Ancient Fossilized Shark Tooth Key Ring has three wire-wrapped shark teeth. The small shark teeth are claimed to be millions of years old and found by divers in Gulf and ocean beds off the coasts of the United States. Blue, purple and copper-colored wire used for wrapping shark teeth. I have no idea what shark species type the teeth are, so including this item in Mystery category.
I used turquoise-colored green faux suede, six pony beads (red , black , clear , brown  and yellow )and a gold-colored split ring for assembling this shark tooth key chain. I hooked the split ring on a green, large clasp to finish this key ring. The clasp can be pressed open and hooked to belt loops, purse strap rings, etc.
All components of this shark tooth key chain purchased new.
I assembled one shark tooth key ring in this design.
