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 offers a refined foundation to showcase a 7 x 3.5 mm marquise stone, known for its elegant drama and subtle elongation.

Crafted from 14K rose gold, the mounting features a low-profile setting designed for everyday wear. The band’s gentle curve and secure prong placement ensure comfort and durability without sacrificing the diamond’s visibility or brilliance. Finished with a smooth polish, the ring balances technical precision with understated grace.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, offering clarity and sparkle without compromise. The rose gold’s warm hue complements a variety of skin tones, while the semi-set style invites personal choice in selecting the perfect center stone.

Ideal for those who appreciate a sleek silhouette and a ring that fits seamlessly into daily life, this design pairs well with stacking bands or worn solo. Its low profile makes it glove-friendly and unobtrusive, a practical yet elegant companion.

Resizing is available to ensure a precise fit, and the semi-set nature allows for a tailored stone selection with expert guidance. Typical lead times accommodate careful craftsmanship without rush.
