I found this seashell on the beach myself.. paired it with this baroque natural color Chinese fresh water keshi pearl and set them both in rhodium plated silver heave back findings... to add some playfulness to your ears with out straining them. The shell is 19mm long and 7mm wide ... (can you see the sand lodged in it?) and as a pair these weigh 3 grams. ID#KDE1141/KDJ440
