Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a 5 x 3 mm marquise diamond, its tapered points drawing the eye along the finger with quiet elegance. This semi-set engagement ring foundation in 18K rose gold offers a delicate warmth that complements the stone’s dramatic shape without overpowering it.

Crafted with a low-profile setting, the mounting ensures the ring sits close to the hand, minimizing snagging and enhancing comfort for everyday wear. The rose gold band is smoothly finished with a subtle curve that balances durability and grace, ready to receive your chosen center stone alongside finely detailed accent settings.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, reducing environmental impact while maintaining exceptional clarity and brilliance. The marquise shape’s elongated form naturally elongates the finger, ideal for those seeking a refined yet distinctive silhouette.

Designed for daily life, this mounting fits comfortably beneath gloves and stacks seamlessly with other bands, making it a versatile choice for a modern engagement ring. Resizing is available to ensure a precise fit, crafted with care in our Williamsburg studio.
