The marquise center is held in a six-prong basket that protects both pointed tips while leaving the elongated outline open to view. The basket keeps the diamond elevated just enough for light to enter beneath the stone while maintaining a balanced profile. The rose cut creates broad reflections that emphasize the long silhouette of the marquise.
Two pear cut side diamonds taper naturally toward the band, adding brilliance without competing with the center. Their rounded ends face outward while the pointed tips lead the eye toward the marquise, creating a smooth transition into the plain comfort shank. Signora Jewels makes every ring to order in your selected precious metal and center diamond size.
