New found specimen roughly 2006 to hit the market have been found in Mali. These specimens are some of the riches nice gems quality, I've seen beside India. This specimen considerable very large, well crystallised, gem quality, water green spherical aggregate associated/rutilated with few needles of lustrous, prismatic dark brownish-green crystal Epidote.
The Prehnite has thousands of micro terminations all over the "Ball" and this specimen is gemmy enough to be facet into a nice gemstone. My opinion this is a very attractive and highly displayable specimen of a species that is often overlooked by the mineral collectors.
