The Projector Engagement Ring by Luke Jerram is quite possibly the coolest ring ever. Capable of fitting four pictures on its sides, the ring can then project these photos onto a wall with a light or a candle. The ring was created for Jerram's own wedding, making the piece even more romantic.
I'm loving the look and style of this projector engagement ring, but it's the idea that is its key selling point. As a hopeless romantic at heart, this may be the most adorable thing I have ever come across.
