A 16th-century German ring that turns into an astronomical sphere . Astronomers in the 16th and 19th centuries wore rings that unfolded to become tools for calculations. The rings looked like ordinary finger rings, but were actually armillary spheres.

I am not a jewelry person but I would love to have this ring. That is very interesting.
Edit… I will probably buy one.
