Simple ring with a cross. It is sized for me - 8-1/2 I believe - but I am including the FreeCAD source file so that you can resize it if you need to. The sketches are labeled as to what they contain so you'll know which sketch(s) to modify for which element.

I recommend that this be printed in the orientation provided with [Supports] enabled, touching the buildplate only, as well as enabling the [Support Interface] in Cura. This makes for a much smoother finish.

Back Story: Over thirty-five years ago, my grandmother gave me a solid gold version of this ring that had a crucifix on it. She passed away almost twenty years ago, but I have worn that ring every day since she gave it to me. I have only removed it for repairs and resizing. I had more money in that ring in repairs than she gave for it originally. The crucifix has long since worn down and a few weeks ago, one of the cross arms broke off. At this point, there is no sense in trying to have it repaired, so I created this version as memorial to my grandmother and that ring. Hopefully someone else will find peace in this as well...
