Bought this for my daughter-in-law and she wore it every day without taking it off for nearly a year (I had purchased a sterling silver choker for it.) Unfortunately, the post recently came out of the pendant, and she lost it. I would suggest a dab of super glue as a precautionary act if you purchase this. Before Purchasing, a person should also know the definition of dichroic glass. Dichroic glass contains multiple, micro-layers of metal oxides which give the glass dichroic optical properties. It was first developed by NASA! All in all, because it looked so pretty on my daughter-in-law and because she loved it, I have to rate it higher than most have.
