Lab-Grown Diamond Engagement Ring

Under the soft glow of Brooklyn light, the elongated marquise diamond catches every glance, its tapered points drawing the eye along a graceful silhouette. This solitaire engagement ring, set in cool 14K white gold, balances bold geometry with delicate refinement.

Handcrafted in our Williamsburg studio, the setting cradles the 9 x 4.5 mm marquise stone with precision prongs that allow maximum light to enter, enhancing the diamond’s signature brilliance and subtle fire. The band’s smooth comfort fit ensures it rests lightly against the finger, designed for daily wear without distraction.

Each lab-grown diamond is cultivated with care, offering clarity and sparkle while reflecting a commitment to sustainable, ethical jewelry practices.

The low-profile setting suits those who prefer an elegant ring that slips easily beneath gloves or stacks seamlessly with a wedding band. Its slender shape complements longer fingers and adds a touch of architectural drama without overwhelming the hand.

Should you need a custom size, resizing is straightforward and handled with the same artisanal attention as the original crafting.
