Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo ring foundation in 18K palladium white gold offers a refined stage for a 9 x 4.5 mm marquise center stone, designed to amplify the gem’s signature brilliance and dramatic shape.

Handcrafted in our Williamsburg studio, the band’s low-profile setting balances secure prongs with a delicate halo, enhancing sparkle without excess height. The palladium white gold lends a cool, luminous sheen that resists tarnish, while the artisan finish ensures a smooth comfort fit for daily wear.

Each piece reflects our commitment to ethical jewelry, crafted exclusively for lab-grown diamonds that offer clarity and sustainability without compromise.

Ideal for those who appreciate architectural elegance and a ring that sits close to the finger, this mounting suits slender to medium finger sizes and pairs beautifully with stackable bands or a wedding band designed for seamless alignment.

Should you wish to adjust sizing or explore custom details, our Brooklyn studio offers personalized consultations with flexible lead times tailored to your vision.
