Signora Jewels built this ring around the long 10.50 × 5.40 mm outline of a Dutch marquise center. Four prongs hold the stone at its corners while cathedral shoulders rise from the shank to meet the setting, keeping the diamond clear of the engraved band.
The lower half measures about 2.10 mm wide and 1.80 mm thick. Across the shoulders, the metal opens into a repeating ocean-wave pattern edged with milgrain, so the detail reads from the side without crowding the diamond from above.

The wave pattern is the part you notice after the diamond. From the top, this reads as a clean solitaire; turn the hand and the engraved shoulders appear beneath the raised center.

About Lab Grown Diamonds
The Dutch marquise cut carries its length through a narrow 10.50 × 5.40 mm outline at the reference weight. Its broad center and tapered ends draw light along the stone rather than concentrating it in a round pattern. Each center is selected in F color and VS1 clarity.
Metal, Care & Fit
Yellow gold makes the milgrain and wave cuts easiest to read, while white gold and platinum keep the center and setting visually continuous. Rose gold adds contrast around the diamond. Clean beneath the raised center with warm water, mild soap and a soft brush, then check the four prongs after any hard impact.
FAQ
How high does the Dutch marquise center sit?
The reference setting is approximately 6.80 mm high. Cathedral shoulders support the raised head from both sides, leaving space beneath the diamond for cleaning and light.
Will the pointed ends of the center catch on clothing?
Four corner prongs secure the tapered ends of the Dutch marquise. The points remain more exposed than they would in a bezel, so avoid dragging the ring through knitted fabric.
Can this ring be worn beside a wedding band?
The cathedral shoulders rise toward the center while the lower shank remains about 2.10 mm wide. A straight band can sit alongside it, though the raised ocean-wave shoulders can leave a narrow visual gap near the setting.
What happens to the wave pattern with a larger center?
The ocean-wave and milgrain shank remain the defining band details. The center setting scales to hold the selected diamond weight while preserving the engraved shoulder treatment.
Which metal makes the milgrain easiest to see?
Yellow and rose gold create the strongest shadow around the milgrain edges. White gold and platinum give the ring a more continuous tone from the shank into the four-prong setting.
