_small.jpg) | Purple Coquimbite, dark brown Romerite, white Alunite. Light brown is discoloration. These species are sulphates and are water soluble. Do not wash with water. This on has the discoloration from being out in humidity so the min bid is only $5. Still do not rinse in water. Still an inexpensive good reference specimen with purple Coquimbite and a nice cluster of dark brown Romerite. These came out from a find in Peru in about 2015 and available but seldom seem any more. I got several flats at that time. ex Dana Wilson MD collection. |
