This presentation is delivered for Barcamp Singapore 7 which is held on 10 Sep 2011 in Block 71, Mediapolis Singapore. It’s a presentation meant for me to share. In this talk, 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 some tips on how to purchase the ring. The story helped me realized that each man’s search for the one ring is unique and filled with intrigue and interest.
