Yes, that makes sense, you’d never see it that in a tiny form. Always good to know the end requirement of a project before using unnecessary detail
In case its helpful I’ve attached that render as a png if you can make use of it. (I posted the original as a screen grab, so while it is a png file it posted as a jpeg, but the new attachment is a “true” png)
As an aside, for this type of metallic finish it’s also good to do what you had done, which is to chamfer or round over the edges. This way they will catch the highlights you get on real world objects which do not have perfect razor edges, otherwise sketchup will always bring edges together sharply and not allow a render to produce that essential detail which makes item more real in the way they catch light. If items are not to be rendered, then this additional geometry may be unecessary as it will increase file size/detail.
As you say, with a ring or hole through the top this could easily be 3D printed to make a form for jewelry.
