Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 5.5 mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set foundation in warm 18K rose gold offers a soft glow that complements the diamond’s classic brilliance, inviting your choice of center stone to complete the story.

Each band is meticulously crafted in our Williamsburg studio, where artisan hands shape and polish the rose gold to a smooth comfort fit. The three-stone setting balances presence with wearability, designed to sit low enough for daily life yet elevated enough to catch light from every angle. The semi-set style allows for personalized selection, ensuring your diamond’s cut and clarity harmonize with the warm metal.

Our commitment to lab-grown diamonds means your ring begins with a stone of exceptional clarity and ethical provenance, reflecting a modern approach to sustainability without compromise.

Ideal for those who appreciate a ring that layers beautifully with wedding bands or stackable pieces, this setting’s subtle profile and rounded edges make it glove-friendly and suited to hands of all sizes.

Should you need adjustments, resizing is handled carefully in-house to maintain the ring’s integrity and finish.
