The company name is Universal Diamonds with an 's' at the end (my mistake when creating the contest), sorry.
Also, I'd like to see the logo with 'Universal Diamonds' written in a few font variations. And, I want the symbol to look a little more sleek with the way the "UD" overlaps the diamond. Since the logo comes to a point at the bottom, perhaps the thickness of the bottom right part of the "D" can gradually get skinner as you reach the bottom point. Maybe similar to the way the top left part of the "U" looks like it gets skinnier until it blends in with the top line of the diamond.
