I handcrafted this incredibly adorable crab necklace using a genuine carnelian stone for the main crab body (this stone is faceted) and a pearl that the crab is holding on too and attached to the chain. The metal I used is solid copper wire and beads that has been oxidized and polished to give the piece more depth and dimension.
 
Necklace dimensions: from claw to leg the crab is 1.05 inch long x 0.98 wide (right)
 
*Comes on a non-removable copper chain to match
