Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, its tapered points casting delicate shadows across the hand. This halo setting amplifies the stone’s dramatic silhouette, surrounding it with a fine circle of pavé diamonds that enhance every facet’s fire.

Crafted in cool, enduring platinum, the ring’s low-profile setting balances presence with practicality. The band’s smooth comfort fit ensures it rests gently for daily wear, while expert hand finishing polishes every curve to a soft gleam. Each pavé stone is meticulously set by hand in our Williamsburg studio, reflecting a dedication to artisan precision.

Our marquise diamond is lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness without compromise.

Ideal for those who appreciate bold geometry paired with refined craftsmanship, this ring’s slender silhouette elongates the finger gracefully. Its halo design pairs beautifully with stacking bands or stands strikingly alone, suitable for a hand that values both statement and subtlety.

Should you need a custom fit, resizing is handled with care in-house to maintain the ring’s integrity and comfort.
