A cushion Old Mine cut lab grown diamond bezel engagement ring from Signora Jewels.
An approximately 1.86 ct cushion Old Mine cut diamond measuring 7.82 × 7.09 × 4.77 mm is enclosed in a full bezel with an open basket gallery for added light beneath the stone.
Made to order in 11 metals: Silver, 9K/14K/18K Gold (Yellow, White and Rose) and Platinum.
Each metal color is shown in the photos. Choose your preferred center diamond weight and metal from the options on this page.
The full bezel follows the rounded outline of the Old Mine cushion instead of relying on exposed prongs. At Signora Jewels, the polished rim protects every corner while leaving the pavilion visible through an open basket gallery. The result is a smooth profile that highlights the broad reflections unique to an Old Mine cut.
The approximately 1.70 mm comfort-fit shank keeps the ring balanced beneath the larger center stone, while the 6.30 mm setting height provides clearance for light beneath the bezel without making the ring feel overly tall. Every detail is kept clean so the cushion shape remains the focus.
