Handcrafted (by me) solid sterling chain in your choice of length (15-18 inches).
All links are soldered closed making for a very strong chain. Large sterling lobster claw clasp worn in front enables the 4 inch piece of smooth black onyx pendant to be fastened onto the chain. I have put a handcrafted sterling cap and black faceted hematite bead on top to give a nice finished look. 
Wear the chain alone or with a pendant of your own.
