Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a glassy, architectural shimmer that draws the eye along its clean lines. This semi-set platinum band awaits your choice of a 10 x 8 mm emerald-shaped center, offering a sleek foundation crafted with artisan precision in our Williamsburg studio.

Each band is hand-finished to a smooth comfort fit, its low-profile setting designed for everyday wear without catching or lifting. The platinum’s cool sheen complements the diamond’s clarity, while the sturdy prongs ensure security without overwhelming the stone’s elegant geometry.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, reducing environmental impact while delivering exceptional clarity and brilliance.

Ideal for those who appreciate architectural form and understated sophistication, this ring suits slender to medium finger sizes and pairs beautifully with stackable bands or a wedding band of your choice. Its subtle profile fits comfortably under gloves or daily wear.
