Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated points of this marquise shape, it casts a subtle, elegant shadow that draws the eye along the finger’s natural line. This semi-set solitaire ring offers a refined foundation crafted from 18K yellow gold, designed to cradle a 9 x 4.5 mm marquise diamond with a low-profile setting that balances presence and practicality.

The band’s smooth finish and precise proportions ensure a comfortable fit for daily wear, while the secure prong structure minimizes snagging—ideal for those who value both form and function. Each piece is meticulously hand-finished in our Williamsburg studio, where attention to detail meets modern craftsmanship.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or brilliance. The elongated marquise cut naturally elongates the finger, making it a graceful choice for slender or average-sized hands.

Its streamlined silhouette pairs effortlessly with other bands for stacking or stands confidently alone. Should you need resizing or customization, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your lifestyle.
