Description and Product Details
+
Crafted for those drawn to sculptural elegance, this marquise diamond solitaire ring pairs a brilliant, elongated center stone with a distinctive fluted split shank — a signature OG Fine Jewelry silhouette that catches light from every angle. Delicate ball-tipped prongs cradle the diamond securely at four points, letting the stone’s length and clarity take center stage while the ribbed dual-band design adds architectural texture and movement to the finger.
The marquise cut is prized for its elongated, boat-shaped profile, which creates the illusion of greater carat weight and visually lengthens the finger — a timeless choice for engagement rings and statement jewelry alike.
