Fairy Lamp? Candle holder? What is it?

This has been in the family for over 100 years. It is about six inches high and five inches in diameter and has a ring attached to the base for insertion of index finger to carry it. The cover comes off and a votive candle can be placed on it. A vent hole at the top allows the smoke to escape. It has been called a “fairy light,” but nothing I’ve seen on Google comes even close to this. It has no markings for date or manufacturer. Can you identify it?
