In this post I'm just going to take you through a few advanced modelling techniques I used to create this wedding ring/band, and again highlight some of the processes I used to generate a render for this product visualisation.
Before rushing into modelling it's good to look at reference images to work out how you can minimise your workflow and start to think about what techniques you will deploy throughout the creation of the object to ensure you are working in an optimal workflow.
One of the first features I noticed in rings/wedding bands were repeating sections. An easy way to minmise and enhance control over your workflow is to build repeating sections of the band and then deform them into the specific shapes.In my case I used the a square socket shape for the diamond sections of the rings to create a repeating shape from.
This involved me creating reference objects and then deforming them along a spline path using the 'Path Deform' modifier. Reference objects allowed me to control the entirety of the diamond repeat sections by modifier just one portion. I.e you can then apply UV mapping or any modifier to the original to effect the references.
In order to create a sharp edge on the diamond geometry I simply used the auto smooth function at a degree of 1 over the entire object in the edit poly modifier settings. See Fig.6
Here are the results before the final texturing and lighting...
