Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set solitaire ring invites you to choose a center stone that balances vintage allure with modern refinement.

Crafted in 10K white gold, the slender band is polished to a soft sheen, designed to sit low and close to the finger for everyday comfort. The prong setting is engineered to secure the marquise shape while allowing maximum light to pass through, enhancing the diamond’s signature brilliance and fire.

Each piece reflects a commitment to sustainability, featuring a lab-grown diamond option that offers clarity and sparkle without compromise. This ethical choice aligns with a mindful approach to fine jewelry, rooted in respect for both craft and planet.

The ring’s streamlined profile suits hands that appreciate subtle drama—ideal for stacking with complementary bands or wearing solo as a statement of understated romance. Its gentle curve and narrow width make it glove-friendly and unobtrusive for daily wear.

Should you wish to adjust the fit, resizing is available with care to preserve the band’s smooth finish and structural integrity. Typical lead times accommodate the custom selection of your marquise center stone.
