Processed shells to reveal their natural mother of pearl layer beneath the color. Beautiful! Trochus Pearl 1 inch to 1 3/4 inch across approx size. Perfect for mirrors, wreaths, wind chimes, picture frames, shell flowers, shell layer sculpture figures! This shell is limited only by your imagination. They are natural and have slight differences in stripes and spots from one to the next ! I have tried to show that with the picture. Some of the edges are ruff. We also have a wonderful assortment of thin sliced agates available that could be combined with these or used as bases. WOW how beautiful that could be. . Stop in and visit our e-store for many more great choices. Will gladly give shipping discounts and or ship internationally.---------If you add us to your favorites list you will be updated by e-bay when we list new items.
