Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in warm 10K rose gold frames the center stone with a delicate circle of pavé, enhancing the marquise’s signature drama without overwhelming its modern-minimal clarity.

Handcrafted in Williamsburg, the band’s smooth, low-profile shank balances presence with everyday wearability, offering a comfort fit that slips easily beneath gloves or alongside stackable bands. Each prong is meticulously finished to secure your chosen stone while maintaining a refined architectural line.

Crafted from lab-grown diamonds, this design reflects a commitment to ethical jewelry—minimizing environmental impact without sacrificing brilliance or clarity.

Ideal for those who appreciate structured elegance and subtle statement, the marquise shape elongates the finger, while the halo setting adds a whisper of vintage allure reinterpreted through a contemporary lens.
