This 1.160 carat, G-color, VS-2 clarity, round brilliant ideal cut diamond from James Allen has an overall cut grade of AGS Ideal-0 as graded on the Platinum Light Performance grading platform of the American Gem Society Laboratory (AGSL) and measures 6.71 – 6.76 x 4.16 mm with a total depth of 61.7% and a table diameter of 56% with a crown angle of 34.7 degrees, which is offset by a pavilion angle of 40.9 degrees, with a thin to slightly thick, faceted girdle and a pointed culet. The primary inclusions are small diamond crystals, clouds of pinpoint size diamond crystals and a few tiny feathers, nothing that I’m concerned about. It’s currently selling for $10,180.00 and should exhibit phenomenal light return, it certainly looks great in the spinning clarity photograph, it’s kicking off lots of sparkle!
This diamond is not part of the James Allen True Hearts collection, so I can’t tell you anything about the optical symmetry of the diamond, but I imagine that we could get them to take a photograph of the diamond through a Hearts & Arrows viewer to determine the extent of optical symmetry. This is an important thing to consider because while the proportions of a diamond dictate the volume of light return, it is the optical symmetry of the facets which determine the size and number of virtual facets, and this has a direct affect upon the visual performance or “sparkle factor” of the diamond, in terms of whether it is exhibiting more reflected white light (brilliance) or dispersion (fire, or colored flashes of light) along with the overall degree of scintillation.
This 1.225 carat, G-color, VS-2 clarity, True Hearts Diamond from James Allen is graded by the AGSL with an overall cut grade of AGS Ideal-0 on the Platinum Light Performance grading platform. The diamond measures 6.88 – 6.92 x 4.26 mm with a total depth of 61.7% and a table diameter of 53.9% with a crown angle of 34.4 degrees which is offset by a pavilion angle of 40.9 degrees and a thin to medium, faceted girdle with a pointed culet. All right, Pro’s and Con’s… The proportions are great and it looks quite lively in the spinning clarity photograph… the only inclusion which gives me pause is the feather indicated in the 4 o’clock region of the lower plotting diagram and the 8 o’clock region of the upper plotting diagram.[separator]
This diamond is currently selling for $11,940.00 and the hearts and arrows pattern of this diamond looks great, so I am confident that the optical symmetry of the diamond is excellent. It should exhibit a virtual balance of brilliance and dispersion with a high degree of scintillation. I’d ask for a clarity photograph of the feather within this diamond from a top down and side profile (at like 30x – 40x magnification) to make a final judgment call about the feather.
