John HardyClassic Chain Collection Men's Band Ring, 8MM 925-Sterling Silver Ring

Does anyone have any pics of john hardy rings in person im curious as to detail and dont want to rely on a CGI?

Could the ring be made in different size (for example 9.5)?

Is it real silver? Will it turn green or Brown after a while like stainless steel?

Why is there no john hardy pouch? how do i know this is real?
