Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in 18K rose gold offers a delicate balance of modern minimalism and architectural clarity.

Crafted in Williamsburg, the band’s warm rose hue complements the marquise’s dramatic shape, designed to sit low for everyday wear without sacrificing presence. The halo setting frames the center stone with a subtle circle of pavé, enhancing brilliance while maintaining a clean, structured profile. Each curve and angle is hand-finished for smooth comfort and durability.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or sparkle. The 7 x 3.5 mm marquise shape elongates the finger, ideal for those who appreciate refined geometry and confident understatement.

This ring foundation suits a wearer who values a sleek silhouette that layers effortlessly with other bands or stands strikingly alone. Its low profile fits comfortably under gloves and daily wear, making it a versatile choice for a modern lifestyle.
