Help me to compare this Neil Lane setting/stone!

[Tuckins1]

Hello all! My SIL recently asked me to look at this lovely Neil Lane ring that she was thinking about purchasing. I have been "out of the loupe" (so to speak) for a while, and am not up to date on current oval or gold prices. The center stone is .75 ct, H-I, SI1-2, and the setting is in yellow gold (although I can only find a pic of the white gold version.) Can you all help me to find similar settings/ stones to compare quality and price? I did loupe it and it was pretty clean, even at 10x and the cut looked pretty good, although I am not an expert on ovals. Happy hunting!!
