Cut: Excellent
Color: F
Clarity: SI2
Depth%: 61.3%
Table%: 60%

Whats confusing is that I get .05 carat's a better cut symmetry and polish for less money!?

Can someone explain why this might be? Thanks

I wonder...you think the cheaper si2 has flaws visible to the eye...so while they are the same clarity one has visible flaws to the human eye?

The usual reason for differences in superficially similar stones has to do with the grading. Some of it has to do with the dealers.

What’s your source of the grading information?
Are they being offered by the same dealer? If the dealers are different, is there anything about one that makes their deal preferable to you? (tradeup programs, warranties, better documentation, better reputation, better payment terms, nicer salespeople, etc.)
Have you seen either stone? Has anyone? Who?
What do you know about the cutting of either stone? With the one that’s claimed to be ‘ideal’, who is making that claim and what is their definition of ideal?

Which grading should I go by?...is EGL a good company for knowing the true quality of a diamond?

Also both diamonds were from the same site....as for the fiding if both were rated by EGL I can't find the other stone anymore.

But this
Measurement: 5.79 - 5.84 x 3.63
Carat weight: 0.75
Cut: Ideal
Color: F
Clarity: SI2
Depth%: 62.4%
Table%: 56%
Symmetry: Excellent
Polish: Excellent
Girdle: Medium
Culet: None
Fluorescence: None

Is rated by EGL and is selling for $1924...I have heard EGL is very liberal with their ratings

AGS and GIA have, by a lot, the most consistent grading of the major labs. EGL has a reputation for being, umm, less than reliable. This is the reason that superficially similar stones with EGL paper are generally less expensive than stones with GIA or AGS documentation.

There is more than one company that uses the EGL name and they both use rather peculiar definitions of the term ‘Ideal’. If you’re going to pay a premium for idealness, make sure you understand what they mean.

If the dealer is someone who actually has the stones, they should be able to tell you why one is more expensive than the other. If they are a virtual dealer than you probably won’t be able to get a straight answer without calling in the stones for an inspection.
