Why We Love It
Such a stunning old mine cut diamond, with a touch of warmth that still faces up beautifully white. One of its most captivating features is the coveted kozibe effect, where the culet reflects through the facets to create a mesmerizing, extra glittery look. The stone is well laid out, so it faces up nicely for its carat weight. This stone would be equally beautiful set in a ring or worn as a pendant, and we love it in yellow gold or platinum!
Here are some ways to make this stone shine: Lulu Pendant, Lorena, or Melissa.
The dimensions of the stone are 8.97 x 8.81 x 5.26 mm.
