Very sharp transparent and bright green Octahedral Fluorites are in an esthetic cluster. The main crystal is very well isolated and absolutely perfect which is quite rare. The matrix is all crystallized milky quartz that makes a good contrast with the Fluorites. Riemvasmaak octahedrons are highly respected and among the worlds best, they have been found sporadically for about 10 years, currently there is no new production. Choice pieces of this quality can be very expensive, however, this is especially reasonable from the last good finds in 2014.
