Ok guys. This was the first wedding gift I received after our engagement (thanks, Leah!), and it’s seriously THE BEST cleaner for your diamonds. It had been sitting on my desk for a few weeks and one afternoon I looked down at my ring and couldn’t believe how dirty it was getting; granted I hadn’t cleaned it since the proposal almost 2 months prior. I grabbed the “pen” and once I started cleaning it I literally gasped at how sparkly it made the diamond! It looked like the day I received it, if not cleaner! It’s just a brush that has a soap solution inside and you brush on diamonds or gemstones then rinse with water. It takes no time at all! This would be the perfect gift for any bride-to-be or anyone with jewelry. You can get 3 for under $15 on Amazon!
