Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring features a 9 x 4.5 mm marquise center, its pointed ends drawing the eye along the finger’s natural line.

Crafted from warm 10K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear. The three-stone setting balances presence with subtlety, allowing side stones to frame the center without overwhelming it. Each prong is hand-finished to secure the stone low against the finger, creating a refined, low-profile silhouette that slips easily beneath gloves or sleeves.

Our diamonds are lab-grown, offering clarity and brilliance with a lighter environmental footprint. This ring’s ethical origin complements its artisan construction, reflecting a modern approach to fine jewelry.

Ideal for those who appreciate architectural elegance with a romantic edge, the marquise shape elongates the finger while the three-stone design adds narrative depth—symbolizing past, present, and future. The rose gold’s gentle hue enhances warm skin tones and pairs beautifully with stackable bands or a wedding ring.

Should you need resizing, our Brooklyn studio provides precise adjustments to ensure a comfortable, lasting fit. Typical lead times accommodate careful handcrafting and quality inspection.
