Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident, architectural edge. This three-stone semi-set ring in 18K white gold offers a sleek, modern-minimal frame that balances clarity and structure without excess.

Each band is meticulously crafted in Williamsburg, Brooklyn, with a low-profile setting that sits comfortably for everyday wear. The 9 x 4.5 mm marquise center stone is designed to pair seamlessly with side stones of your choice, allowing a personalized expression within a refined, geometric composition. The smooth finish and precise prong work ensure durability and a polished feel against the skin.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, chosen for their exceptional clarity and sustainable origins.

This ring suits those who appreciate architectural elegance and desire a piece that layers well with other bands or stands alone with quiet confidence. Its streamlined silhouette is glove-friendly and ideal for hands that favor elongated shapes.

Should you need resizing, our Brooklyn studio offers expert adjustments to maintain the ring’s integrity and comfort.
