Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to stretch beyond the finger. This three-stone semi-set engagement ring foundation in 10K yellow gold invites you to select a center stone that echoes your story.

Crafted with a low-profile setting, the gently curved band balances presence with everyday ease, its polished finish warm against the skin. Each prong is meticulously shaped to cradle your chosen marquise diamond securely while allowing light to dance through its tapered points.

Our commitment to sustainability shines through the lab-grown diamond option, offering clarity and brilliance with a lighter environmental footprint.

The slender band and modest height make this ring an ideal companion for those who favor subtle elegance or enjoy stacking with other bands. Its shape naturally elongates the finger, lending a graceful, refined silhouette.

Should you need adjustments, resizing is straightforward, ensuring a comfortable fit tailored to your hand.
