Armillary Sphere Ring

Inspired by the ancient armillary sphere, this ring can unfold into a striking replica of this historical scientific device. This astral souvenir is a must-keep for those who have their eyes on the heavens. 

Based on early astronomical devices for representing the great circles of the heavens, some of which included the horizon, meridian, equator, tropics, polar circles, and an ecliptic loop. In the 17th and 18th centuries such models—either suspended, rested on a stand, or affixed to a handle—were used to show the difference between the Ptolemaic theory of a central Earth and the Copernican theory of a central Sun. 

Sometimes it can be hard to open a foldable ring, but not with this one! We have tested it and it's smooth to open this armillary sphere foldable ring; the inner ring rotates easily. 

Are you - or is someone in your life - inspired by science and the fascinating history of astronomy? Don't be surprised when this ring gets noticed, most will never have seen anything like this before.
