Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of an 8 x 4 mm marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set ring offers a sculptural balance, where the center stone awaits your choice, framed by two delicately crafted side stones.

Forged from 10K yellow gold, the band carries a subtle warmth that complements the marquise’s tapered drama. The artisan finish reveals hand-polished surfaces and secure prong settings designed for everyday wear, while the low-profile mounting ensures comfort beneath gloves or layered with other bands.

Each diamond is lab-grown, reflecting a commitment to sustainable luxury without compromise on brilliance or clarity. The semi-set design invites personal selection, making this ring a unique expression of your story.

Ideal for those who appreciate architectural elegance paired with a soft golden glow, this ring suits slender to medium finger shapes and adapts gracefully to stacking or solo wear. Its balanced proportions keep it wearable and refined.

Resizing is available to ensure a perfect fit, with careful attention to preserving the ring’s structural integrity and finish.
