Some claim it will smooth the action but I don't see how it would be any better than just a regular polished finish.
I like how it looks on most guns that have it.

Of course it's good. Talk about increasing your accuracy.
Also, in case you weren't aware, I'll let you in on a little trade secret: pinstripes give your car 30 more horsepower.

And flames painted on the fenders makes it hotter. :)

I had to come back and post something a bit more serious.
Typically, a "jeweled bolt" has no jewels in it. It has always meant it had a special deep polish that looks like swirls, in rows, next to each other. It is SUPPOSED to hold a bit more oil, reduce wear on friction-prone parts.

depends on where the part is.the origional term was/is "engine turned finish" why,I don't know.on metal to metal contact points the swirls do hold more oil/lubricant than a smooth surface.on non contact surfaces,would still hold more oil,but serve no purpose other than looking good. jwr

Opinions vary, I always thought it looked cheesy.

Jeweling does make small groves that hold oil on a friction bearing surface. By dividing the surface contact in closely fitted moving parts between oil filled recesses and metal, lubricant can remain where it needs to be, reducing friction and wear, thereby maintaining those close tolerances. This the idea, at least, behind the Registered Magnum's concentric hammer grooves. I've seen the technique work well on other firearms actions such as beautifully fitted rifle bolts, and I've seen it work well on hydraulic actuators of jet aircraft. The key is to have the close tolerances to start with.
Properly used on close tolerance moving parts, jeweling works. If it is placed on loosely fitted parts as decoration, it's just fashion, and a stupid one at that. If your gun works without jeweling, it does not need jeweling.
