Avoid Kay and Jarrod (which are both the same company) as they're virulently anti gun.

That and their prices and selection suck.

You need to find a small independent jeweler that 1) knows his stuff and 2) isn't a thief. That's actually harder than finding a mechanic that is both of those.

I haven't heard bad things about Luisa Graff (but her commercials creep me out).

There are a couple small jewelers in Old Colorado City that may not suck (but again we don't have first hand experience with any of them ... there was a little jewelry shop down there that my wife got what we believe to be a good deal on a ring, but they're gone now)
