Curious about the specs

[wtd]

I am wondering about the specs of this diamond and was wondering if anyone can comment? It came up as 2.5 on the HCA. The vendor doesn't have any ASET or IS images.

Depth: 60.9%
Table: 58%
Crown Angle: 33.5°
Crown Height: 14.0%
Pavilion Angle: 41.2°
Pavilion Depth: 44.0%
Star length: 50%
Lower Half: 75%
Girdle: Thin to Medium, Faceted
Culet: None

Numbers are fine. Any other info/pics, and link to report?

It's an online vendor that doesn't have any pictures. They said they can take pictures/send link, I'm just waiting on those.

In the meantime, how about this one instead? It got scored 1.3 on the HCA, but the crown angle is 28. Is that ok?

Depth: 57.5%
Table: 58%
Crown Angle: 28.0°
Crown Height: 11.0%
Pavilion Angle: 41.4°
Pavilion Depth: 43.5%
Star length: 55%
Lower Half: 85%
Girdle: Thin to Medium
Culet: Small

28%? I never heard that before... Could it be a typo?

Numbers work out... OP, run. Fast. There isn't a planet on which a 28deg crown plus a thin girdle is a good idea - and that's ignoring all the other issues.

Ok, what about this one? It comes with both a GIA and AGS certificate. The numbers vary slightly (which makes sense), but when I plugged in the GIA numbers in the HCA calculator, it gave me 2.4. AGS numbers gave me 1.8. Should I care about the differences? I've noticed some stones have 75% lower half vs others have 80%. Is there a major difference btw the two in terms of how they will look?

GIA cert:
Depth: 62.6%
Table: 55%
Crown Angle: 35.0°
Crown Height: 16.0%
Pavilion Angle: 41.0°
Pavilion Depth: 43.5%
Star length: 50%
Lower Half: 75%
Girdle: Medium, Faceted
Culet: None

AGS cert:
Depth: 62.6%
Table: 54.5%
Crown Angle: 34.7°
Crown Height: 16.0%
Pavilion Angle: 40.9°
Pavilion Depth: 43.3%
Girdle: Medium - Sl.Thick

GIA rounds crown to nearest 0.5d and pav up to nearest 0.2d so the reports are in agreement. Numbers are fine - can't tell you anything beyond that without more info/pics though.
