Loop Necklace

I recently purchased this loop necklace at the local Vinnies store alone with a few other items. It's 46 inches long & has as I beleive to be grey cultured pearls with balls of glass as under a black light the balls show a light mauve in colour, the pearls turn green. This item did not cost a arm or a leg as the lot of about 10 items come to under $10.00. The balls has a tube down the centre that conect them to the chain. It also has no link to undo to put around the neck. I hope you enjoy it as much as I do. I will try & get a more better colour background to show to it's best advantage as this picture was taken inbetween the rain & really wanted some new items to display. Would love to know if anyone could tell me if is of a know artist or just someones hobby. There is no markings that I can determine. I have tried this 3 times I wonder if second picture will stay this time. I believe it to be of the Art Deco style also classed as Iv'e seen it called two other names which are just not coming to mind at the moment.
