A bold and luxurious statement, this engagement ring features an 8mm cushion-cut Black Onyx, the December birthstone cut in a checkerboard pattern for enhanced depth and brilliance. Its dramatic beauty is framed by a halo of sparkling white diamonds, creating a perfect balance of contrast, sophistication, and radiance.

Crafted in fine 10K white gold, the band provides both timeless elegance and lasting durability. The clean lines and high-polish finish highlight the gemstone’s striking character while allowing the diamonds to reflect maximum light from every angle.
