After seeing my M620 dark, my best friend fell in love. He wants to trade his engagement ring for a Monster. It is a .78ct diamond rated flawless, as perfect as a real diamond can get. it is in a setting with diamond surroundings, and the entire ring is appraised at over $5k. Bike for engagement ring, he figures when you get one, you have to get rid of the other.................any takers?
