Low crown angle- advice?

[Green with Envy]

This RB seems to have lower crown angle than other AGSO. How will this affect the apperance of the diamond?

It scores 0.8 Ex on the HCA with all EX. here is pic...

Will look bright and will not show dirt as much as a deeper stone. Read the HCA "warning" for more info.
Slightly higher risk of chipping in an exposed ring setting - perfect for pendants and earrings as they gather less light from the floor than Tolkowsky and deeper stones

Got it- good for pendant. Will it also have less fire, but look brighter? If is has lower crown angle.... will that effect darkness that sometimes the H&A''s have under table in certain lighting?

Hi GWE & GH.

I'd like to mention that a 33.9 degree crown angle is not what we would ever call low in terms of 'shallow' or less druable.

The GIA used to flag diamonds at 30 degrees and below. We, along with many of our reputable peers, exercise caution before that - always looking at the girdle too - but 33.9 is in a safe zone.

Official GIA definitions:

Slightly shallow crown = at or near 31.5
Moderately shallow crown = at or near 26.5
Shallow crown = at or near 22.0
Very shallow crown = at or near 20.0
Extremely shallow crown
Some discussion before (shallow crown thin girdle thread) for any interested.
