I have no clue what is the age, type, value, for this ring.Some type of glaze over stoneware with a soft brass adjustable band any info would be great Thanks
I've no idea! But - in my experience, adjustable rings tend not to be very valuable, at least in a monetary sense, and a ceramic feature on a ring would tend not to be very durable. So wear your ring if you like it, and don't worry too much if it chips or breaks.
