Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its tapered points tracing a delicate arc that seems to stretch the hand with quiet elegance. This three-stone semi-set in platinum frames the center stone with two gently curved side gems, creating a subtle narrative of past, present, and future.

Crafted in cool, polished platinum, the mounting offers a low-profile setting that balances presence with everyday wearability. Each prong is meticulously finished to cradle the 9 x 4.5 mm marquise securely while allowing maximum light to animate the stone’s signature brilliance. The band’s smooth comfort fit ensures it rests naturally, whether worn solo or stacked alongside a wedding band.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, which provide exceptional clarity and sparkle with a smaller environmental footprint.

This ring suits those who appreciate refined drama and a graceful elongation of the finger, ideal for hands that welcome a slender, architectural shape. Its moderate profile makes it glove-friendly and easy to wear daily without catching.

Should you wish to adjust the fit, resizing is straightforward and handled in-studio with care.
