I’m in the process of selecting a diamond which will be placed on a 4 prong platinum pendent. I’m deciding between a 1 ct stone vs. a lower quality 1.2ct stone – I list the 4Cs and proportions at the bottom of the post. In general the larger stone is lower in color and clarity, and the GIA certificate mentions that clouds and pinpoints are not shown (the 1 carat only says pinpoints are shown). Also, based on the cut estimator on this site, the smaller stone may be slightly better cut, though they fall in the same GIA/AGS cut grades.
The price of the 1 ct is $6000 and the 1.2 ct is $6800. Thoughts on whether this trade off for the larger carat is worth it, given that the diamond will be worn on a 4 prong platinum pendant?
Pasting below details of each from their GIA certificates, though happy to post more details from it if I’m missing anything important:
Crown Angle: 32.5
Pavilion angle: 41.6
Comments: Pinpoints are not shown.
Crown Angle: 36
Pavilion angle: 41

Here’s the 1.01 G SI1 (2223035761). It was $5880 on Feb 21.
Here’s the 1.20 H SI2 (2215534015). It was $6580 on Feb 21.
Of the two, I’d prefer the 1.01 G SI1. I think it’s overall a nicer diamond.
The Ritani 1.2ct link isn’t working for me. If it said $500, that must have been a mistake. Your prices are fair.
