Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo ring foundation in 18K white gold awaits your choice of an 8 x 4 mm marquise center, designed to amplify the stone’s dramatic sparkle with a delicate frame of smaller diamonds.
Handcrafted in our Williamsburg studio, the band is polished to a satin-smooth finish that rests lightly against the skin. The halo setting balances brilliance with wearability, offering a low-profile design that slips comfortably beneath gloves or alongside stackable bands.
Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity with conscientious sourcing. The cool white gold complements the marquise’s vintage-inspired shape, elongating the finger while maintaining a modern sensibility.
Ideal for those who appreciate artisan craftsmanship and a ring that feels as natural in daily life as it does in moments of celebration. Resizing is available to ensure a precise fit, with lead times tailored to your custom design journey.
