Item Description

Click here for a video of this specimen!
A spectacular and superb floral spray of large sharp vivianite crystals is dramatically and very aesthetically set on the sculptural large matrix plate. These surreal large gemmy crystals, to nearly 10 cm, have gorgeous rich blue-green color and stunning lustre. This incredible spray is essentially pristine. A few terminations to the right of the imposing central crystal were contacted against the vug walls, but there is no damage, per se. It's very hard to see the gently bruised tip to a secondary crystal to the left of the main prism. The olive-green bubbly botryoidal matrix is nicely accented with a few scattered sharp, glassy green transparent to translucent ludlamite crystals, to 8 mm. This superlative large specimen is from recent finds at this obscure Amazonas State bog iron deposit, where phosphatic nodules have been opened in recent alluvial deposits replacing organic material, lignite and forest soils (MINDAT). A superb large matrix vivianite from the uncommon locale valued at $2500-5000. We have not seen a better one from here in this size range up for auction but bought a big lot direct, and decided to throw a few to the audience here. I HAVE seen pieces such as this with a few dealers at Tucson and Munich, in particular a European dealer who bought them early and had very similar items at prices of 5000 to 10000 british pounds, for whatever comparison that is worth.
