MissAurora -- the engraved band is 4mm wide, 2mm tall, 4.7 grams of 14K YG, size 6.75. It does kind of look like it's 3mm wide because my hands are so dang big and long; I have a lot of real estate to cover.
jonesishere -- yours is beautiful, too! I have a 7.5mm Moissy cushion and just love the cut of it. Enjoy!
