TXR13CD6: Very aerial group formed by well-defined Copper crystals in stalagmitic growth, with their characteristic bronze color that has not been lost even though it is a very old specimen. A large and sharp Analcime crystal makes the piece even more attractive.
This specimen, well documented and of very considerable size, comes from the Fernando Reyna collection and it is very noteworthy that the Copper crystals are so well defined in such a large specimen.
