Signora Jewels keeps this ring centered on one long 13.92 × 6.56 mm marquise. The photographed 2.040 ct diamond is held by six prongs, including dedicated settings over both narrow tips. Four additional contact points support the long sides without adding a halo or side stones.
The polished shoulders sweep upward into the center head, leaving open space beneath the diamond. The CAD puts the reference setting at 6.30 mm high. With no accent diamonds on the band, the marquise carries the entire 2.040 ct diamond weight on its own.

About Lab Grown Diamonds
The reference marquise weighs 2.040 ct and measures 13.92 × 6.56 mm. There are no additional diamonds in the ring, so the main diamond weight and total diamond weight are both 2.040 ct. Its elongated outline is supported at six points, including both narrow tips.
Metal, Care & Fit
The CAD gives an 18K metal weight of 3.90 g. The open structure beneath the center provides direct cleaning access to the pavilion. Use warm water, mild soap and a soft brush underneath the diamond, and pay particular attention to the settings protecting both pointed ends.
FAQ
What is the total diamond weight of this 2.040 ct marquise ring?
The main marquise weighs 2.040 ct and there are no side diamonds. The CAD reference ring therefore has 2.040 ct total diamond weight.
How is the 13.92 × 6.56 mm marquise secured?
Six prongs secure the center, including dedicated contact at both pointed ends. Four additional prongs support the sides while leaving much of the elongated perimeter visible.
How high does the reference setting sit?
The CAD shows a 6.30 mm setting height. The shoulders rise toward the center while leaving an open structure beneath the diamond.
How does the plain shank affect stacking?
The shank remains free of side diamonds and decorative stone settings. The raised center structure determines how closely a straight wedding band can approach the head.
How should the marquise setting be cleaned?
Use warm water, mild soap and a soft brush through the open underside. Brush gently around all six settings, with particular attention to the metal protecting the two pointed tips.
