the chains are set into a clear vinyl epoxy band, which is hidden behind them and just makes the whole thing more sturdy and less scratchy on your neck.  

it closes in back with a lobster claw clasp and chain 

new in baggie.  

its very sparkly, with a rainbow, iridescent sheen. 

My camera just was not able to catch the colors properly 

(that last, fuzzy, out-of-focus picture did a pretty decent job...hopefully it will give you a better idea.)  

necklace adjusts between 12 - 15" around, 

so best for necks from about 11 to 14.25" around. 

nearly 1.5" wide

I have the same necklace in other colors, and other widths, available in my ebay store.
