This mine has produced what are clearly some of the finest quality Vivianite specimens ever seen. This piece features absolutely beautiful, lustrous, gem quality, emerald green, sword-shaped "textbook" crystals of Vivianite with minor metamorphosed Sandstone. These are some of the best quality Vivianite crystals you will see from any locality, hands down. This piece is in very good shape. I have never seen specimens of this quality, color, luster and gemminess before, not only from Bolivia, but virtually any world locality. A super overall Vivianite specimen from this unusual new find in Bolivia. Ex. Brian Kosnar Collection.
