Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set engagement ring foundation in warm 14K yellow gold awaits a 9 x 4.5 mm marquise center, designed to showcase the stone’s dramatic, vintage-inspired profile.
Handcrafted in our Williamsburg studio, the band features delicate accent settings that balance subtle sparkle with artisanal restraint. The low-profile mounting ensures everyday comfort and ease beneath gloves or stacked alongside other bands, while the polished finish reflects a quiet Brooklyn craftsmanship ethos.
Each piece is designed with lab-grown diamonds in mind, offering clarity and brilliance with a lighter environmental footprint. This ring suits those who appreciate architectural elegance paired with a warm, tactile gold feel.
Resizing is straightforward, handled carefully in-studio to maintain the integrity of the delicate accents and smooth comfort fit. Lead times vary slightly depending on stone selection but remain transparent throughout the custom process.
