Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set engagement ring foundation in 14K yellow gold invites you to choose a center stone that will embody your story.

Crafted with a slender six-prong setting, the band balances strength and subtlety, designed to showcase the diamond’s graceful silhouette while keeping a low profile for everyday wear. The warm hue of the yellow gold complements the oval’s soft elongation, creating a refined contrast that feels both modern and timeless. Each ring is hand-finished in our Williamsburg studio, ensuring smooth edges and a comfort fit that settles naturally on the finger.

Our commitment to lab-grown diamonds means this piece carries a clear ethical edge—sustainably created with precision and care, free from the environmental and social concerns of traditional mining.

Ideal for those who appreciate minimalist design with architectural clarity, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its lightweight construction makes it glove-friendly and unobtrusive for daily life.

Should you wish to resize or customize the setting further, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
