Here's a necklace I purchased on Ebay not so long ago. I also got matching earrings with it. I probably wouldn't wear them together in real life like I did for these photos. If you want one like this, search for 'black bead necklace' on Ebay and you should find it. I got this jewellery set for $1.97 (buy it now, free shipping).
Thanks for looking and commenting!
