Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set engagement ring invites you to choose a 6 x 3 mm marquise stone, whose tapered points and graceful curve evoke a quiet drama and refined elegance.

Crafted in warm 14K yellow gold, the mounting features a delicate solitaire setting designed for everyday wear. The low-profile prongs cradle the stone securely while allowing light to dance freely across its facets. The band’s subtle taper and smooth finish ensure a comfortable fit that feels natural from morning coffee to evening strolls.

Each piece reflects a commitment to sustainability through lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint. This ring’s slender shape suits hands that appreciate understated sophistication and works beautifully as a standalone statement or paired with a stack of complementary bands.

Should you need adjustments, resizing is handled expertly in-studio to maintain the ring’s balance and comfort. Lead times are tailored to your design choices, ensuring a thoughtful, pressure-free process.
