This HUGE Horned Helmet Sea shell is so amazing!! It would make a great addition to any collection!! This shell was brought up in Indo-Pacific waters by a diver that traveled all over the world for his collection! This shell measures:10 1/2" Long measured on the inside of the shell. It is 7" wide measured inside the shell. It is 24" around the whole shell.There are several holes in the shell. Some are pictured. I will describe them as I see them. The very tip top most spire has a hole at the bottom edge of that spire as pictured. There are 4 bore holes in the middle outside of the shell. Some bore holes are tiny and one is big. There is one hole on the bottom back of the last set of spires that is quite near the lip. There is a small chip in the top most spire at the top of the shell. There is a chip in the bottom edge part inside the lip. there is some chipping along the lips. Everything is pictured except the hole in the last set of spires. This shell is so AMAZING!! It is very heavy and will be double boxed and wrapped in bubble and put in peanuts. I have lots of shells up for sale and gladly combine shipping! Thank you for stopping by!!
