I was looking at some diamonds in a local store and saw a 3/4 ct. Lazare ideal cut (AGS 0) which looked beautiful but is priced considerably higher then similar stones here on pricescope. How much extra does the Lazare name cost. On a side note, how much do retailers mark up their diamonds? This retailer came down a grand when mentioning how much less the prices were on pricescope. Price is still $500-$700 higher then compareables here (non Lazare) after their discount.
