GEM natural. A GIANT SHELL. An early rarity in the shell world: one was illustrated in the 3 plates on rare shells in d'Argenville in the mid-18th century. This is a very large Arausiaca of first-class quality. The fascinating pattern of alternating broad and thin spiral lines intersected by irregular axes is remarkable. From an old collection.
Sri Lanka. Circa 1980.
