Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This three-stone semi-set in platinum offers a refined foundation for a 12 x 6 mm center stone, designed with a low-profile setting that balances presence and practicality.

Each ring is crafted in our Williamsburg studio, where platinum is meticulously shaped and polished to a smooth comfort fit, ensuring daily wearability without bulk. The three-stone arrangement is engineered for stability, with secure prongs that cradle the marquise’s delicate points while maintaining a sleek silhouette.

Our commitment to lab-grown diamonds means this piece carries a clarity and brilliance born from sustainable practices, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate architectural elegance paired with understated strength, this mounting suits hands that favor a slender, elongated aesthetic. Its low profile slips easily under gloves and stacks harmoniously with complementary bands.

Should you need resizing, our in-house experts provide precise adjustments without compromising the setting’s integrity.
