Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set engagement ring in warm 10K yellow gold offers a refined foundation for a 10 x 5 mm marquise center, ready to be paired with a stone that balances drama and elegance.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that complements the diamond’s distinctive form. The low-profile prong setting secures the stone while allowing light to flood its facets, enhancing the marquise’s signature brilliance and elongating effect on the finger.

Each piece reflects our commitment to ethical jewelry: the center diamond is lab-grown, ensuring clarity and sustainability without compromise. The yellow gold is responsibly sourced and finished with a smooth polish that feels natural against the skin.

Designed for those who appreciate artisan craft and modern romance, this solitaire mounting suits a variety of lifestyles. Its slender band layers effortlessly with wedding bands or stackable rings, while the low profile keeps it glove-friendly and ideal for daily wear.

Should you need a custom fit, resizing is available to ensure the ring sits perfectly. Typical lead times reflect our careful handcrafting process, balancing precision with thoughtful pace.
