Property of a Prominent Dallas, Texas Estate
Condition Report*:
Diamonds:
Avg Color: G-H-I
Avg Clarity: SI
Shape(s): Round Brilliant and Full-Cut
Certified Diamonds:
Stone: 1
Lab: GIA
Certification #: 5319735
Carat: 12.55
Color: G
Clarity: SI1
Shape: Marquise
Metals:
Platinum
Overall Condition: Good
Condition Notes: This giant marquise-cut diamond measures 23.27 x 12.46 x 7.87 mm, showcasing an elongated profile and broad spread that give it exceptional finger presence. Graded G color, the stone falls at the top of the near-colorless range, offering a bright, icy white appearance with crisp light performance under both natural and artificial lighting.
Though graded SI1, the inclusions are barely visible to the naked eye, maintaining the stone’s overall clarity and brilliance. It is flanked by tapered baguette diamonds that angle inward to draw attention toward the marquise. One baguette shows a chip, but the primary visual focus remains on the commanding center stone. One tip of the marquise is fully visible and undamaged; the other is more concealed within its prong setting but appears intact upon inspection.
