Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that hints at quiet confidence. This semi-set engagement ring invites you to choose a 6 x 3 mm marquise stone, its pointed ends drawing the eye along the finger with subtle drama.

Crafted in warm 18K yellow gold, the mounting features a delicate solitaire setting designed for everyday wear. The low-profile prongs cradle the stone securely while allowing light to dance freely across its facets. The band’s smooth finish and balanced weight ensure a comfortable fit, ideal for those who favor understated elegance.

Each diamond is lab-grown, reflecting a commitment to sustainable luxury without compromise on clarity or brilliance. This choice honors both the earth and the wearer’s values.

Its slender shape and modest scale suit hands that appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable pieces. The design’s simplicity makes it glove-friendly and unobtrusive for daily life.

Should you wish to adjust the band size, resizing is handled with care in our Williamsburg studio, ensuring a precise fit without altering the ring’s graceful lines.
