in rhino : rhino options : render mesh quality

does this setting effect the render quality at all.... I was thinking it was just for the shaded viewports. I have it on jagged and faster usually. Will this effect the quality of render when rendering in maxwell or has it no effect at all?

thanks,

Maxwell and pretty much any renderer can only deal with meshes. The engine does not care about your Nurbs-model at all but is only interested in its polygonal representation.
So yes - the settings here are crucial for quality and speed of your renderings.

I am always thinking that my renders dont look crystal sharp on the edges perhaps this is the mesh settings screwing stuff up?

I know that some jewellers scale their models by 10 but this then wrecks the material properties in some cases.

what mesh settings would you advise for jewellery sized objects? thanks,

It is unfortunately impossible to give general advice on mesh settings. This depends on the topology of your objects. Round shapes like spheres generally need denser mesh settings than - say a cube. For starters I recommend reading all render-mesh releated sections of the Rhino help file. There is also a mesh-section in the Rhino Wiki. Note that it is possible to assign per object mesh settings (in object-properties)

The sharpness problem you mention however will likely have to do with something else: Smoothing. Here the help section for the Weld/Unweld command will get you started. I would not advice to scale your objects up.
It will certainly not help in terms of meshing and smoothing but will lead to unrealistic lighting and DOF conditions.

does the higher the iso settings also make the image more grainy? I seem to remember something in my art college days about the faster the film the more grainy the image but is that true in maxwell?

You remember correctly but this is not the case with Maxwell.
