Mixed Shapes. Matched Elegance.
This 1.20-carat half eternity ring features a striking combination of 6 marquise-cut and 7 round-cut lab-grown diamonds, creating a dynamic, vintage-inspired look with a modern edge. Alternating shapes bring visual rhythm and brilliance, making this band a standout for stacking, gifting, or meaningful milestones.

Crafted in your choice of Yellow, White, or Rose Gold (10K, 14K, or 18K), the bold lines of the princess-cut center stone are softened by round diamond accents that deliver elegant sparkle with every turn.

Each diamond is IGI certified, sustainably lab-grown via the CVD method, and selected for its premium E–F color and VVS–VS clarity.


Note: Diamond weight and gold weight may vary by 3–5% due to the handcrafted nature of the piece. Every piece is made to perfection with unmatched attention to detail.
