I want to build a decorative Diamagnetic Leviatation device using Bismuth and Neodymium Magnets.

I've research how I can achieve this (large Neo Magnet suspended above two Bismuth plates separated by # distance, with a smaller neodymium magnet in between).

How would I find out the varying sizes and amounts of materials if I wanted a 10mm Cube or 8mm Sphere (ideally sphere if possible?) to float between two bismuth plates approximately 50 - 100mm apart?

What's the best approach to finding this out? Assume size of total apparatus should not be more than 300 - 400mm in height and the small magnet should be as visible as possible (bismuth ideally should have the smallest width or radius possible).

Essentially looking to construct something similar to this, except with a larger gap between the bismuth and a more visible small magnet:
