Never heard of ADL--is that a certification telling you what it is or what it is worth? If it's a valuation, I wouldn't trust that. I've seen a few "labs" put ridiculous values on things and seem to be pulling that stuff out of thin air.

What size are you looking for? You'll definitely have your work cut out for you looking for a fancy color. Good luck

There's basically three ways to get a blue diamond that is not a natural stone:

1. Get a synthetic that has been grown with boron in the diamond crystal. That is basically the same cause of colour in a natural blue, and it will look like a "true" blue diamond. The colouring is permanent, and it is going to be relatively expensive (still a fraction of the cost of a natural blue, but about the same price as a good "colourless" natural diamond). Gemesis and D.Nea manufacture and sell them.

2. Get an irradiated diamond. The colour is likely to be way different from that of a natural blue, but then so will be the cost. The treatment is permanent. Many vendors.

3. Get a coated diamond. Again, colour is likely to be very different from natural. It will cost even less than an irradiated stone, but the coating may be relatively easily ruined/scratched, and recoating will cost a pretty penny.

Out of left field: have you considered a sapphire, iolite or tanzanite?

I've never heard of the ADL certificate. What size, and shape are you looking for in the blue diamond?
