Shallow Crown?


Recommended Posts

Where did you get the notion/ that a 33 degree crown is shallow? A Crown under 30 degrees is considered shallow and in many instances is accompanied with a razor thin girdle which is susceptible to chipping and fracturing. Medium girdle is fine.


The specs on this diamond are very good and it should be a face up sparkler.

...the answer is: star length. The tables on the Octonus website refer to diamonds with a 55% star, but your stone's star facets are shorter, at 45%.


If you input ALL the parameters in GIA's own cut estimator here: https://www.gia.edu/facetware (it requires registration, but it's free to use) you'll see that the cut grade comes up as "Excellent".
