Question about RCDC diamonds and table/depth

[Winnme1]

I have been reading up on radiants for quite some time. I was hoping that Stan or someone else who has knowledge of radiants could please answer the following question. From my research on here, it has said that the table should be lower up to 5% as compared to the depth. Whenever I looked at the selection of rcdc diamonds online, for every diamond the table is always higher than the adjusted depth. I am confused about this and would please like someone to tell me why this is so. Also awhile back one of the jewelers that had some rcdc diamonds for me to look at told me that becuase it is an rcdc I can have an "I" color and it will face up to an H. I know that for genarics you should not go below a "G" but what is the case with RCDC diamonds. Can''t wait to hear some answers. Thank you!

Hi Meg,

I understand your confusion. There is a lot of inconsistent information out there concerning cut quality of radiant cuts, and it can be hard to know who or what to believe. The myth that the table should be smaller than the depth is a good example. If you were buying a generic radiant sight unseen, it might be wise to choose one with the table smaller than the depth, because this would make it a bit less likely that the crown (top) of the diamond was too flat (a common problem). But if the crown is not too flat, then the size of the table relative to the depth is completely irrelevent. And it is quite possible for a radiant with a table% smaller than the depth to still have a crown which is unacceptably flat. Both depth and table should be within the appropriate ranges, but it makes absolutely no difference what they are relative to each other.

With respect to Original Radiant Cuts, our "adjusted depth percentage" will be significantly lower than conventional depth percentage for rectangular diamonds. If you compare the table sizes of our diamonds to the conventional depth percentage, you will find that our table percentages may be larger or smaller than the depth. As long as the table is within the appropriate range, which we consider to be 55% - 69%, the "best" choice is a matter of personal taste. Depth and table %''s are just two factors among many, and it is important not to lose sight of the forest for the trees. You should look at the overall appearance of any diamond that you are considering and choose the one you think is most beautiful.
