French Retro gold Old Mine & Old European Diamonds

Unique setting, I've had difficulty finding similar. From an appraiser, French Retro 1940's era with bezel set, flush diamonds. It's a beautiful simple ring with 3 large (old euros & old mine cut) chunky, warm diamonds making up the center. I'm seeing this as a posy or flower engagement ring but different than typical cluster. These 3 diamonds are all bezel & bead set, which make a perfect for stacking. 14k & platinum, 3 old mine & old euro cut diamonds: 3.60mm / 3.80mm / 4.20mm .68tcw
