As diamonds in larger sizes become increasingly rare and valuable, any easily visible and readily understood pricing system has been difficult to establish.[citation needed] Martin Rapaport produces the Rapaport Diamond Report, which lists prices for polished diamonds. The Rapaport Diamond Report is relatively expensive to subscribe to and, as such, is not readily available to consumers and investors. Each week, there are matrices of diamond prices for round brilliant cut diamonds, by colour and clarity within size bands, and also other shapes. The price matrix for brilliant cuts alone exceeds 1,400 entries, and even this is achieved only by grouping some grades together. There are considerable price shifts near the edges of the 

size bands, so a 0.49 carats (98 mg) stone may list at $5,500 per carat = $2,695, while a 0.50 carats (100 mg) stone of similar quality lists at $7,500 per carat = $3,750. This may appear such a large difference as to defy logic, but in reality stones near the top of a size band (or rarer fancy coloured varieties) tend to be uprated slightly. Some of the price jumps are related to marketing and consumer expectations. For example, a buyer expecting a 1 carat (200 mg) diamond solitaire engagement ring may be unprepared to accept a 0.99 carats (198 mg) diamond.
