Hi Neil and David,
Thanks for the reply. I made a mistake on my earlier post.. i meant to say 25 pieces of 0.02 - 0.03 each. I'm considering having my wedding band custom made and is toying with the idea of using natural faint blue diamonds (just a light hint of blue). The design we have in mind is a small row of channel set diamonds ala eternity style set across a platinum band.
Just scouting for some idea bout the cost and if its really practical to do so. I know natural blue diamonds are hard to come by.. but at the small carat weights i have in mind, i was hoping it'd be easier

. Plus I've read the ones which are vivid coloured are the more costly ones, compared to faint coulours.
