Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow across the hand. This semi-set solitaire ring offers a delicate foundation for a 7 x 5 mm oval center stone, ready to be chosen and cherished.

Crafted from warm 10K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth, comfortable fit that sits low against the finger. The setting’s minimalist prongs cradle the stone securely while allowing light to dance freely through its facets, enhancing the oval’s signature elongation and soft brilliance.

Each piece reflects our commitment to ethical jewelry: the design embraces a lab-grown diamond’s clarity and sustainability without compromise. The rose gold’s subtle blush complements the stone’s glassy elegance, making this ring a graceful choice for daily wear or stacking with other bands.

Its low-profile silhouette suits hands seeking understated refinement, while the semi-set format invites personal selection of the perfect oval diamond. Resizing is straightforward, ensuring a tailored fit that feels natural and effortless.
