Tips on buying a diamond


A diamond broker I talked to recently mentioned an interesting heuristic: he never buys diamonds that are exactly 1 carat, because he figures the person cutting the diamond almost certainly sacrificed some quality in order to bring it up to that magic number. and he never guys diamonds that are .98 or .99 carats either, because he figures the cutter was trying to sacrifice quality for the magic number, and then screwed up besides.
