Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye like whispered promises. This three-stone semi-set engagement ring in 14K rose gold offers a delicate blush warmth, framing a 12 x 6 mm center stone yet to be chosen, inviting you to personalize its brilliance.

Crafted with a low-profile setting, the band’s gentle curve ensures comfort for daily wear while the rose gold’s subtle glow complements a range of skin tones. Each prong is hand-finished in our Williamsburg studio, securing stones with precision and a refined touch that balances strength and elegance.

Our commitment to lab-grown diamonds means this ring carries a clarity and sparkle born from sustainable innovation, reflecting a modern approach to ethical jewelry.

The slender band and modest height make this design ideal for those who favor understated sophistication or enjoy stacking with other meaningful pieces. Its shape elongates the finger gracefully, perfect for hands that appreciate architectural lines softened by warm metal.

Should you wish to adjust sizing or explore stone options, our Brooklyn studio offers a collaborative, pressure-free experience tailored to your vision.
