Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a line of refined clarity and quiet confidence. This 8 x 4 mm stone, set in cool platinum, balances architectural precision with a modern-minimalist spirit.

The platinum band is crafted for everyday grace—polished to a soft sheen and designed with a low-profile setting that nestles close to the finger, offering both comfort and subtlety. Accents along the shank enhance the diamond’s brilliance without interrupting its sleek geometry, while expert hand finishing ensures each facet reflects light with crisp definition.

Our lab-grown diamond embodies a commitment to ethical jewelry, created with minimal environmental impact and traceable origins.

Ideal for those who appreciate structured elegance, this ring’s slim profile and smooth edges make it glove-friendly and stackable with other bands, fitting seamlessly into a modern lifestyle.

Should you need a custom fit, resizing is handled delicately in-studio to preserve the ring’s integrity and finish.
