It's 2018 and nowadays you will see many girls and women including the celebs wearing many rings on all of their fingers. I am not sure who started this trend, maybe Kim Kardashian? Or is it one of the top Haute Couture/High fashion designers? The person who started with this trend probably things he/she started with it or imitated the trend in Indonesia where older men wear big rings on all of there fingers:

My family in Indonesia called these rings: Voodoo rings, because they keep something evil/witchcraft in those rings. I am not sure if all of those men wear Voodoo rings or just big rings to show off.

I personally don't wear so many rings, let alone these big rings! But when you 3D design them yourself, you feel like wearing them because it looks so real. If only I have a 3D metal printer, I would print them out! But I only have a 3d printer that can print plastic stuff.

Tutorial

I downloaded a human hand in stl file from Grabcad.com and inserted into my design by selecting Insert Mesh.

I started with the spiral ring. Click on Create and select Coil. The diameter and heigh can be ignored here. It's all about the ratio. For the section I chose Square but I softened the edges by adding fillets on the edges. For the ending, I added two small balls. You can do this by clicking on Create and selecting Sphere using operation Join. I changed the appearance in to gold.

For the second ring on the middle finger, I created a curved ring. I needed to offset two planes, place them higher and moved the two faces slightly to get that curved look. With Loft I made the sketch solid. The center part is solid too.

By using Loft again and clicking on the centre part, I could make the center part hollow. I also gave the edges fillets.

For the diamond I sketched an oval and extruded it with a tapered angle of -35 degrees. I changed the appearance into brown glass so it will look a bit like brown diamond or a stone. I gave the diamond/stone a small frame. Just offset the oval sketch with 1 or 2 mm and extrude it.

The third ring I kept it quite simple, but it still has a little detail which is the two cut out rectangles. I basically sketched a circle, offset the circle and extruded it. Then I click on the right face and sketched two equal rectangles. The two rectangles I extruded with operation Cut.

The fourth ring looks like a typical ring we have seen very often. I sketched a circle, extruded it and sketched a rectangle for the rectangular diamond and the frame around it.First I extruded the frame( the offset rectangle) with operation Join. Then for the diamond, I extruded the centre with operation New Body. I changed the appearance in to brown glass and to get that diamond look, I applied bevels on the edges.

The remaining rings are easy to make. I just created small spheres and changed the color in to gold. To make the rings fit, I scaled all the rings.
