This mine has produced what are clearly some of the finest quality Vivianite specimens ever seen. This miniature size piece features some absolutely beautiful, lustrous, gem quality, emerald green; sword shaped "textbook" crystals of Vivianite with minor metamorphosed Sandstone. One of the Vivianite crystals is even doubly-terminated. These are some of the best quality Vivianite crystals you will see from any locality, hands down.
