Signora Jewels wraps the 8.2 × 6.2 mm Cushion Old Mine center in a complete rim of metal instead of using exposed prongs. At the photographed 1.50 ct weight, the bezel follows the softly rectangular outline closely, protecting the girdle while leaving the full face of the diamond open.
The shoulders divide before they reach the bezel, opening into two polished rails on either side. They spread to approximately 3.80 mm near the center before returning to a 2.20 mm lower shank. The reference setting sits approximately 6.20 mm high.

The open shoulders keep a full bezel from looking heavy. From above, the polished rim draws one clean line around the cushion; immediately beside it, the shank separates and lets the skin show through.

About Lab Grown Diamonds
The Cushion Old Mine center has a softly rectangular outline rather than the strict corners of a princess or emerald cut. At the photographed 1.50 ct weight, it measures approximately 8.2 × 6.2 mm. The full bezel traces that outline closely, leaving the crown exposed while surrounding the girdle with metal.
Metal, Care & Fit
The reference construction uses approximately 5.51 g of 18K gold before the diamond is set. Yellow and rose gold create a stronger visible frame around the center, while white gold and platinum keep the bezel closer in tone to the diamond. Clean around the underside of the bezel and between the split shoulders with warm water, mild soap and a soft brush.
FAQ
How does the full bezel protect this Cushion Old Mine center?
The bezel surrounds the entire girdle with metal. That removes exposed corner prongs and gives the approximately 8.2 × 6.2 mm reference center a continuous protective edge.
What does the open split shank do beside the bezel?
The shoulders divide into two rails as they approach the center. They reach approximately 3.80 mm across near the setting, but the open middle keeps that width from becoming a solid block of metal.
How high does the 1.50 ct reference setting sit?
The photographed construction is approximately 6.20 mm high. The bezel rises above the split shoulders while remaining substantially lower than many tall prong settings.
Can a wedding band sit beside this ring?
The lower shank is approximately 2.20 mm wide, while the shoulders open and rise toward the bezel. A straight band can sit alongside the shank, though the raised center structure can create a small gap near the head.
How should I clean beneath a full bezel?
Use warm water, mild soap and a soft brush around the underside opening of the setting. The split shoulders provide additional access near the center where soap or lotion can collect.
