Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch across the hand. This semi-set solitaire invites you to select a 7 x 5 mm oval stone, whose graceful shape elongates the finger with quiet sophistication.

Crafted in a fixed two-tone band of 18k yellow and 18k yellow and platinum and 18k yellow and platinum, the lightweight shank balances warmth and coolness in a modern-minimal silhouette. The six-prong setting secures the stone with architectural clarity, allowing light to pass freely while maintaining a low-profile comfort fit designed for everyday wear.

Each ring is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every detail to ensure seamless edges and a smooth feel against the skin. The lab-grown diamond you choose reflects a commitment to ethical jewelry, reducing environmental impact without sacrificing brilliance.

Ideal for those who appreciate refined structure and subtle contrast, this solitaire pairs effortlessly with stacking bands or stands alone as a statement of understated confidence. Its low profile makes it glove-friendly and unobtrusive for daily life.

Should you need resizing or guidance on selecting the perfect oval, our Brooklyn studio offers personalized consultations to ensure your ring fits flawlessly and reflects your vision.
