Radiant Table

[ksivad]

I just wanted to follow up with my previous question about table size. I realize that table size does not necessarily dictate the size of the stone. Both stones I am looking at have basically the same measurements. My major concern is - will there be a difference in brilliance/fire between a radiant stone with a 63% table and one with a 69% table (all else being the same)? Thanks again for all the helpful advice.

With a larger table like that you will probably get less fire and possible less scintillation, but it's not as pat with fancy shapes as with RBs.

Crown height has a lot to do with it. The higher the crown (which usually goes along with a smaller table), the longer the "prisms" created by the bezel facets are. Longer prisms create more "fire" (dispersed colored light return, the rainbow flashes).

As far as brilliance goes, if everything else is "equal" between the two stones, you probably wouldn't notice much difference in brilliance (white light return) between the two.

Crown height would definitely be helpful in making a decision. That, and a visual inspection. A visual inspection is the final word.

I would agree with Richard
