Read this article on color-enhanced and clarity-enhanced diamonds:

http://en.wikipedia..../Diamond_enhancement

Specifically, it says, "The CIBJO and government agencies such as the United States Federal Trade Commission explicitly require the disclosure of most diamond treatments at the time of sale."

HI All!
Welcome to you Red-Hatter- thanks for posting!

I'm a bit skeptical of Wikipedia- I'm sure there's a lot of great info there- although some specifics I've seen regarding diamonds were not accurate.

There's absolutely NO question that there's so many sellers offering treated stones with less than full disclosure.

In terms of the "retail" aspect: Since natural colored diamonds are so rare- and it's a very specialized part of the diamond business, few "normal" jewelers carry any selection at all.
Plus, even if they have one or two pieces- the information you might get is questionable- for the lack of experience in this specialized field.

Of course you can shop for pinks at stores like Tiffany, Cartier- and the "big boys" as an alternative.
Of course there you'll find very pricey options.

Even markets such as St Thomas, and St Maarten- with which we have tremendous personal experience,  are not necessarily a great option.
In many ways these markets are similar to 47th Street in New York.
There's a few good sellers mixed among many that are questonable.
Plus, the intense competition creates some intimidating sales tactics.

Basically, if one is searching for a pure pink diamond- or even a lovely pink with brown - you're going to need a strong pocketbook.
