Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye like whispered promises. This semi-set platinum band awaits your choice of a 12 x 6 mm center stone, framed by four delicate side gems that catch the light with subtle brilliance.

Crafted in Williamsburg, the platinum setting offers a cool, weighty feel against the skin, its polished finish smooth enough for daily wear. The five-stone arrangement balances romantic allure with understated elegance, designed to sit low for comfort and ease beneath gloves or alongside other rings.

Each lab-grown diamond reflects a commitment to clarity and sustainability, offering an ethical alternative without compromise on sparkle or character.

Ideal for those who appreciate a refined silhouette that elongates the finger, this setting pairs beautifully with a marquise cut’s dramatic shape, enhancing its architectural grace while maintaining a gentle profile.
