Query: Amazing!

I have only had my engagement ring for a few months now, and I noticed that it was beginning to seem a little less sparkly than when I originally received it. I bought this cleaner and I cannot believe how sparkly it is again!!!! This stuff works like magic and I will continue to use it. Yes, the packaging could be better but I will suck it up because this stuff works!!!
