The diamond is not certified and was cut in russia not belgium.
There is not cert.
crown height 7.8 (from sarin machine)
depth 73 (from sarin machine)
table 75 (from sarin machine)
Color F
VS2 (crystal is halfway from center of table to edge about 11 o'clock in the diamond)
0.57
4.52 x 4.6 x3.3
Polish/Sym VG

The diamond has more dark areas looking down through the table. The other .51 diamond looks slightly better (has little dark area looking down). They both sparkle about the same. Neither has flouresence. Light return looks slightly better on the .51

Asking 1750 for the .57
What would you say about the quality of the two diamonds. Even though the sym is VG on the .57 it looks more like G

Which diamond is better? Thoughts? Questions?
