I''ve seen a couple pink diamond bands by Leon Mege. He makes gorgeous micropave rings. I have a RB with a pink halo, if you want to check out his work. Not sure about the price but I know that pink diamonds are more expensive when they are more saturated (ie., more pink). Definitely worth calling him and finding out his price. www.artofplatinum.com
I actually emailed Leon for a quote about 2 weeks ago for a pink diamond eternity band. He said that the pale, lighter pink band will be $3000 and the brighter vivid pink band would be $6000.
De Beers makes a pink diamond band for $3450 I think, it''s 1.55 mm thick and .40 carats. Google "de beers pink match band" and you can see it.
Martin Katz makes a pink diamond band also but it''s very expensive: $6500 I believe.
