Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a delicate, tapered glow that seems to stretch beyond the finger. This halo setting cradles a 6 x 3 mm lab-grown marquise diamond in polished platinum, where each prong is meticulously shaped to balance security with subtle elegance.

The low-profile halo enhances the diamond’s slender silhouette without adding bulk, making it a refined choice for everyday wear. The platinum band, cool and smooth against the skin, offers a comfort fit that slips on effortlessly and pairs beautifully with stacking rings or a wedding band.

Crafted in our Williamsburg studio, this ring reflects a commitment to ethical jewelry: the center stone is lab-grown, offering clarity and brilliance with a lighter environmental footprint. The halo setting is hand-finished to ensure every facet catches light with quiet intensity.

Ideal for those who appreciate a blend of vintage-inspired romance and modern craftsmanship, this ring complements slender fingers and elongates the hand’s natural lines. Its secure setting and durable platinum make it well suited for daily life, including glove wear in cooler months.
