The Round is perhaps the most popular of the shapes available. This is a good indicator of the diamond price for the size and quality of most diamond rounds. Some shapes, such as the Princess and the more unusual cuts might be slightly lesser in price.
Each set has a table for each weight of .5 to .69ct, .70 to .89ct, .90 to .99ct, 1.00ct, 1.5ct, 2.00ct, 3.00ct, 4.00ct and 5ct.
How much you pay for a particular diamond can also vary from dealer to dealer. These are just the approaximate prices to give you some idea of the diamond prices you would expect to pay. These diamond prices given purely for information and guidence only. The actual price you pay is likely to to be very different and could be anywhere up to 20 percent either side of the values given.
You might notice some inconsistances in each matrix. For example, you will note that the difference between a 1ct G color VS2 clarity diamond and a 1ct H color VS2 clarity diamond is $1000 dollars, yet between the same G VS2 and a 1 ct F VS2 is only $500. Much of this is to do with rarity at the time opf pricing of these various stones. So using a professional diamond dealer can help here as there can be many ways to spot a good deal taking advantage of these inconsistances. It might require some research and due diligence but is well worth it if it can save you a fre thousand dollars for what could be, very little difference in the actual diamonds.
