I have a weakness for rose cut diamonds, any size, shape or color. This exceptionally fine oval rose cut diamond is bezel set in 18ky gold on a roll printed oval concave disc.  The shimmering surface of the palladium and 18ky band is created by forging the wire with a textured hammer before fabrication.
