Diggingd 36 Posted January 22, 2019 Share Posted January 22, 2019 Recently I cracked open a geode, it opened up to a great smokey quartz geode with what I thought to be clear quartz warts (for lack of better term) growing on top of them, but on the other half of the geode incased (for the most part) are these orangish brown Crystal's that look almost to be tigers eye (could be completely wrong), I have confirmed these are Crystal's and not dirt, because a few are hanging outside of the Crystal's and I was able to pull it off (to small to tell what it is tho) oh and I forgot to mention, i dont believe the "clear quartz" is quartz because under black light it glows light pink. Any information is helpful! More curious than anything! 1 Quote Link to post Share on other sites
adam 3,120 Posted January 22, 2019 Share Posted January 22, 2019 Likely Calcite. Neat little geode ! 1 Quote Link to post Share on other sites
Diggingd 36 Posted January 22, 2019 Author Share Posted January 22, 2019 Thank you! Do you think that the brownish crystal could also been calcite? Quote Link to post Share on other sites
fuss 40 Posted January 23, 2019 Share Posted January 23, 2019 definitely not tigers eye, it looks like quartz with some calcite. 1 Quote Link to post Share on other sites
Diggingd 36 Posted January 23, 2019 Author Share Posted January 23, 2019 Okay cool, thank you both very much. I'm thinking about having a small piece of it tested by a friend, hes very interested in it he thinks it could be tigers iron because there is a few hematite Crystal's that are growing through small gaps in the smokey quartz. Very unlikely, but I will post the results if we do decide to do it. Quote Link to post Share on other sites
Morlock 1,624 Posted January 23, 2019 Share Posted January 23, 2019 (edited) You can check for calcite by putting a couple drops of vinegar on the suspected area, most likely the large clear crystals. After a few minutes, you should see slight fizzing. Let us know... Edited January 23, 2019 by Morlock 1 Quote Link to post Share on other sites

Tiger iron is made up of layers of tigers eye (quartz after crocidolite), hametite, and red Jasper. There does not appear to have been any crocidolite, now or previously, inside your geode, nor is there any red jasper. 1 Quote Link to post Share on other sites
