shows through. 
      Thank you for suggestions.
