These all natural shiny smooth marble cone shells are from the predatory sea snail CONUS MARMOREUS. Each shell is approximately 3 to 3.5 inches long and each is a little bit different and unique in color and pattern. These shells are very heavy and sturdy for their size. Like other cone species, conus marmoreus when alive has a venomous sting and care must be taken when collecting these shells. Photos are stock photos, you will not receive these exact shells but ones very similar. These items have all been legally and sustainably harvested. Out of country buyers my apologies but due to US export law, I am not able to ship wildlife product out of the United States.
