This elements set in bezels have NO perforations to allow you to play as you wish using them as pendants, bracelet focal elements, large dangles or even a focal element.
They try to resemble ancient, old and worn ethnic pieces. 
If you don't have a drill or a drill bit this small, a hammer and a nail can do the trick! -Just be sure to hammer on a piece of old wood or disposable surface- Don't hit too hard on the nail can get into the wood kind of hard to remove. ;) The back can be just sanded to leave a neat and unable to hurt finish back side. 
Bargain bundle to a cost of $10 for each individual element. 
They measure 65x26mm, 47x21mm, 50x34mm, 31x40mm and 26x24mm.
