6hhjdns ((JAROSITE on GOETHITE)), duplicate, do not bid on 11, bid on 23 | |
Here is a fine damage free large specimen from the Tintic District of Utah. A large mound of Goethite which shows on all sides. One the brownish black Goethite are sparkling crystals of brown Jarosite. On the back it looks like it could have some casts of Gypsum. At the least the look is different than the front. |
