Just to point out, the original question was to a specific border style. What you said is accurate to the general, but just in case he wants it more accurate to the given image... It wasn't just a gradient. Rather it was speckled. You do it the same way, it's just a matter of the settings being changed in the gradient style. I don't know which settings does it, or combination does it, (it's pretty easy to figure out) but yeah... Just pointing out if that is specifically what they wanted and for some reason couldn't figure out exactly what to do to get that speckled look.
