Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that dances with every movement. This three-stone semi-set engagement ring features a 9 x 4.5 mm marquise center, its tapered points drawing the eye along the finger with refined drama.

Crafted from solid 18K yellow gold, the mounting is shaped and polished in our Williamsburg studio with an artisan’s precision. The low-profile setting balances presence with everyday comfort, while the gently curved shank ensures a secure, glove-friendly fit. Each prong is hand-finished to cradle the stone securely, ready for your chosen center diamond.

Our commitment to sustainability is reflected in the option to pair this setting with a lab-grown diamond, offering clarity and brilliance without compromise.

Ideal for those who appreciate architectural elegance and subtle statement, this ring complements slender to medium finger sizes and layers beautifully with stackable bands. Its three-stone design adds depth without bulk, making it a versatile choice for daily wear.

Should you need resizing or prefer a custom consultation, our Brooklyn studio welcomes you to explore options with no pressure and full transparency.
