Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a striking, tapered brilliance that draws the eye along the finger. This three-stone semi-set ring in 18K white gold offers a refined balance between architectural elegance and everyday wearability.

Crafted with a low-profile setting, the band sits close to the hand, minimizing snagging while maintaining a confident presence. The 9 x 4.5 mm marquise center stone is flanked by two smaller side stones, each securely nestled in a precise prong setting that showcases their shape without excess metal. The smooth comfort-fit band is polished to a satin sheen, ensuring it feels as effortless as it looks.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or sparkle. This ring’s streamlined design suits those who appreciate subtle drama and architectural lines, particularly flattering on slender fingers or when stacked with complementary bands.

Should you need a custom fit, resizing is available to ensure the ring complements your hand perfectly. Typical lead times for completion are communicated transparently during your consultation.
