Condition Report*:
Diamonds:
Avg Color: G-H-I
Avg Clarity: VS
Shape(s): Marquise, Baguette, Single, and Full-Cut
Count: 100+
Metals:
Platinum
Overall Condition: Good
Condition Notes: Radiating outward in sharp, symmetrical lines, this Art Deco–style piece combines architectural geometry with refined gemstone work. At its center, three marquise-cut diamonds are arranged in a pointed cluster, evoking a stylized floral or leaf motif. These stones are well-faceted and clean in clarity, ranging from approximately 7.50 x 3.50 x 1.65 mm to 8.40 x 3.50 x 2.05 mm. Below them, a rectangular baguette-cut diamond measuring approximately 6.00 x 4.50 x 2.95 mm anchors the composition; this stone bears a chip to one corner, now partially concealed by surrounding metal.
The remainder of the diamonds exhibit high color and clarity, with minimal visible wear under magnification. Evidence suggests the brooch may have originally served a different function, with the current pinstem added later in its life.
