Special Cut Diamond Shapes
Facet Structure - Square H&A
As with rounds the facet structure is very similar since the cutters were attempting to mimic the most brilliant rounds. From the top or crown view you have your 8 stars (in purple), 8 bezels (in red), 16 upper girdle facets (in teal) and 1 table (pink). On the pavilion, 8 pavilion mains (blue) and 16 lower girdles (yellow). Each Square H&A is lab graded by non other than GIA. No diamond we have witnessed gets lower than "Very Good/Very Good", however most get Excellent/Excellent with regards to the polish & symmetry grades. Neither the polish or the symmetry grade however affect the optics of these diamonds which is more directly affected by the proportions & optical symmetry. The proportions on the Ideal Squares all fall within the current AGS definitions of "Ideal Cut" regarding crown angles, pavilion angles and table size.
