Unique rusty/purple shell ….  A very special colour … Aberrant purple cowry … Collected at the foot of an old volcano, This coloration is due to the environment where they live … with a sea water containing a hight level of acidity..May be from the sulfuric sources of whater coming from the volcano… Really amazing shell…
