An oval stretches its weight along one long axis, so a 3 carat oval shows a bigger face than a round of the same weight. It also makes the finger look longer. Ovals can show a darker band across the middle, called a bow-tie, which varies from stone to stone. Set north to south, as it is in these rings, the oval sits along the finger.
Rose gold is gold alloyed with copper, which gives the pink color. 10K is the most pink and the toughest for daily wear. 14K is the middle ground most people choose. 18K has more pure gold, a softer blush and a richer feel, but it scratches a little more easily. Rose gold never needs plating to keep its color.
A solitaire on a thin plain band lets the oval outline do the work. A pavé band adds sparkle along the shank. The halo frames the oval with small lab-grown diamond accents and makes it look bigger still, while the hidden halo keeps the top clean and adds sparkle from the side. The three stone ring and the pear or marquise accent rings widen the look across the finger.
