This item is one of one

Please note: the price is for the diamond only, and any setting would be an additional charge. We are happy to create a setting for you- whether it is an AB Signature Design or something else you're dreaming of. Get in touch, and we can help bring your vision to life!
Why We Love It
This deeply rich yellow diamond feels like pure sunshine. It has that quintessential Old Mine cushion shape that we know and love. One of its most captivating features is the coveted kozibe effect, where the culet reflects beautifully through the facets, creating a mesmerizing, extra glittery look.
It’s an incredibly charming and soulful stone. While it would be perfectly complemented by a warm gold setting that enhances its color, it could also take on a striking, Art Deco edge in platinum for a more unexpected contrast.
Here are some ways to make this stone shine: Marielle, Hera, or My Heart to Give.
The dimensions of the stone are 9.87 x 9.18 x 6.00 mm.
