Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow, drawing the eye along its tapered points. This semi-set halo engagement ring foundation in platinum offers a sleek, low-profile frame designed for everyday grace and resilience.

Crafted with precision, the platinum band is polished to a smooth finish that feels substantial yet comfortable against the skin. Its halo setting, ready to embrace an 8 x 4 mm marquise center, balances architectural elegance with secure prong work, ensuring the stone sits close to the finger for a refined silhouette.

Each piece reflects a commitment to sustainability through the use of lab-grown diamonds, marrying ethical clarity with enduring beauty. The ring’s streamlined design suits those who favor a subtle statement—ideal for stacking or wearing solo without catching on gloves or sleeves.

Should you need adjustments, resizing is handled expertly in-studio to maintain the integrity of the setting and comfort fit. Typical lead times accommodate thoughtful customization without rush.
