nationalbank Posted February 16, 2018 Share Posted February 16, 2018 Last month I posted a question about an item which turned out to be gypsum. I hope you might be able to ID the following items I've posted - really have no idea what these are. One is possibly a piece of Obsidian, another maybe a rose quartz as well as a few other pieces of quartz. Photos aren't as good as I'd hoped and I can always upload detail shots. My sincere thanks!

d_day Posted February 17, 2018 Share Posted February 17, 2018 1, 3, 4, 5, 7-11, 16, and 21 all appear to be quartz crystals to me. 6 looks like azurite to me, but the lighting isn't very good. 12 is probably obsidian. 14 looks a variety of tourmaline called schorl. 15 looks like a hunk of travertine 18 and 19 appear to be varieties of pyrite 20 is a small geode The pink stone labeled 23 looks like Roseville quartz 24 looks like small schorl crystals in pegmatite 25 looks like limonite after pyrite 28 looks like fluorite All of these are of course opinions and not definitive answers as identifying minerals from photos alone is extremely difficult.

d_day Posted February 17, 2018 Share Posted February 17, 2018 Ack, typos. 23 looks like rose quartz. Quote Link to comment Share on other sites More sharing options...
4meter Posted February 18, 2018 Share Posted February 18, 2018 (edited) I think d-day nailed it. My take on a few are: # 5 looks to me to be purple Fluorite, # 15 might be pink Orthoclase feldspar, # 17 looks like the mineral Stibnite, an ore of antimony, # 22 looks like another piece of Tourmaline (Schorl) #25 could also be Galena an ore of lead. Very nice collection of minerals Nationalbank! Edited February 18, 2018 by 4meter Quote Link to comment Share on other sites More sharing options...

Very nice collection of minerals Nationalbank! I think you're right on most of those. I didn't zoom in on the second pic of #5 so I missed the cubic shape. 15 does indeed look like feldspar, but it also looks an aweful lot like travertine. Specifically the orange calcite out of Mexico. Still, I think you've bagged this one as well. I think 22 is actually the same stone as 14, oriented differently. and 25, well galena is the name I was searching my brain for when I came up with limonite. Again, I think you've got it. They can look quite similar, but the color and luster are right for galena. Quote Link to comment Share on other sites More sharing options...
nationalbank Posted February 19, 2018 Author Share Posted February 19, 2018 Guys, thanks a million for your help! - and yes, 14 and 22 are the same stone despite my attempt to number these correctly. Quote Link to comment Share on other sites More sharing options...
nationalbank Posted February 19, 2018 Author Share Posted February 19, 2018 D-Day, just google searched azurite and you are correct about number 6. My lighting is pretty bad in that shot. Will post more from this group when I have a chance. 1 Quote Link to comment Share on other sites More sharing options...
