Carat: 4.28
Color: E
Clarity: I1
Shape: Marquise
Metals:
Platinum
Overall Condition: Very Good
Condition Notes: For those drawn to fine diamonds, this 17.20 x 8.72 x 4.75 mm marquise shaped example resides near the top of the colorless range. Graded E color, it sits just one step below D, the highest designation for absence of bodycolor.
To the unaided eye at a viewing distance beyond approximately 18 inches, the diamond presents as visually clean despite its I1 clarity grade, which is influenced primarily by carbon colored crystal inclusions. Two additional very shallow chips are present along one portion of the pavilion just below the girdle. These are not visible face up and can only be observed under close magnified inspection.
The ring shank is unmarked but has been verified as platinum through XRF analysis and standard metal testing methods.
