Vivianite - Ukraine classic
Kerch Penninsula, Crimea Penninsula
Crimea Oblast, Ukraine
7.3 x 6.2 x 4.1 CM (cabinet)
price: $350
A very well-crystalized Vivianite from the John Marshall collection, obtained in 1989. This was at one time a great locality for good Vivianites, this one is above average by far with no damage and free standing crystals to 3 CM. The crystals are well-terminated and lustrous, they grew protected in the vug of this Limonite matrix. These vugs were actually the voids inside fossil shells in this iron rich bedrock. The size of the crystals were limited by the size of the fossil voids; this one is especially large and choice. The color is quite dark, nearly black, except with strong light the dark green color is seen. Some of the Kerch Vivianites were unstable and matrix could crumble in a few years. This is absolutely solid and has no issues. Recent finds of Vivianites in both Europe and Brazil have been very impressive yet these older Ukrainian specimens have a somewhat different habit and look. These are of course completely unavailable now and may not be available for a long time - if ever.
