I live in Seattle, and work in downtown Seattle. My e-ring is 1.5 ct. Doesn't seem out of place amongst my girlfriends' rings (ranges are 1 ct to 3 ct). Three women I work with recently (w/the last 9 mos) got engaged and their e-rings were 1.74ct; 2.01ct and 2.31ct. I think the average here in Seattle is more like one carat.
