Ah, Blender! I have used Blender myself, but not for anything really serious, I wanted to try out 3D animation. I learnt to sculpt, model, uv unwrap, rig and colour, but I never got to animate complex 3D models. But I made a 3D character (a man) from scratch. It came as a surprise how a free open source software can be that great.
That's a good looking piece of work, this pendant.
