Collet Set 4.39ct Antique Diamond in Two Tone Setting The Allie 4.39 ring is an AB original design made right here in NYC. The ring centers a GIA-certified 4.39-carat old Euro / old mine cut hybrid diamond of K color, SI1 clarity. The stone is collet set in a platinum and 18kt yellow gold setting. The ring is currently size 6 and can be resized! Why We Love It One of our favorite antique stones we've encountered. It has this distinctly antique look with an adorable large culet and a puffy, cloud-like crown. We set her in our very antique-inspired Allie setting for that Georgian feel. The dimensions of the center stone are 10.10 - 10.81 x 5.67 mm.Click here to view the GIA report on the diamond.
