What is an Ideal, Very good and/or good depth for radiant stones?

[trueshine]

Just wondering...

Radiants must be looked at in person to judge its beauty. But number crunching does help eliminate the not so good looking ones.

Depth 60% - 65%
Table 60% - 65%
Crown Height 10% & upwards

If you want more fire, get a stone with a depth closer to 70% and a smaller table. If you want more brilliance, find a stone with a shallower pavillion depth, closer to the 60's.

You can rule out bad stones off the numbers, but you can't rule them in. Two radiants with the exact same numbers can look completely different, because the numbers don't come close to covering all the variables involved.

I would also aim for at least VG or better ratings for the Polish and Symmetry.

It''s hard to say what is "ideal" for radiant stones, they must be seen and compared. However, as a general guideline Chrono''s numbers are great!

I don''t know where Amazon took their chart from,but it looks as if it''s just a crude guide.
