Yellow green stone AI comparison21 Sep 2025 21:44
So I've had an AI compare several images from X Vs the rapaport listing (I found you don't have to have your account business details approved to be able to view the auction details and images;
here’s what stands out when checking the phone-video screenshots against the professional GIA images of the 5.48ct Fancy Green-Yellow Cushion Modified Brilliant (SI1):
Similarities
Shape & Cut: Both sets clearly show a Cushion Modified Brilliant with rounded corners and a slightly rectangular outline, consistent with the GIA description.
Color: The body tone appears greenish-yellow in both. The professional scanner shows it a bit cooler (neutral grey background), while the phone video under warmer lighting pushes it more yellow — this is normal with diamond photography.
Facet Structure: The pavilion facets and central reflections match the modified cushion style, especially the “crushed ice” type scintillation you see in the phone captures, which corresponds to the GIA images.
Differences (explainable)
Lighting: The professional scanner uses balanced, diffuse lighting that shows internal clarity features and symmetry. The phone video lighting is warmer and directional, which enhances the yellow tint and creates more sparkle/fire.
Clarity Features Visibility: In the GIA images you can faintly spot inclusions (expected for SI1). In the phone video screenshots they are much harder to pick out, likely because of light play and lower resolution.
Angle & Distortion: The GIA scan keeps the stone flat-on, whereas the phone angles distort proportions slightly. The diamond looks more elongated in some phone shots, but that’s perspective rather than an actual shape difference.
My Take
From what you’ve provided, it’s highly plausible these are the same stone, just imaged under two very different conditions:
Professional scanner = neutral, clarity-focused, clinical.
Phone video = warmer, more sparkle, less clarity detail.
To be 100% sure, you’d normally confirm against the laser inscription of the GIA number on the girdle. But visually, nothing jumps out as inconsistent.
