This presentation is delivered for Barcamp 7 which is held on 10 Sep 2011 in Block 71, Mediapolis Singapore. It's a fun presentation where I present the economics, myths and science in searching for an engagement diamond ring for my fiancee. For example, I will also cover the 4Cs of diamonds (Clarity Cut, Color and Carat) in a layman manner and how to purchase the ring. The story helped me realized that each man's search for the one ring is filled with intrigue and interest.
