The listing, Jade gauges has ended.
I won these gauges a couple weeks ago. They were listed as 5/8", but they're just a little smaller than that. I wouldn't go as far as saying they're 7/16", but some where between 5/8" & 7/16". They'd be great for someone who is stretching their ears, since 7/16" to 5/8" is such a big stretch.
