From the one side, this specimen seems to feature a single sharp analcime crystal perched on siderite. However, this crystal is partially hollow, and although it appears to be a single crystal, it is in fact comprised of many analcime crystals together making up the form of the original analcime. This is easy to see from the other side – this is an analcime pseudomorph after analcime. The analcime is all lustrous and in excellent condition, no damage, some of the dierite crystals are missing. Displays well from either side.
