Crab Jewelry

I made a necklace of crab claws I found on the beach, but after wearing it for a few months he began to crumble with just general wear. Although the claws are thick enough, one of them has lost the tip and another cut in two. I can not bear them now, because it tends to fall apart when all around my neck, I do not beat around or anything.

Is there a kind of varnish or glue I can quite claws in the mantle, to strengthen them and prevent them from falling apart? You do not know what to do really use. Any advice or suggestions would be greatly appreciated. :)

Try nail polish, Superglue, casting light, or fiberglass resin.The it can be purchased in auto accessories
shops.Be sure to read the safety instructions well and let things dry thoroughly in a well ventilated before reuse. A thin layer of any of the above would be useful to use a nail resin varnish.Clear you would be my choice if it possesses the old cars and it should work.
