Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set platinum solitaire mounting is crafted to cradle an 8 x 4 mm marquise center stone with precision, offering a secure yet unobtrusive setting that keeps the profile low and comfortable for everyday wear.

Forged from solid platinum, the band is polished to a subtle sheen that complements the diamond’s fiery facets without overwhelming them. The mounting’s streamlined design ensures it sits close to the hand, minimizing snagging and making it an excellent choice for those who prefer a sleek, glove-friendly silhouette. Each ring undergoes meticulous finishing and inspection in our Williamsburg studio, where expert hands refine every detail.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional clarity and sparkle. The marquise shape’s tapered points add a touch of architectural drama, elongating the finger and enhancing the solitaire’s modern geometry.

This ring suits someone who values understated elegance and technical assurance—ideal for daily wear and effortless stacking with complementary bands. Should you need resizing or customization, our Brooklyn studio offers personalized consultations to ensure a perfect fit and finish.
