Lab-Grown Diamond Engagement Ring

When light catches the delicate curves of this heart-shaped diamond, it unfolds a quiet story of devotion and intimacy. Nestled within a halo of shimmering accents, the 6 x 6 mm center stone radiates a soft brilliance that feels both personal and profound.

Crafted in cool, enduring platinum, the ring’s halo setting balances sparkle with subtlety, designed for everyday wear without overwhelming the hand. The low-profile mount ensures comfort beneath gloves or alongside other bands, while the polished finish reflects the meticulous attention given in our Williamsburg studio.

Each diamond is lab-grown, offering a clarity and ethical transparency that aligns with a modern commitment to sustainability and mindful luxury.

This ring suits those who cherish romantic symbolism paired with practical elegance—its heart shape elongates the finger gently, while the halo adds a whisper of vintage allure without excess.

Should you need a custom fit, resizing is handled with care to preserve the ring’s integrity and balance.
