2.64 ct. Londonite

This impressive stone, one of the finest of its species, will be the centerpiece of any collection.  Londonite is the cesium rich end-member of the Rhodizite-Londonite series.  And while both are rare, Londonite is by far the rarest of the two - it is found in only in a very limited series of pegmatites in Madagascar.  This particular deposit at Ambatomigaby has been analyzed and found to be some of the purest Londonite ever found. 

So, while any gemmy faceted Londonite is rare, a clean well cut stone in excess of 2 1/2 carats is nothing short of extraordinary.  The clarity, cutting and size come together to give you a museum grade stone that is likely among the 3 or 4 largest, finest examples of the species in existence.  An absolutely irreplaceable stone.  With GIA certification.
