Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender, dramatic beam that dances with every movement. This halo setting frames the 12 x 6 mm stone with a precise circle of platinum, amplifying its architectural silhouette without excess.

Crafted in polished platinum, the band offers a sleek, low-profile design that rests comfortably against the finger, ideal for daily wear. The halo’s delicate pavé setting is meticulously finished by hand, ensuring each tiny diamond is securely nestled to enhance brilliance while maintaining a smooth touch.

Our lab-grown marquise diamond embodies clarity and ethical responsibility, created with minimal environmental impact and traceable origins.

The ring’s elongated shape visually lengthens the finger, suited for those who appreciate modern geometry and confident structure. Its low profile and comfort fit make it an excellent choice for stacking or wearing alongside a wedding band without bulk.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
