4meter Posted March 1, 2018 Share Posted March 1, 2018 I'm think it's Smithsonite, a zinc carbonate, based on the "fibrous" structure seen in profile and the luster of the sample. Try scratching the sample with a steel knife blade; if you can scratch the sample with a steel knife blade its probable Smithsonite. That is a very exquisite sample JoshuaD. Did you collect it yourself? Quote Link to comment Share on other sites More sharing options...

Did you collect it yourself? You may have nailed it. I was firmly in the aventurine camp until I zoomed in. Now, if a knife blade fails to scratch it I'd say it's a chalcedony containing nickel or chrome. Quote Link to comment Share on other sites More sharing options...
JoshuaD Posted March 2, 2018 Author Share Posted March 2, 2018 (edited) Thank yall for the information. I found it in a box of stuff that belonged to my dad after he passed away, along with a few other rocks. I don't know where he got them. I was able to scratch it with a knife pretty easily. I got some closer pics. Edited March 2, 2018 by JoshuaD 1 Quote Link to comment Share on other sites More sharing options...
