D&E always closed the linkages of their bracelet in the front of the bracelet and covered the seam with rhinestone(s). The non D&E bracelet close in the back of the bracelet.
So if you ever see a 5 link with the linkage closing in the back of the bracelet, it is NOT D&E.
Also if the linkage is not closed and you see a rivet, that is also not D&E
