Collected 6ft deep, 2022. In South Leyte, the arabica there are special. Phenomena is unknown why they have such orange or purple shells. The theory is that a live volcano there is emitting some metals or eroding the upper layer to form the amethystea top; this can be faked easily by polishing off the top layer, therefore I only buy from trusted source with live photos.
