Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances with every movement. This 12 x 6 mm center stone rests within a delicate halo of platinum, where tiny pavé diamonds amplify its graceful taper and vintage allure.

Crafted in platinum for enduring strength and a cool, silvery sheen, the setting embraces the marquise in a low-profile halo that balances sparkle with everyday wearability. The band’s smooth comfort fit ensures the ring settles naturally on the finger, while the halo’s subtle elevation adds dimension without catching on fabric.

Each diamond is lab-grown, offering a clarity and brilliance indistinguishable from mined stones, with a fraction of the environmental impact. This ethical choice reflects a quiet commitment to sustainability without compromise.

Ideal for those drawn to refined drama, the marquise shape visually elongates the finger, pairing beautifully with slender hands or as a standout solitaire in a stack. Its low profile and secure setting make it glove-friendly and suited for daily life.

Resizing is available to ensure a precise fit, crafted carefully in our Williamsburg studio to maintain the ring’s balance and integrity.
