To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Good product - does what t says on the tin - brought back the shine to my wife’s engagement ring - however my only slight criticism would be it does not last very long but this could also be my wife’s fault as she has to keep washing her hands for work.
I feel like it didn’t make a stunning difference. I cleaned three different rings that I wear daily with very different styles of setting to test it. The one I wanted to clean the most didn’t have very much of a change. I’ve included before and after pictures of that one. The before pic shows a dull-looking ring. The after shows a cleaner ring, but not as sparkly or shiny as I had expected. Even after three thorough passes with the pen. I found that the pen worked best on my simplest ring with one diamond set right flush with the band. Probably wouldn’t purchase again.
