Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set ring in 14K yellow gold offers a modern-minimalist framework, where clean lines and structural clarity take center stage.

Crafted in Williamsburg, the band’s smooth finish and subtle taper cradle an 8 x 4 mm marquise center stone, ready to be chosen and set alongside two complementary side stones. The low-profile design ensures everyday comfort, while the secure prong setting highlights the diamond’s dramatic shape without excess metal.

Each lab-grown diamond reflects a commitment to sustainable luxury, reducing environmental impact without compromising brilliance or clarity. The warm glow of yellow gold pairs naturally with the marquise’s elongated form, flattering slender fingers and balancing bold geometry with graceful wearability.

Ideal for those who appreciate architectural elegance and understated confidence, this ring layers effortlessly with other bands or stands alone as a statement of refined taste. Its semi-set nature allows you to select a center stone that resonates personally, making the design uniquely yours.

Resizing is straightforward, handled with care in our Brooklyn studio to maintain the ring’s precise proportions and comfort fit. Typical lead times accommodate thoughtful customization without rush.
