Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set engagement ring foundation in warm 10K rose gold invites your choice of a 12 x 6 mm center stone, framed by delicate accent settings that whisper artisan precision.
Each band is hand-shaped in our Williamsburg studio, the rose gold softly brushed and polished to a subtle glow that complements the diamond’s fiery facets. The low-profile mounting ensures a comfortable fit beneath daily gloves or alongside stackable bands, designed for ease and elegance in equal measure.
Crafted with lab-grown clarity, this piece carries an ethical promise—minimizing environmental impact without compromising brilliance or durability. The marquise cut’s elongated form flatters a variety of hand shapes, offering a distinctive yet wearable statement.
Should you need resizing, our in-house jewelers provide careful adjustments to maintain the ring’s balance and comfort. Lead times reflect our commitment to bespoke quality, with every detail inspected before it leaves our Brooklyn workshop.
