Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand, where a 12 x 6 mm marquise diamond catches light with a poised, tapered brilliance. This semi-set halo engagement ring in 10K white gold offers a refined foundation, ready to cradle your chosen center stone with precision.

Crafted for everyday elegance, the low-profile setting keeps the silhouette sleek and close to the finger, while the halo design amplifies sparkle without adding bulk. The smooth band balances comfort and durability, shaped to wear gracefully through daily moments.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity and conscience. This ring’s design suits those who appreciate architectural form with a modern edge, especially flattering on slender fingers and ideal for stacking alongside complementary bands.

Should you need adjustments, resizing is straightforward, ensuring a tailored fit without compromising the ring’s integrity. Lead times are transparent, with personalized guidance throughout the custom design process.
