Green Turbo Marmoratus? Polished Shell on stand

Description

GREEN TURBO SHELL APPROX. 2.5" WIDE X 2.5" TALL ON A SHELL STAND.  HAS NAMES WRITTEN ON THE BOTTOM; PROBABLY A GROUP OF FRIENDS ON VACATION.  ONE NAME IS LILY SCHOFF. ONE IS WILSON. I CAN'T MAKE OUT THE REST.  PLEASE ENLARGE PICS FOR BEST DETAIL.  I DO NOT KNOW WHERE THE SHELL IS FROM.  HAS NICE IRRIDESCENCE ON INSIDE AND ARES WHERE THE SHELL WAS WORN FROM BEING IN THE OCEAN AND POLISHING.  I SEE NO CRACKS, JUST NATURAL WEAR.
