The Small Chunk Necklace has always been a great seller. It is dramatic, without being obnoxious. It can be adjusted shorter, or even a bit longer, if you want to go to the trouble. This one is about 20 inches long, and the middle silver piece is almost 2 inches long, and about 1 inch across. It is reversible if you are in to that sort of thing. The links are brass fused with bits of silver. Get used to strangers chatting you up when you wear this one. If you want to ask how to clean, you don't, just wear it.
