It seems in the past at least for Ashkenazim the wedding rings had houses on them (some of them had a hinge on the roof so that the house opened, from the top)
But it seems not to be used anymore.
Are there Any halacha or Torah Sources that speak about this type of ring?
I understand that there is halacha E"H 31.2 about no stones but most of the houses do not have stones
(Does anyone know what the hinge was for?)
