Carat size vs. measurements

[sparkles31]

Which determines how large a radiant actually looks from the top? Could you actually go by just measurements instead of carat size?

Surface size, not weight - stones of the same weight can look quite different in size and the larger the weight, the more obvious this is.

IMO, yes, sure.

Since you were looking for radiants 17-2cts...

Here's an example of what I am trying to say:


weight:2.03 - size: 7.48x6.50x4.74

weight: 1.70 -size: 7.56x6.60x4.23

Both have reasonable numbers (neither is shallow well above 65%) and same grades (GIA) G-SI1, and about the same size (2cts a tiny hair smaller?). The weight makes for a 6k price difference... The tutorial about cut quality for the original radiants (at radiantcut.com) is the only place where I saw any mention about this weight versus size thing. On a database, it is quite obvious though.

I would not second guess the spread (whether a stone is large or small for its weight) based on depth & table percentages because for radiants the relation is not simple (more depth doesn't always mean a smaller stone). Since the diameter is given - the point is moot, hopefully.

For an example, look at my ring. It''s a cushion and it''s only 1.08 but EVERYONE thinks it looks a lot bigger than that, b/c apparently the spread is more like a 1.5. But it''s still cut really well and sparkles like crazy, so you would never guess that it''s cut shallow! So I''m all for choosing based on mm dimensions!

Thanks for that
