Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to dance with every movement. This semi-set halo ring in 18K rose gold offers a warm embrace to a 12 x 6 mm center stone, framing it with a subtle circle of smaller diamonds that enhance its graceful taper.

Handcrafted in Williamsburg, the band’s gentle curve and polished finish ensure a comfortable fit that rests lightly against the finger. The low-profile halo setting balances presence with wearability, designed to slip easily beneath gloves or stack alongside other bands without catching.

Each piece is meticulously inspected to meet exacting standards, marrying traditional craftsmanship with modern precision. The rose gold’s soft blush complements the marquise’s dramatic shape, which elongates the hand with a refined, architectural elegance.

Our commitment to sustainability is reflected in the use of a lab-grown diamond, offering clarity and brilliance without compromise. This ethical choice aligns with a mindful approach to fine jewelry, crafted for daily life and lasting significance.

Ideal for those who appreciate a romantic yet modern silhouette, this ring suits slender to medium finger sizes and pairs beautifully with delicate wedding bands. Resizing is available to ensure a perfect fit, with typical lead times communicated during your design consultation.
