Love how it looked
Purchased in 12/2024. Wore it every day without taking it off. Its coating has worn off on most of the bracelet now but I still consider it got my "moneys" worth from it. Took it off 4/25/26

I wish I could still wear it.
I liked the look and style of this bracelet. I had many compliments when I wore it, but about one month later the base of the clasp started to split open. What a waste, it is a beautiful bracelet.
